--- Comment #20 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Kewen Lin <[email protected]>: https://gcc.gnu.org/g:7bce1c72444bb3c9636b492975a0494b376678cf commit r9-8507-g7bce1c72444bb3c9636b492975a0494b376678cf Author: Kewen Lin <[email protected]> Date: Fri Apr 3 02:10:08 2020 -0500 Fix PR94443 with gsi_insert_seq_before [PR94443] This patch is to fix the stupid mistake by using gsi_insert_seq_before instead of gsi_insert_before. BTW, the regression testing on one x86_64 machine from CFarm is unable to reveal it (I guess due to native arch sandybridge?), so I specified additional option -march=znver2 and verified the coverage. Bootstrapped/regtested on powerpc64le-linux-gnu (P9) and x86_64-pc-linux-gnu, also verified the fail cases in related PRs. Backport from mainline. 2020-04-03 Kewen Lin <[email protected]> gcc/ PR tree-optimization/94443 * tree-vect-loop.c (vectorizable_live_operation): Use gsi_insert_seq_before to replace gsi_insert_before. gcc/testsuite/ PR tree-optimization/94443 * gcc.dg/vect/pr94443.c: New test.
