5ca10a0c9a powerpc: Remove HAVE_ASM_GLOBAL_DOT_NAME define
With AIX port deprecated there is no need to check/define
HAVE_ASM_GLOBAL_DOT_NAME anymore since the current minimum binutils
supported (2.22) does not emit global symbol with dot.

This patch removes all the HAVE_ASM_GLOBAL_DOT_NAME definition and
checks for powerpc64 port.

e4363cfb57 hppa: Fix feupdateenv and fesetexceptflag (Bug 18111).
The function feupdateenv has been fixed to correctly handle FE_DFL_ENV
and FE_NOMASK_ENV.

The fesetexceptflag function has been fixed to correctly handle setting
the new flags instead of just OR-ing the existing flags.

This fixes the test-fenv-return and test-fenvinline failures on hppa.

fae1aa8d22 hppa: Fix feholdexcpt and fesetenv (Bug 18110).
The constraints in the inline assembly in feholdexcept and fesetenv
are incorrect. The assembly modifies the buffer pointer, but doesn't
express that in the constraints. The simple fix is to remove the
modification of the buffer pointer which is no longer required by
the existing code, and adjust the one constraint that did express
the modification of bufptr.

The change fixes test-fenv when glibc is compiled with recent gcc.

068a627455 soft-fp: Add _FP_UNREACHABLE.
This patch makes soft-fp use a new macro _FP_UNREACHABLE in place of
calling abort in unreachable default cases of switch statements.
_FP_UNREACHABLE expands to call __builtin_unreachable for GCC 4.5 and
later; the fallback to abort is thus only for kernel use.

Tested for powerpc-nofpu that installed stripped shared libraries are
unchanged by this patch.  Also tested with the math/ tests for mips64
(in the case of fma there *was* previously an abort call generated,
unlike for the other operations - one switch only deals with a subset
of classes for one operand based on what could have been generated in
the earlier part of fma, whereas the other switches deal with all
combinations of two classes - and this is apparently too complicated
for the default case to have been optimized away).

	* soft-fp/soft-fp.h (_FP_UNREACHABLE): New macro.
	* soft-fp/op-common.h (_FP_MUL): Use _FP_UNREACHABLE instead of
	abort.
	(_FP_FMA): Likewise.
	(_FP_DIV): Likewise.

a2f8be9c83 soft-fp: Use multiple-include guards.
This patch makes soft-fp headers consistently use multiple-include
guards, something previously done mainly only in the Linux kernel
version.  The guard macros aren't the same as those used in the Linux
kernel, but there seems to be enough variation in such guards in Linux
kernel code that hopefully this version will be acceptable there.

Tested for powerpc-nofpu that installed stripped shared libraries are
unchanged by this patch.

	* soft-fp/double.h [SOFT_FP_DOUBLE_H]: New multiple-include guard.
	* soft-fp/extended.h [SOFT_FP_EXTENDED_H]: Likewise.
	* soft-fp/op-1.h [SOFT_FP_OP_1_H]: Likewise.

b838844bc5 soft-fp: Support conditional zero-initialization in declarations.
In the Linux kernel, some architectures have a single function that
uses different kinds of unpacking and packing depending on the
instruction being emulated, meaning it is not readily visible to the
compiler that variables from _FP_DECL and _FP_FRAC_DECL_* macros are
only used in cases where they were initialized.  The existing copy of
soft-fp in the Linux kernel uses zero-initialization to avoid warnings
in this case, so while frowned upon as a warning suppression mechanism
in code built for glibc it seems appropriate to have such
zero-initialization conditional on __KERNEL__.  This patch duly adds
it, via a macro _FP_ZERO_INIT that expands to empty for non-kernel
compilations.

Tested for powerpc-nofpu that installed stripped shared libraries are
unchanged by this patch.

	* soft-fp/soft-fp.h (_FP_ZERO_INIT): New macro.  Define depending
	on [__KERNEL__].
	* soft-fp/op-1.h (_FP_FRAC_DECL_1): Use _FP_ZERO_INIT.
	* soft-fp/op-2.h (_FP_FRAC_DECL_2): Likewise.
	* soft-fp/op-common.h (_FP_DECL): Likewise.

e0ed2fb40a Replace __attribute__((visibility("protected")))
With copy relocation, address of protected data defined in the shared
library may be external.  Compiler shouldn't asssume protected data will
be local.  But due to

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248

__attribute__((visibility("protected"))) doesn't work correctly, we need
to use asm (".protected xxx") instead.

	* elf/ifuncdep2.c (global): Replace
	__attribute__((visibility("protected"))) with
	asm (".protected global").
	* elf/ifuncmod1.c (global): Likewise.
	* elf/ifuncmod5.c (global): Likewise.

fa9dda6493 soft-fp: Condition sfp-machine.h include path on __KERNEL__.
My Linux kernel patch to update the kernel to current glibc soft-fp
<https://sourceware.org/ml/libc-alpha/2015-02/msg00107.html> still
leaves a few small differences between the two copies of soft-fp.

I think it's desirable to avoid such differences completely if
possible by having one set of sources suitable for use in both places.
To that end, this patch introduces a conditional on __KERNEL__ for the
path by which sfp-machine.h is included.

Tested for powerpc-nofpu that installed stripped shared libraries are
unchanged by this patch.

	* soft-fp/soft-fp.h [!_LIBC && __KERNEL__]: Include
	<asm/sfp-machine.h> instead of <sfp-machine.h>.

7e7af3496e manual: complete example in error message documentation
The manual gives "an example showing how to handle failure to open a
file correctly."  The example function, open_sesame, uses the
newly-introduced strerror function and errno and
program_invocation_short_name variables.  It fails to specify GNU
extensions, however, so attempts to use it in the following way:

    int main (void) {open_sesame ("badname");}

fail during compilation with "error: ‘program_invocation_short_name’
undeclared", indicating the example is incomplete.  The presence of
"#include"s suggest everything neccesary for the function to work should
be present.  For completeness, the example is lacking the following line:

    #define _GNU_SOURCE

as the declarations of program_invocation_*name in errno.h are wrapped
in an "#ifdef __USE_GNU" conditional.

The documentation of the variables is also expanded, adding that their
definition lies in errno.h and noting specifically they are GNU
extensions.

6d08b0223a Correct __ASSUME_PRLIMIT64 for hppa/microblaze/sh (bug 17779).
__ASSUME_PRLIMIT64 is defined in kernel-features.h for kernels 2.6.36
and later, but hppa, microblaze and sh did not add the prlimit64
syscall until 2.6.37.  This patch adds corresponding undefines of
__ASSUME_PRLIMIT64 to those architectures' kernel-features.h files.

(This concludes the kernel-features.h fixes arising out of the review
- limited to macros defined in the architecture-independent
kernel-features.h file - I did in connection with the move to 2.6.32
minimum kernel version.  For that subset of macros - I didn't check
any purely architecture-specific macros - I think they are now defined
for the correct kernel versions on each architecture after this
patch.)
