*	posix: Sync glob with gnulib [BZ #1062]	Adhemerval Zanella	2017-09-08	13	-48/+101
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch syncs posix/glob.c implementation with gnulib version b5ec983 (glob: simplify symlink detection). The only difference to gnulib code is * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there were not already defined. Gnulib code which uses HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead the patch check for each definition instead. Also, the patch requires additional globfree and globfree64 files for compatibility version on some architectures. Also the code simplification leads to not macro simplification (not need for NO_GLOB_PATTERN_P anymore). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #1062] * posix/Makefile (routines): Add globfree, globfree64, and glob_pattern_p. * posix/flexmember.h: New file. * posix/glob_internal.h: Likewise. * posix/glob_pattern_p.c: Likewise. * posix/globfree.c: Likewise. * posix/globfree64.c: Likewise. * sysdeps/gnu/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/alpha/globfree.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/oldglob.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/globfree.c: Likewise. * sysdeps/wordsize-64/globfree.c: Likewise. * sysdeps/wordsize-64/globfree64.c: Likewise. * posix/glob.c (HAVE_CONFIG_H): Use !_LIBC instead.

*	Prefer new libm function wrappers for !LIBM_SVID_COMPAT.	Joseph Myers	2017-09-05	94	-30/+167
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The initial obsoletion of SVID libm error handling left the old wrappers and __kernel_standard still being used for new ports and static linking, just with macro definitions of _LIB_VERSION and matherr that meant symbols with those names were never actually used and the code for different error handling variants could be optimized out. This patch cleans things up further by eliminating the __kernel_standard use for new ports and static linking. Now, the old wrappers no longer generate any code in the !LIBM_SVID_COMPAT case, while the new errno-only wrappers that were added for float128 support are now also used for float, double and long double in that case. The changes are generally straightforward. The w_scalb_compat wrappers continue to be used (scalb is obsolescent in the sense of not being supported for float128, but is present in supported standards - the 2001 edition of POSIX and earlier XSI versions - so remains supported for static linking and new ports, as do the float and long double variants that are existing GNU extensions). Those wrappers would only call __kernel_standard in the _LIB_VERSION == _SVID_ case. Since we would like to be able to compile most of glibc without optimization, relying on a static function whose only use is under an if (0) condition being optimized away to avoid an undefined __kernel_standard reference may not be a good idea. Thus, the relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals added to guarantee it's not built at all in the case where __kernel_standard does not exist. Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added. ia64 gets dummy w_.c to prevent those files being built where they would conflict with the ia64 libm, as with its existing w__compat.c. Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the math/ wrappers and in the long double wrappers in ldbl-opt (to avoid them setting up aliases and symbol versions for undefined symbols). I hope that future cleanups to how libm function aliases and symbol versioning are done will eliminate the need for most of the ldbl-opt wrappers.

*	Obsolete pow10 functions.	Joseph Myers	2017-09-01	24	-397/+33
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	There are various bits/huge_val.h headers to define HUGE_VAL and related macros. All of them use __builtin_huge_val etc. for GCC 3.3 and later. Then there are various fallbacks, such as using a large hex float constant for GCC 2.96 and later, or using unions (with or without compound literals) to construct the bytes of an infinity, with this last being the reason for having architecture-specific files. Supporting TS 18661-3 _FloatN / _FloatNx types that have the same format as other supported types will mean adding more such macros; needing to add more headers for them doesn't seem very desirable. The fallbacks based on bytes of the representation of an infinity do not meet the standard requirements for a constant expression. At least one of them is also wrong: sysdeps/sh/bits/huge_val.h is producing a mixed-endian representation which does not match what GCC does. This patch eliminates all those headers, defining the macros directly in math.h. For GCC 3.3 and later, the built-in functions are used as now. For other compilers, a large constant 1e10000 (with appropriate suffix) is used. This is like the fallback for GCC 2.96 and later, but without using hex floats (which have no apparent advantage here). It is unambiguously valid standard C for all floating-point formats with infinities, which covers all formats supported by glibc or likely to be supported by glibc in future (C90 DR#025 said that if a floating-point format represents infinities, all real values lie within the range of representable values, so the constraints for constant expressions are not violated), but may generate compiler warnings and wouldn't handle the TS 18661-1 FENV_ROUND pragma correctly. If someone is actually using a compiler with glibc that does not claim to be GCC 3.3 or later, but which has a better way to define the HUGE_VAL macros, we can always add compiler conditionals in with alternative definitions. I intend to make similar changes for INF and NAN. The SNAN macros already just use __builtin_nans etc. with no fallback for compilers not claiming to be GCC 3.3 or later.

Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the way to get the sigcontext structure is by including <signal.h> (in a context where __USE_MISC is defined); the sysdeps/generic version of sys/ucontext.h keeps the inclusion by necessity, with a comment about how this is not namespace-clean, but the only configuration that used it, MicroBlaze, gets its own version of the header in this patch. Where mcontext_t was typedefed to struct sigcontext, the contents of struct sigcontext are inserted (with appropriate namespace handling to prefix fields with __ when __USE_MISC is not defined); review should check that this has been done correctly in each case, whether the definition of struct sigcontext comes from glibc headers or from the Linux kernel.

The cause of the problem is the use of `alloca' in regular MIPS/Linux wrappers to force the use of the frame pointer register in any function using one or more of these wrappers. Using the frame pointer register is required so as not to break frame unwinding as the the stack pointer is lowered within the inline asm used by these wrappers to make room for the stack arguments, which 5-, 6- and 7-argument syscalls use with the o32 ABI. The regular MIPS/Linux wrappers are macros however, expanded inline, and stack allocations made with `alloca' are not discarded until the return of the function they are made in. Consequently if called in a loop, then virtual memory is wasted, and if the loop goes through enough iterations, then ultimately available memory can get exhausted causing the program to crash. Address the issue by replacing the inline code with standalone assembly functions, which rely on the compiler arranging syscall arguments according to the o32 function calling convention, which MIPS/Linux syscalls also use, except for the syscall number passed and the error flag returned. This way there is no need to fiddle with the stack pointer anymore and all that has to be handled in the new standalone functions is the special handling of the syscall number and the error flag. Redirect 5-, 6- or 7-argument MIPS16/Linux syscall wrappers to these new functions as well, so as to avoid an unnecessary double call the existing wrappers would cause with the new arrangement.

*	[AArch64] Fix procfs.h not to expose stdint.h types	Szabolcs Nagy	2017-08-29	1	-2/+1
\| \| \| \| \| \| \|	Commit 39e7a5a66828a60008543db5f03f46dc7081668b added stdint.h to sys/procfs.h, but it is included into signal.h by default and there is code that does not expect stdint.h to be visible there, so use __uint64_t instead of uint64_t.
