* Define __GI_fegetenv for e500 libmKhem Raj2014-09-021-0/+1
| | | | | | | | | | | generic HAVE_RM_CTX implementation which is used for ppc/e500 as well has introduced calls to fegetenv which should be resolved internally with in libm Signed-off-by: Khem Raj <raj.khem@gmail.com> * sysdeps/powerpc/powerpc32/e500/nofpu/fegetenv.c (fegetenv): Add libm_hidden_ver.
* Remove unnecessary uses of NOT_IN_libcSiddhesh Poyarekar2014-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a IS_IN_* macro is defined, then NOT_IN_libc is always defined, except obviously for IS_IN_libc. There's no need to check for both.

* PowerPC: Cleanup powerpc memmoveAdhemerval Zanella2014-07-083-2/+4
| | | | | | | Now that MEMCPY_OK_FOR_FWD_MEMMOVE should be define on memcopy.h there is no need to specialized powerpc memmove implementation. This patch moves the define set to powerpc memcopy and cleanup its definition on powerpc code.
* PowerPC: Fix compiler warningsAdhemerval Zanella2014-07-082-2/+2
| | | | | This patch fixes some compiler due trailing data in #undef directives and due missing prototypes.
* PowerPC: Add ifunc tests for memmoveAdhemerval Zanella2014-07-081-0/+6
| | | | | This patch add the missing ifunc tests definition for memmove ppc32 optimization patch (commit 07aedd7).
* PowerPC: Align power7 memcpy using VSX to quadwordAdhemerval Zanella2014-07-071-2/+2
| | | | | | This patch changes power7 memcpy to use VSX instructions only when memory is aligned to quardword. It is to avoid unaligned kernel traps on non-cacheable memory (for instance, memory-mapped I/O).
* PowerPC: optimized memmove for POWER7/PPC32Adhemerval Zanella2014-07-074-1/+100
| | | | | This patch adds a optimized memmove for power7 by using the optimized power7 memcpy for forward copying.

|
* Unify hp-timing implementationsRichard Henderson2014-07-031-53/+1
| | | | Provide an hp-timing-common.h for ports to use.
* Remove HP_TIMING_DIFF_INIT and dl_hp_timing_overheadRichard Henderson2014-07-032-48/+0
| | | | | Without HP_TIMING_ACCUM, dl_hp_timing_overhead is write-only. If we remove it, there's no point in HP_TIMING_DIFF_INIT either.
* Removing HP_TIMING_ACCUM as unusedRichard Henderson2014-07-031-16/+2

* Removing HP_TIMING_ZERO as unusedRichard Henderson2014-07-031-5/+0

* powerpc: Remove dummy hp-timing.hRichard Henderson2014-07-031-81/+0
| | | | It's the same as the generic dummy version.
* Fix Wundef warning for ELF_MACHINE_NO_RELASiddhesh Poyarekar2014-06-261-0/+1
| | | | | | | This patch defines ELF_MACHINE_NO_RELA on all architectures. Tested only on x86_64 to verify that the sources before and after are identical except for two instructions that pass the current line number in dl-machine.h to assert_fail.
* PowerPC: Remove 64 bits instructions in PPC32 codeAdhemerval Zanella2014-05-268-16/+16
| | | | This patch replaces the insrdi by insrwi in powerpc32 assembly.
* PowerPC: Fix memchr ifunc hidden symbol for PPC32Adhemerval Zanella2014-05-222-10/+14
| | | | | | | | | This patch fixes a similar issue to 736c304a1ab4cee36a2f3343f1698bc0abae4608, where for PPC32 if the symbol is defined as hidden (memchr) then compiler will create a local branc (symbol@local) and the linker will not create a required PLT call to make the ifunc work. It changes the default hidden symbol (__GI_memchr) to default memchr symbol for powerpc32 (__memchr_ppc32).
* PowerPC: ifunc improvement for internal callsAdhemerval Zanella2014-05-051-2/+1
| | | | | | | This patch changes de default symbol redirection for internal call of memcpy, memset, memchr, and strlen to the IFUNC resolved ones. The performance improvement is noticeable in algorithms that uses these symbols extensible, like the regex functions.
* PowerPC: Fix --disable-multi-arch buildsAdhemerval Zanella2014-04-091-0/+1
| | | | | | | | | | This patch fixes some powerpc32 and powerpc64 builds with --disable-multi-arch option along with different --with-cpu=powerN. It cleanups the Implies directories by removing the multiarch folder for non multiarch config and also fixing two assembly implementations: powerpc64/power7/strncat.S that is calling the wrong strlen; and power8/fpu/s_isnan.S that misses the hidden_def and weak_alias directives.
* PowerPC: Fix nearbyint/nearbyintf result for FE_DOWNWARDAdhemerval Zanella2014-04-062-10/+11
| | | | | | | | | This patch fixes the powerpc32 optimized nearbyint/nearbyintf bogus results for FE_DOWNWARD rounding mode. This is due wrong instructions sequence used in the rounding calculation (two subtractions instead of adition and a subtraction). Fixes BZ#16815.
* PowerPC: Fix bzero definition for static libc for PPC32Adhemerval Zanella2014-03-122-2/+11
| | | | | | | | | | This patch fixes an issue for powerpc32-fpu static build which fails with an 'bzero' undefined reference. This patch adds bzero ifunc selector for static builds and fixes the '__bzero_ppc' reference to default memset symbol (since static memset build does not provide ifunc selector). Fixes BZ#16689.
* PowerPC: Optimized isnan/isnanf for POWER8Adhemerval Zanella2014-02-271-0/+1
| | | | | | This patch add a optimized isnan/isnanf implementation for POWER8 using the new Move From VSR Doubleword instruction to gains some cycles from FP to GRP register move.

* Don't make soft-fp symbols compat symbols for powerpc-nofpu.Joseph Myers2013-12-191-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/powerpc/powerpc32/libgcc-compat.S makes certain symbols that glibc once accidentally reexported from libgcc into compat symbols. Where the exports were purely accidental, this is the right thing to do. However, for powerpc-nofpu the soft-fp symbols are deliberately exported from libc, given public versions in sysdeps/powerpc/nofpu/Versions and used by libm in preference to the libgcc versions that do not support the software exceptions and rounding modes. The libc versions should also be usable by user programs, though normally libgcc gets linked in first (meaning, effectively, that the <fenv.h> functions are broken as regards their expected effects on user arithmetic). A longstanding todo item is to remove the functions in question from libgcc (when built with recent enough glibc) - that is, remove them from static libgcc and make them compat symbols in shared libgcc - so that this works properly (this is one of the items mentioned at <http://gcc.gnu.org/wiki/Software_floating_point> - parts of that page are obviously out of date, but this item still applies). Doing this requires first that the functions are actually available from libc for new links, not just as compat symbols. This patch stops the symbols in question being compat symbols for powerpc-nofpu. The nofpu Versions entries for them are removed (the symbols never were exported at GLIBC_2.3.2, only GLIBC_2.0, because the compat symbols took precedence). Tested powerpc-nofpu. The symbols are no longer compat symbols and libm.so now properly gets undefined references to them (resolved to libc.so) instead of the libgcc copies getting linked into libm as before. * sysdeps/powerpc/powerpc32/libgcc-compat.S [_SOFT_FLOAT || __NO_FPRS__] (__fixdfdi_v_glibc20): Do not define as a macro and a compat symbol.
