2015-05-11Fix mips16 __fpu_control static linking (bug 18397).Joseph Myers2-1/+4
Programs are supposed to be able to define the __fpu_control variable, overriding the library's version to cause the floating-point control word to be set to the chosen value at startup. This is broken for mips16 for static linking because the library's __fpu_control variable is in the same object file as the helper functions used by fpu_control.h for mips16, so test-fpucw-ieee-static fails to link with multiple definitions of __fpu_control. This patch fixes this by putting the helpers in a separate file rather than overriding fpu_control.c. Tested for mips16 that this fixes the link failure and the ABI tests still pass. [BZ #18397] * sysdeps/mips/mips32/fpu/fpu_control.c: Move to .... * sysdeps/mips/mips32/fpu/fpucw-helpers.c: ... here. Include <fpu_control.h> instead of <math/fpu_control.c>. * sysdeps/mips/mips32/fpu/Makefile: New file.

2015-02-16Fix MIPS _ABIO64 -Werror=undef build.Joseph Myers1-0/+4
I see an error ../sysdeps/mips/memcpy.S:209:68: error: "_ABIO64" is not defined [-Werror=undef] #if defined(_MIPS_SIM) && ((_MIPS_SIM == _ABIO32) || (_MIPS_SIM == _ABIO64)) ^ cc1: some warnings being treated as errors in MIPS builds. This patch arranges for _ABIO64 to be defined with the same value as GCC uses when building for O64 (the ABI itself isn't supported by glibc, but defining the macro seems the simplest way of avoiding the error in code that may be shared with other C libraries). * sysdeps/mips/sgidefs.h [!_ABIO64] (_ABIO64): New macro.
2015-02-16Fix MIPS _COMPILING_NEWLIB -Werror=undef build.Joseph Myers3-3/+3
I see an error ../sysdeps/mips/strcmp.S:25:7: error: "_COMPILING_NEWLIB" is not defined [-Werror=undef] #elif _COMPILING_NEWLIB ^ cc1: some warnings being treated as errors in MIPS builds. (This is with GCC 4.9; it's possible that the DR#412 change in GCC 5 - see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60570> - means that -Wundef diagnostics no longer occur for #elif conditions where a previous group's condition was true, just as with other errors there.) This patch duly adjusts the conditionals to test whether _COMPILING_NEWLIB is defined. * sysdeps/mips/memcpy.S [_COMPILING_NEWLIB]: Change condition to [defined _COMPILING_NEWLIB]. * sysdeps/mips/memset.S [_COMPILING_NEWLIB]: Likewise. * sysdeps/mips/strcmp.S [_COMPILING_NEWLIB]: Likewise.
2015-02-16Fix MIPS __mips_isa_rev -Werror=undef build.Joseph Myers1-1/+1
I see an error In file included from ../sysdeps/mips/include/sys/asm.h:20:0, from ../sysdeps/mips/start.S:39: ../sysdeps/mips/sys/asm.h:421:5: error: "__mips_isa_rev" is not defined [-Werror=undef] #if __mips_isa_rev < 6 ^ cc1: some warnings being treated as errors in MIPS builds. As sys/asm.h is an installed header, it seems better to test for !defined __mips_isa_rev here, instead of defining it to 0 as done in sysdeps/unix/mips/sysdep.h, to avoid perturbing any code outside glibc that tests whether __mips_isa_rev is defined; this patch does so. * sysdeps/mips/sys/asm.h [__mips_isa_rev < 6]: Change condition to [!defined __mips_isa_rev || __mips_isa_rev < 6].

2015-02-10Remove sysdeps/mips soft-fp subdirectories.Joseph Myers7-3/+0
As noted in <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, soft-fp sysdeps subdirectories (and more generally, subdirectories where sysdeps/foo/Implies contains foo/bar) are unnecessary and should be eliminated. This patch does so for MIPS. Tested for MIPS64 (all three ABIs, soft-float) that installed stripped shared libraries are unchanged by this patch. * sysdeps/mips/soft-fp/sfp-machine.h: Move to .... * sysdeps/mips/mips32/sfp-machine.h: ... here. * sysdeps/mips/mips64/soft-fp/Makefile: Move to .... * sysdeps/mips/mips64/Makefile: ... here. * sysdeps/mips/mips64/soft-fp/e_sqrtl.c: Move to .... * sysdeps/mips/mips64/e_sqrtl.c: ... here. * sysdeps/mips/mips64/soft-fp/sfp-machine.h: Move to .... * sysdeps/mips/mips64/sfp-machine.h: ... here. * sysdeps/mips/mips32/Implies: Remove mips/soft-fp. * sysdeps/mips/mips64/n32/Implies: Remove mips/mips64/soft-fp. * sysdeps/mips/mips64/n64/Implies: Likewise.
2015-01-28Disable 64-bit atomics for MIPS n32.Joseph Myers1-1/+1
This patch disables use of 64-bit atomics for MIPS n32 to fix the problems with unaligned semaphores. Before 64-bit atomics are used for anything for which such alignment issues do not arise, and before the addition of any new ILP32 ports with 64-bit semaphores for which the ABI can be set to have the greater alignment (AARCH64?), a better approach will need to be established that allows architectures to declare their 64-bit atomics availability accurately, without doing so causing inappropriate use of such atomics on unaligned semaphores. Tested for MIPS n32 that this fixes the nptl/tst-sem3 failure. * sysdeps/mips/bits/atomic.h [_MIPS_SIM == _ABIN32] (__HAVE_64B_ATOMICS): Define to 0.
2015-01-07Fix libm feupdateenv namespace (bug 17748).Joseph Myers1-2/+4

2014-12-30Fix libm feraiseexcept namespace (bug 17723).Joseph Myers2-3/+5
Various C90 and UNIX98 libm functions call feraiseexcept, which is not in those standards. This causes linknamespace test failures - except on x86 / x86_64, where feraiseexcept is inline (for the relevant constant arguments) in bits/fenv.h. This patch fixes this by making those functions call __feraiseexcept instead. All changes are applied to all architectures rather than considering the possibility that some might not be needed in some cases (e.g. x86) as it seems most maintainable to keep architectures consistent. Where __feraiseexcept does not exist, it is added, with feraiseexcept made a weak alias; where it is a strong alias, it is made weak. libm_hidden_def / libm_hidden_proto are used with __feraiseexcept (this might in some cases improve code generation for existing calls to __feraiseexcept in some code on some architectures). Where there are dummy feraiseexcept macros (on architectures without floating-point exceptions support, to avoid compile errors from references to undefined FE_* macros), corresponding dummy __feraiseexcept macros are added. And on x86, to ensure __feraiseexcept calls still get inlined, the inline function in bits/fenv.h is refactored so that most of it can be reused in an inline __feraiseexcept in a separate include/bits/fenv.h. Calls are changed in C90/UNIX98 functions, but generally not in functions missing from those standards. They are also changed in libc_fe* functions (on the basis that those might be used in any libm function), and in feupdateenv (on the same basis - may be used, via default libc_*, in any libm function - of course feupdateenv will need changing to __feupdateenv in a subsequent patch to make that fully namespace-clean). No __feraiseexcept is added corresponding to the feraiseexcept in powerpc bits/fenvinline.h, because that macro definition is conditional on !defined __NO_MATH_INLINES, and glibc libm is built with -D__NO_MATH_INLINES, so changing internal calls to use __feraiseexcept should make no difference. Tested for x86_64 (testsuite; the only change in disassembly of installed shared libraries is a slight code reordering in clog10, of no apparent significance). Also tested for MIPS, where (in the configuration tested) it eliminates math.h linknamespace failures for n32 and n64 (some for o32 remain because of other issues).

This patch fixes ../sysdeps/mips/__longjmp.c:27:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] which arose I think from the MIPS16 changes (renaming the function to ____longjmp with an alias __longjmp, so a prior header prototype for __longjmp no longer sufficed to prevent a warning). I've made the function use a prototype definition, which is what we want for all function definitions in glibc anyway. Tested for MIPS. * sysdeps/mips/__longjmp.c (____longjmp): Use prototype definition.

2014-11-04Don't use INTDEF/INTUSE with _dl_init (bug 14132).Joseph Myers1-4/+4
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch eliminates its use for _dl_init. Since _dl_init was already declared with hidden visibility, creating a second hidden alias for it was completely pointless, so this patch replaces all uses of _dl_init_internal with plain _dl_init instead of using hidden_proto / hidden_def (which are only needed when you want a hidden alias for a non-hidden symbol; it's quite possible there are cases where they are used but don't need to be because the symbol in question is not part of the public ABI and is only used within a single library, so using attributes_hidden instead would suffice). Tested for x86_64 that installed stripped shared libraries are unchanged by the patch.

2014-07-17Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2-26/+0
Various architectures have files such as sysdeps/<arch>/shlib-versions whose contents are in fact entirely Linux-specific, relating only to the symbol / shared library versions for the port to Linux on that architecture, when any future port to a different OS on that architecture would use the symbol version of the glibc release it goes in, as standard for new ports. This patch moves such files under sysdeps/unix/sysv/linux/, merging in the contents of sysdeps/<arch>/nptl/shlib-versions in the process. The only bits not moved are those relating to libgcc_s versions, which don't appear OS-specific in the same way that glibc's symbol versions so. It deliberately does not change the regular expressions given for matching configurations in each file; some match only Linux although not Linux-specific, or match other OSes although Linux-specific. It is with a view to at least the following further cleanups: * Move architecture-specific content from the toplevel shlib-versions and nptl/shlib-versions into sysdeps shlib-versions files, so eliminating another difference between ex-ports and non-ex-ports architectures. * Likewise, for OS-specific content in shlib-versions files. * At that point, the first field in shlib-versions files (the regular expression matching a configuration triplet) should be redundant, so eliminate that field and leave shlib-versions selection working purely on a sysdeps basis (with limited use of %ifdef in shlib-versions files when needed) rather than having its own separate mechanism to select what configuration information is relevant. * Move the build of gnu/lib-names.h to a similar mechanism to that used for gnu/stubs.h (each library build installing a version of the header specifically for that build), so we can eliminate the duplication of soname information in the makefiles and get it purely from shlib-versions files again. There may be other cleanups possible as well (in particular, I'm not sure that all cases where the same "Earliest symbol set" information is repeated for many different libraries actually should need to repeat it rather than specifying it just once for DEFAULT for the given configuration, and separately specifying any non-default choices of soname).

This patch fixes -Wundef warnings related to the _ABI* macros on MIPS. GCC predefines only the _ABI* macro related to the ABI actually in use, meaning that a conditional such as "#if _MIPS_SIM == _ABI64" is true only for the ABI in question (all the macros are nonzero), but produces a -Wundef warning for the other ABIs. The normal approach to using these macros is to include <sgidefs.h>, which ensures that all three _ABI* macros are defined rather than just one; this patch does so in the places that caused warnings (the bulk of the warnings arising from <bits/wordsize.h>). Tested that the warnings are fixed. * sysdeps/mips/bits/wordsize.h: Include <sgidefs.h>. * sysdeps/unix/sysv/linux/mips/getrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/mips/setrlimit64.c: Likewise.

2014-03-11Fix MIPS libc_feresetround*_ctx to preserve exceptions.Joseph Myers1-10/+3
Testing on mips64 showed missing underflow exceptions (from exp, for example) in non-default rounding modes, caused by libc_feresetround*_ctx wrongly restoring a saved environment without preserving exceptions, when that's only valid for the _noex variants. (I don't know why Steve didn't see this in his testing.) This patch fixes this by using libc_feupdateenv_mips_ctx for the relevant macros and removing the problem definitions. The problem definitions aren't suitable for the _noex macros either because they only discard exceptions in non-default rounding modes, and while for some uses of *_noex/*_NOEX it doesn't matter whether exceptions are discarded, dbl-64/e_remainder.c requires SET_RESTORE_ROUND_NOEX to cause exceptions to be discarded. I think the accumulated set of macros / functions for optimized exception / rounding mode handling could do with a careful review by now, and possible refactoring, and at least one new feature (extracting the saved rounding mode from an environment / context variable - see dbl-64/e_sqrt.c for a case where this could be used).
