2013-07-26PowerPC: use _dl_static_init to set GLRO(gl_pagesize)rsa/2.17_backports_v3Adhemerval Zanella5-0/+137
This patch fixes dlfcn/tststatic5 for PowerPC where pagesize variable was not properly initialized in certain cases. This patch is based on other architecture code. (cherry picked from commit 7b1f8b581f9387230788e4d8a67cdbcf464dac85)
2013-07-26Fix loop construction to functions callsAdhemerval Zanella9-0/+82
Check wheter the compiler has the option -fno-tree-loop-distribute-patterns to inhibit loop transformation to library calls and uses it on memset and memmove default implementation to avoid recursive calls. (backported from commit 85c2e6110c9a01ec817c30f1b7e20549d7229987) This backport excluded the benchmark tests from the original commit.

This patch reserves four pointer to be used in future Event-Based Branch framework for PowerPC. (cherry picked from commit e55a9b256d53c7fc5145e3e4d338d3741b23e232)
2013-07-26Fix unsafe compiler optimizationAdhemerval Zanella3-1/+16
GCC 4.8 enables -ftree-loop-distribute-patterns at -O3 by default and this optimization may transform loops into memset/memmove calls. Without proper handling this may generate unexpected PLT calls on GLIBC. This patch fixes by create memset/memmove alias to internal GLIBC __GI_memset/__GI_memmove symbols. (cherry picked from commit 6a97b62a5b4f18aea849d6f4d8de58d1469d2521)

2013-07-25PowerPC: Add time vDSO supportAdhemerval Zanella5-3/+81
PowerPC kernel now provides a vDSO implementation for time syscall (commit fcb41a2030abe0eb716ef0798035ef9562097f42). This patch changes time syscall wrapper to use the vDSO when available. It also changes the default non vDSO time on PowerPC to use sysdeps/posix/time.c (since gettimeofday is a vDSO call). (cherry picked from commit 83e7640f6bf68708ecf0b09d83c670203167271e)
2013-07-25PowerPC: modf optimization fixAdhemerval Zanella5-0/+14
This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits by correctly setting minimum architecture for modf PPC optimization to power5+ instead of power5 (since only on power5+ round/ceil will be inline to inline assembly). (cherry picked from commit aa630f590c9c7d070a7cdf3a2a88069ad6b63de9)
2013-07-25PowerPC: modf optimizationAdhemerval Zanella5-0/+118

2013-07-25PowerPC: remove branch prediction from rint implementationAdhemerval Zanella4-12/+12
The branch prediction hints is actually hurts performance in this case. The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52' is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a general floating point function, expected input is not bounded and then it is better to let the hardware handle the branches. (backported from commit 60c414c346a1d5ef0510ffbdc0ab75f288ee4d3f) This backport does not include the benchmark tests from the original commit.

2013-07-25Corrected ChangeLog date of __kernel_get_tbfreq fix.Ryan S. Arnold1-1/+1
(cherry picked from commit 90567f30eb334328ae6e2b7901df539f1ba61921)
2013-07-25PowerPC: Rename __kernel_vdso_get_tbfreq to __kernel_get_tbfreq.Anton Blanchard5-29/+55
In order for the __kernel_get_tbfreq vDSO call to work the INTERNAL_VSYSCALL_NCS macro needed to be updated to prevent it from assuming an integer return type (since the timebase frequency is a 64-bit value) by specifying the type of the return type as a macro parameter. The macro then specifically declares the return value as a 'register' (or implied pair) of the denoted type. The compiler is then informed that this register (or implied pair) is to be used for the return value. (cherry picked from commit 471a1672d4d55124de4db8273829f96cc14d424a)

2013-07-23tile BZ #15759: Fix bug in _dl_unmapChris Metcalf3-4/+16
We returned without calling __munmap if not in the simulator. Now we call a separate sim_dlclose() function to make the control flow work correctly. (cherry picked from commit 1fe2988f523ddbad93ca7abc98fea982f2ae0505) Conflicts: NEWS
2013-06-19tile: default to little-endian in bits/endian.hChris Metcalf2-3/+5
This turns out to be helpful when doing a from-scratch cross-compile of gcc and glibc, since you can then do "make install-headers" in glibc even before you have a functioning tile gcc. (cherry picked from commit ad36ba2bd67398edefe31aa039090912f76bffce)
2013-06-09tile: improve detection for missing -mcmodel=large supportChris Metcalf4-4/+41
The existing test avoided passing -mcmodel=large if the compiler didn't support it. However, we need to test not just the compiler support, but also the toolchain (as and ld) support, so make the test more complete. In addition, we have to avoid using the hwN_plt() assembly operators if that support is missing, so guard the uses with #ifdef NO_PLT_PCREL. This allows us to properly build glibc with the current community binutils, which doesn't yet have the PC-relative PLT operator support. The -mcmodel=large support is in gcc 4.8, but the toolchain support won't be present in the community until binutils 2.24. (cherry picked from commit 86bd05fbc8b3a635148f6a7d8b4fb89c9a524e58)
