* | powerpc: Optimized stpcpy for POWER9 | Anton Blanchard via Libc-alpha | 2020-05-18 | 1 | -15/+58 |
| | | | | | | | | | | Add stpcpy support to the POWER9 strcpy. This is up to 40% faster on small strings and up to 90% faster on long relatively unaligned strings, compared to the POWER8 version. A few examples: __stpcpy_power9 __stpcpy_power8 Length 20, alignments in bytes 4/ 4: 2.58246 4.8788 Length 1024, alignments in bytes 1/ 6: 24.8186 47.8528 | ||||

This version uses VSX store vector with length instructions and is significantly faster on small strings and relatively unaligned large strings, compared to the POWER8 version. A few examples: __strcpy_power9 __strcpy_power8 Length 16, alignments in bytes 0/ 0: 2.52454 4.62695 Length 412, alignments in bytes 4/ 0: 11.6 22.9185 |
