As with other long double identifiers, float128_private.h has a
redefinition of SET_RESTORE_ROUNDL. However, that redefinition is
broken, since this is a macro with one argument being defined to take
no arguments. This patch fixes the redefinition. (x86_64 needs the
redefinition because SET_RESTORE_ROUNDL only changes the x87 rounding
mode, whereas _Float128 arithmetic uses the SSE rounding mode instead
on x86_64.)
Tested for x86_64 (in conjunction with float128 patches).
* sysdeps/ieee754/float128/float128_private.h
[SET_RESTORE_ROUNDF128] (SET_RESTORE_ROUNDL): Take an argument and
pass it to SET_RESTORE_ROUNDF128.
float128_private.h redefines ieee754.h identifiers ieee854_long_double
and IEEE854_LONG_DOUBLE_BIAS to map them to identifiers from
ieee754_float128.h.
This causes problems when ieee754.h is included after
float128_private.h and it's a version of ieee754.h that also defines
those identifiers; specifically, sysdeps/ieee754/ieee754.h, which
defines those identifiers for the x86 extended format. This patch
fixes this by ensuring an include of ieee754.h from float128_private.h
before the redefinitions.
Tested for x86_64 (in conjunction with float128 patches).
* sysdeps/ieee754/float128/float128_private.h: Include
<ieee754.h>.
Reuse the code for __mpn_extract_long_double to implement
__mpn_extract_float128.
* include/gmp.h: Include bits/floatn.h
(__mpn_extract_float128): Declare when __HAVE_DISTINCT_FLOAT128 is 1.
* stdlib/gmp-impl.h: Also check if alloca is not defined before
including stack-alloc.h. It could have been defined by other header
which not necessarily defines HAVE_ALLOCA.
* sysdeps/ieee754/float128/Makefile: New file.
* sysdeps/ieee754/float128/float1282mpn.c: New file.
* sysdeps/ieee754/float128/float128_private.h: Include gmp.h before
redefining __mpn_extract_long_double to __mpn_extract_float128, then
redefine __mpn_extract_long_double to __mpn_extract_float128.
* sysdeps/ieee754/ldbl-128/ldbl2mpn.c: Replace long double with
_Float128 to allow float128_private.h overrides.
This change defines float128_private.h which contains
macros used to override long double naming conventions
when building a ldbl file.
* math/math.h [__HAVE_FLOAT128 && __GLIBC_USE (IEC_60559_TYPES_EXT)]
(SNANF128): New macro.
* math/e_sqrtf128.c: New file.
* math/s_fmaxmag_template.c: Include math_private.h in order to
make inline expansion of fabs128().
