| * | x86: Add support to build strcmp/strlen/strchr with explicit ISA level | Noah Goldstein | 2022-07-16 | 1 | -1/+28 |
| | | | | | | | | | | | | | | | | | | | | | 1. Add default ISA level selection in non-multiarch/rtld implementations. 2. Add ISA level build guards to different implementations. - I.e strcmp-avx2.S which is ISA level 3 will only build if compiled ISA level <= 3. Otherwise there is no reason to include it as we will always use one of the ISA level 4 implementations (strcmp-evex.S). 3. Refactor the ifunc selector and ifunc implementation list to use the ISA level aware wrapper macros that allow functions below the compiled ISA level (with a guranteed replacement) to be skipped. Tested with and without multiarch on x86_64 for ISA levels: {generic, x86-64-v2, x86-64-v3, x86-64-v4} And m32 with and without multiarch. | ||||
| * | x86: Move strcmp SSE2 implementation to multiarch/strcmp-sse2.S | Noah Goldstein | 2022-07-13 | 1 | -3/+4 |
| | | | | | | | | | | | | | This commit doesn't affect libc.so.6, its just housekeeping to prepare for adding explicit ISA level support. Because strcmp-sse2.S implements so many functions (more from avx2/evex/sse42) add a new file 'strcmp-naming.h' to assist in getting the correct symbol name for all the function across multiarch/non-multiarch builds. Tested build on x86_64 and x86_32 with/without multiarch. | ||||
