https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98928 --- Comment #7 from CVS Commits --- The master branch has been updated by Tamar Christina : https://gcc.gnu.org/g:5e606ed90a1bed878071b6b5a3ef9b97b3d99838 commit r11-7049-g5e606ed90a1bed878071b6b5a3ef9b97b3d99838 Author: Tamar Christina Date: Wed Feb 3 08:06:11 2021 + slp: Split out patterns away from using SLP_ONLY into their own flag Previously the SLP pattern matcher was using STMT_VINFO_SLP_VECT_ONLY as a way to dissolve the SLP only patterns during SLP cancellation. However it seems like the semantics for STMT_VINFO_SLP_VECT_ONLY are slightly different than what I expected. Namely that the non-SLP path can still use a statement marked STMT_VINFO_SLP_VECT_ONLY. One such example is masked loads which are used both in the SLP and non-SLP path. To fix this I now introduce a new flag STMT_VINFO_SLP_VECT_ONLY_PATTERN which is used only by the pattern matcher. gcc/ChangeLog: PR tree-optimization/98928 * tree-vect-loop.c (vect_analyze_loop_2): Change STMT_VINFO_SLP_VECT_ONLY to STMT_VINFO_SLP_VECT_ONLY_PATTERN. * tree-vect-slp-patterns.c (complex_pattern::build): Likewise. * tree-vectorizer.h (STMT_VINFO_SLP_VECT_ONLY_PATTERN): New. (class _stmt_vec_info): Add slp_vect_pattern_only_p. gcc/testsuite/ChangeLog: PR tree-optimization/98928 * gcc.target/i386/pr98928.c: New test.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98928 --- Comment #5 from Tamar Christina --- Hmm looks like the SLP unwinding code is accidentally cancelling a pattern it shouldn't have. Checking why...
