2022-02-07x86: Remove SSSE3 instruction for broadcast in memset.S (SSE2 Only)Noah Goldstein
commit b62ace2740a106222e124cc86956448fa07abf4d Author: Noah Goldstein <goldstein.w.n@gmail.com> Date: Sun Feb 6 00:54:18 2022 -0600 x86: Improve vec generation in memset-vec-unaligned-erms.S Revert usage of 'pshufb' in broadcast logic as it is an SSSE3 instruction and memset.S is restricted to only SSE2 instructions.

Put one bench per line and sort them.
2022-02-06Benchtests: Add length zero benchmark for memset in bench-memset.cNoah Goldstein
Zero is a relevant size for some workloads (roughly 5% of uses for GCC) so we should be testing it's performance as well. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
2022-02-06x86: Improve vec generation in memset-vec-unaligned-erms.SNoah Goldstein
No bug. Split vec generation into multiple steps. This allows the broadcast in AVX2 to use 'xmm' registers for the L(less_vec) case. This saves an expensive lane-cross instruction and removes the need for 'vzeroupper'. For SSE2 replace 2x 'punpck' instructions with zero-idiom 'pxor' for byte broadcast. Results for memset-avx2 small (geomean of N = 20 benchset runs). size, New Time, Old Time, New / Old 0, 4.100, 3.831, 0.934 1, 5.074, 4.399, 0.867 2, 4.433, 4.411, 0.995 4, 4.487, 4.415, 0.984 8, 4.454, 4.396, 0.987 16, 4.502, 4.443, 0.987 All relevant string/wcsmbs tests are passing.

2022-02-03x86: Optimize strcmp-evex.SNoah Goldstein
Optimization are primarily to the loop logic and how the page cross logic interacts with the loop. The page cross logic is at times more expensive for short strings near the end of a page but not crossing the page. This is done to retest the page cross conditions with a non-faulty check and to improve the logic for entering the loop afterwards. This is only particular cases, however, and is general made up for by more than 10x improvements on the transition from the page cross -> loop case. The non-page cross cases as well are nearly universally improved. test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass. Signed-off-by: Noah Goldstein <goldstein.w.n@gmail.com>

The test changes the current foreground process group, which might break testing depending of how the make check is issued. For instance: nohup make -j1 test t=posix/tst-spawn6 | less Will set 'make' and 'less' to be in the foreground process group in the current session. When tst-spawn6 new child takes over it becomes the foreground process and 'less' is stopped and backgrounded which interrupts the 'make check' command. To fix it a pseudo-terminal is allocated, the test starts in new session (so there is no controlling terminal associated), and the pseudo-terminal is set as the controlling one (similar to what login_tty does).
