Noah Goldstein 2c9af8421d x86: Fix page cross case in rawmemchr-avx2 [BZ #29234] ... commit 6dcbb7d95d Author: Noah Goldstein <goldstein.w.n@gmail.com> Date: Mon Jun 6 21:11:33 2022 -0700 x86: Shrink code size of memchr-avx2.S Changed how the page cross case aligned string (rdi) in rawmemchr. This was incompatible with how `L(cross_page_continue)` expected the pointer to be aligned and would cause rawmemchr to read data start started before the beginning of the string. What it would read was in valid memory but could count CHAR matches resulting in an incorrect return value. This commit fixes that issue by essentially reverting the changes to the L(page_cross) case as they didn't really matter. Test cases added and all pass with the new code (and where confirmed to fail with the old code). Reviewed-by: H.J. Lu <hjl.tools@gmail.com>		2022-06-08 17:07:34 -07:00
