* elf: Remove prelink supportAdhemerval Zanella2022-02-101-27/+21
| | | | | | | | | | | | | Prelinked binaries and libraries still work, the dynamic tags DT_GNU_PRELINKED, DT_GNU_LIBLIST, DT_GNU_CONFLICT just ignored (meaning the process is reallocated as default). The loader environment variable TRACE_PRELINKING is also removed, since it used solely on prelink. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.

* x86-64: Optimize bzeroH.J. Lu2022-02-0810-25/+256
| | | | | | | | | | memset with zero as the value to set is by far the majority value (99%+ for Python3 and GCC). bzero can be slightly more optimized for this case by using a zero-idiom xor for broadcasting the set value to a register (vector or GPR).

* x86: Remove SSSE3 instruction for broadcast in memset.S (SSE2 Only)Noah Goldstein2022-02-071-3/+4
| | | | | | | | | | | 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.
* x86: Improve vec generation in memset-vec-unaligned-erms.SNoah Goldstein2022-02-065-87/+152
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

* x86: Fix __wcsncmp_evex in strcmp-evex.S [BZ# 28755]Noah Goldstein2022-01-101-0/+10
| | | | | | | | | | Fixes [BZ# 28755] for wcsncmp by redirecting length >= 2^56 to __wcscmp_evex. For x86_64 this covers the entire address range so any length larger could not possibly be used to bound `s1` or `s2`. test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass.

* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-011086-1088/+1088
| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
