Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

* scalb should not be declared for __USE_XOPEN2K8, and scalbf and

This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and

This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the

Make bits/math-finite.h conditions match other headers (bug 19205).

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on

some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.

Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various
functions under conditions not matching those under which the normal
versions are declared.
* math.h only ever includes bits/mathcalls.h to declare float and long
double functions if __USE_ISOC99, but bits/math-finite.h declares
some float functions regardless (long double ones are conditioned on
__MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a
conformance bug because C90 reserves the float and long double
names, but is still contrary to good glibc practice. For some other
functions in older XSI standards it *is* a conformance bug.)
* Some functions are defined as inlines using lgamma_r functions under
conditions where those lgamma_r functions are not themselves
declared.
* hypot is declared under __USE_XOPEN || __USE_ISOC99 in
bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h.
* float and long double versions of Bessel functions should be limited
to __USE_MISC (as in bug 18977).
* gamma should not be declared for __USE_XOPEN2K (as in bug 18967).
* remainder should be restricted to __USE_XOPEN_EXTENDED ||
__USE_ISOC99, not unconditional.
* scalb should not be declared for __USE_XOPEN2K8, and scalbf and
scalbl are non-POSIX (as in bug 18967).
This patch fixes all these issues (it doesn't seem worth splitting
them into separate patches or bugs). I put __USE_ISOC99 conditionals,
where needed, around both float and long double declarations, even
though formally redundant around the long double declarations because
__MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed
clearer that way. The missing declarations of lgamma_r functions are
dealt with by directly using declarations of __lgamma*_r_finite, in
the implementation namespace, rather than having the inlines rely on
asm redirection of lgamma*_r.
After this patch, there are some apparently redundant nested
__USE_ISOC99 conditionals in lgamma / gamma definitions. These
actually reflect a separate bug (the correct condition for the lgamma
inline functions to set signgam is __USE_MISC || __USE_XOPEN, the
condition under which signgam is declared, rather than disabling
setting it if __USE_ISOC99, which includes XSI POSIX versions for
which signgam *should* be set). They'll be fixed as part of a fix for
that bug, which will also add tests for these inlines. I've put a
note about more general conform/ test coverage for -ffinite-math-only
on
<https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>,
alongside other options for which this is also relevant (some of which
have also had such bugs in the past relating to mismatched
conditionals).
I also intend to enable the main libm-test.inc tests for the
math-finite.h functions, but some other bugs in __*_finite need fixing
first.
