Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Obsolete matherr, _LIB_VERSION, libieee.a.
This patch obsoletes support for SVID libm error handling (the system
where a user-defined function matherr is called on a libm function
error; only enabled if you also set _LIB_VERSION = _SVID_ or
_LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global
variable to control libm error handling. matherr and _LIB_VERSION are
made into compat symbols, not supported for new ports or for static
linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_,
so disabling errno setting for some functions) is also removed, and
all the related definitions are removed from math.h.
The manual already recommends against using matherr, and it's already
not supported for _Float128 functions (those use new wrappers that
don't support matherr, only errno) - this patch means that it becomes
possible to e.g. add sinf32 as an alias to sinf without that resulting
in undesired matherr support in sinf32 for existing glibc ports.
matherr support is not part of any standard supported by glibc (it was
removed in XPG4).
Because matherr is a function to be defined by the user, of course
user programs defining such a function will still continue to link; it
just quietly won't be used. If they try to write to the library's
copy of _LIB_VERSION to enable SVID error handling, however, they will
get a link error (but if they define their own _LIB_VERSION variable,
they won't).
I expect the most likely case of build failures from this patch to be
programs with unconditional cargo-culted uses of -lieee (based on a
notion of "I want IEEE floating point", not any actual requirement for
that library).
Ideally, the new-port-or-static-linking case would use the new
wrappers used for _Float128. This is not implemented in this patch,
because of the complication of architecture-specific (powerpc32 and
sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard
directly. Thus, the old wrappers and __kernel_standard are still
built unconditionally, and _LIB_VERSION still exists in static libm.
But when the old wrappers and __kernel_standard are built in the
non-compat case, _LIB_VERSION and matherr are defined as macros so
code to support those features isn't actually built into static libm
or new ports' shared libm after this patch.
I intend to move to the new wrappers for static libm and new ports in
followup patches. I believe the sqrt wrappers for powerpc32 and sparc
can reasonably be removed. GCC already optimizes the normal case of
sqrt by generating code that uses a hardware instruction and only
calls the sqrt function if the argument was negative (if
-fno-math-errno, of course, it just uses the hardware instruction
without any check for negative argument being needed). Thus those
wrappers will only actually get called in the case of negative
arguments, which is not a case it makes sense to optimize for. But
even without removing the powerpc32 and sparc wrappers it should still
be possible to move to the new wrappers for static libm and new ports,
just without having those dubious architecture-specific optimizations
in static libm.
Everything said about matherr equally applies to matherrf and matherrl
(IA64-specific, undocumented), except that the structure of IA64 libm
means it won't be converted to using the new wrappers (it doesn't use
the old ones either, but its own error-handling code instead).
As with other tests of compat symbols, I expect test-matherr and
test-matherr-2 to need to become appropriately conditional once we
have a system for disabling such tests for ports too new to have the
relevant symbols.
Tested for x86_64 and x86, and with build-many-glibcs.py.

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my

Obsolete matherr, _LIB_VERSION, libieee.a.
This patch obsoletes support for SVID libm error handling (the system
where a user-defined function matherr is called on a libm function
error; only enabled if you also set _LIB_VERSION = _SVID_ or
_LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global
variable to control libm error handling. matherr and _LIB_VERSION are
made into compat symbols, not supported for new ports or for static
linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_,
so disabling errno setting for some functions) is also removed, and
all the related definitions are removed from math.h.
The manual already recommends against using matherr, and it's already
not supported for _Float128 functions (those use new wrappers that
don't support matherr, only errno) - this patch means that it becomes
possible to e.g. add sinf32 as an alias to sinf without that resulting
in undesired matherr support in sinf32 for existing glibc ports.
matherr support is not part of any standard supported by glibc (it was
removed in XPG4).
Because matherr is a function to be defined by the user, of course
user programs defining such a function will still continue to link; it
just quietly won't be used. If they try to write to the library's
copy of _LIB_VERSION to enable SVID error handling, however, they will
get a link error (but if they define their own _LIB_VERSION variable,
they won't).
I expect the most likely case of build failures from this patch to be
programs with unconditional cargo-culted uses of -lieee (based on a
notion of "I want IEEE floating point", not any actual requirement for
that library).
Ideally, the new-port-or-static-linking case would use the new
wrappers used for _Float128. This is not implemented in this patch,
because of the complication of architecture-specific (powerpc32 and
sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard
directly. Thus, the old wrappers and __kernel_standard are still
built unconditionally, and _LIB_VERSION still exists in static libm.
But when the old wrappers and __kernel_standard are built in the
non-compat case, _LIB_VERSION and matherr are defined as macros so
code to support those features isn't actually built into static libm
or new ports' shared libm after this patch.
I intend to move to the new wrappers for static libm and new ports in
followup patches. I believe the sqrt wrappers for powerpc32 and sparc
can reasonably be removed. GCC already optimizes the normal case of
sqrt by generating code that uses a hardware instruction and only
calls the sqrt function if the argument was negative (if
-fno-math-errno, of course, it just uses the hardware instruction
without any check for negative argument being needed). Thus those
wrappers will only actually get called in the case of negative
arguments, which is not a case it makes sense to optimize for. But
even without removing the powerpc32 and sparc wrappers it should still
be possible to move to the new wrappers for static libm and new ports,
just without having those dubious architecture-specific optimizations
in static libm.
Everything said about matherr equally applies to matherrf and matherrl
(IA64-specific, undocumented), except that the structure of IA64 libm
means it won't be converted to using the new wrappers (it doesn't use
the old ones either, but its own error-handling code instead).
As with other tests of compat symbols, I expect test-matherr and
test-matherr-2 to need to become appropriately conditional once we
have a system for disabling such tests for ports too new to have the
relevant symbols.
Tested for x86_64 and x86, and with build-many-glibcs.py.

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Add tests for namespace for static linking.
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)
