* x86-64: Implement memmove family IFUNC selectors in CH.J. Lu2017-06-141-75/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement memmove family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. For libc.a, we can't use IFUNC for functions which are called before IFUNC has been initialized. Use IFUNC internally reduces the icache footprint since libc.so and other codes in the process use the same implementations. This patch uses IFUNC for memmove family functions within libc. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add memmove-sse2-unaligned-erms, memcpy_chk-nonshared, mempcpy_chk-nonshared and memmove_chk-nonshared. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add tests for __memmove_chk_erms, __memcpy_chk_erms and __mempcpy_chk_erms.

* x86: Use AVX2 memcpy/memset on Skylake server [BZ #21396]H.J. Lu2017-04-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Skylake server, AVX512 load/store instructions in memcpy/memset may lead to lower CPU turbo frequency in certain situations. Use of AVX2 in memcpy/memset has been observed to have improved overall performance in many workloads due to the higher frequency. Since AVX512ER is unique to Xeon Phi, this patch sets Prefer_No_AVX512 if AVX512ER isn't available so that AVX2 versions of memcpy/memset are used on Skylake server. [BZ #21396] * sysdeps/x86/cpu-features.c (init_cpu_features): Set Prefer_No_AVX512 if AVX512ER isn't available. * sysdeps/x86/cpu-features.h (bit_arch_Prefer_No_AVX512): New.

* Require binutils 2.24 to build x86-64 glibc [BZ #20139]H.J. Lu2016-07-011-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If assembler doesn't support AVX512DQ, _dl_runtime_resolve_avx is used to save the first 8 vector registers, which only saves the lower 256 bits of vector register, for lazy binding. When it is called on AVX512 platform, the upper 256 bits of ZMM registers are clobbered. Parameters passed in ZMM registers will be wrong when the function is called the first time. This patch requires binutils 2.24, whose assembler can store and load ZMM registers, to build x86-64 glibc. Since mathvec library needs assembler support for AVX512DQ, we disable mathvec if assembler doesn't support AVX512DQ. [BZ #20139] * config.h.in (HAVE_AVX512_ASM_SUPPORT): Renamed to ...

No change in IFUNC selection if SSE2 and AVX2 memcpy/memmove weren't used before. If SSE2 or AVX2 memcpy/memmove were used, the new SSE2 or AVX2 memcpy/memmove optimized with Enhanced REP MOVSB will be used for processors with ERMS. The new AVX512 memcpy/memmove will be used for processors with AVX512 which prefer vzeroupper. Since the new SSE2 memcpy/memmove are faster than the previous default memcpy/memmove used in libc.a and ld.so, we also remove the previous default memcpy/memmove and make them the default memcpy/memmove, except that non-temporal store isn't used in ld.so. Together, it reduces the size of libc.so by about 6 KB and the size of ld.so by about 2 KB.

* Improve 64bit memcpy performance for Haswell CPU with AVX instructionLing Ma2014-07-301-0/+4
| | | | | | | | | In this patch we take advantage of HSW memory bandwidth, manage to reduce miss branch prediction by avoiding using branch instructions and force destination to be aligned with avx instruction. The CPU2006 403.gcc benchmark indicates this patch improves performance from 2% to 10%.

* Faster memcpy on x64.Ondrej Bilka2013-05-201-7/+8
| | | | | | | | | We add new memcpy version that uses unaligned loads which are fast on modern processors. This allows second improvement which is avoiding computed jump which is relatively expensive operation. Tests available here: http://kam.mff.cuni.cz/~ondra/memcpy_profile_result27_04_13.tar.bz2

* Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7H.J. Lu2010-06-301-0/+73
This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and Core i7. It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and up to 1X on Core i7. It also improves memmove by up to 3X on Atom, up to 4X on Core 2 and up to 2X on Core i7.
