*	sparc: Remove optimize md5, sha256, and sha512	Adhemerval Zanella	2023-10-30	1	-8/+0
\| \| \| \| \| \| \| \| \| \|	The libcrypt was maked to be phase out on 2.38, and a better project already exist that provide both compatibility and better API (libxcrypt). The sparc optimizations add the burden to extra build-many-glibcs.py configurations. Checked on sparc64 and sparcv9. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
*	sparc: M7 optimized memset/bzero	Patrick McGehearty	2017-12-14	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Support added to identify Sparc M7/T7/S7/M8/T8 processor capability. Performance tests run on Sparc S7 using new code and old niagara4 code. Optimizations for memset also apply to bzero as they share code. For memset/bzero, performance comparison with niagara4 code: For memset nonzero data, 256-1023 bytes - 60-90% gain (in cache); 5% gain (out of cache) 1K+ bytes - 80-260% gain (in cache); 40-80% gain (out of cache) For memset zero data (and bzero), 256-1023 bytes - 80-120% gain (in cache), 0% gain (out of cache) 1024+ bytes - 2-4x gain (in cache), 10-35% gain (out of cache) Tested in sparcv9-- and sparc64-- targets in both multi and non-multi arch configurations. Patrick McGehearty <patrick.mcgehearty@oracle.com> Adhemerval Zanella <adhemerval.zanella@linaro.org> * sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile (sysdeps_routines): Add memset-niagara7. * sysdeps/sparc/sparc64/multiarch/Makefile (sysdes_rotuines): Likewise. * sysdeps/sparc/sparc32/sparcv9/multiarch/memset-niagara7.S: New file. * sysdeps/sparc/sparc64/multiarch/memset-niagara7.S: Likewise. * sysdeps/sparc/sparc64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add __bzero_niagara7 and __memset_niagara7. * sysdeps/sparc/sparc64/multiarch/ifunc-memset.h (IFUNC_SELECTOR): Add niagara7 option. * NEWS: Mention sparc m7 optimized memcpy, mempcpy, memmove, and memset.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Support added to identify Sparc M7/T7/S7/M8/T8 processor capability. Performance tests run on Sparc S7 using new code and old niagara4 code. Optimizations for memcpy also apply to mempcpy and memmove where they share code. Optimizations for memset also apply to bzero as they share code. For memcpy/mempcpy/memmove, performance comparison with niagara4 code: Long word aligned data 0-127 bytes - minimal changes 128-1023 bytes - 7-30% gain 1024+ bytes - 1-7% gain (in cache); 30-100% gain (out of cache) Word aligned data 0-127 bytes - 50%+ gain 128-1023 bytes - 10-200% gain 1024+ bytes - 0-15% gain (in cache); 5-50% gain (out of cache) Unaligned data 0-127 bytes - 0-70%+ gain 128-447 bytes - 40-80%+ gain 448-511 bytes - 1-3% loss 512-4096 bytes - 2-3% gain (in cache); 0-20% gain (out of cache) 4096+ bytes - ± 3% (in cache); 20-50% gain (out of cache) Tested in sparcv9-- and sparc64-- targets in both multi and non-multi arch configurations.
