--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Avinash Jayakar <[email protected]>: https://gcc.gnu.org/g:7d966cc35ad01d70cd9bfb6f531c938a7b6110b7 commit r16-5097-g7d966cc35ad01d70cd9bfb6f531c938a7b6110b7 Author: Avinash Jayakar <[email protected]> Date: Sat Nov 8 09:57:59 2025 +0530 isel: Check bounds before converting VIEW_CONVERT to VEC_SET. The function gimple_expand_vec_set_expr in the isel pass, converted VIEW_CONVERT_EXPR to VEC_SET_EXPR without checking the bounds on the index, which cause ICE on targets that supported VEC_SET_EXPR like x86 and powerpc. This patch adds a bound check on the index operand and rejects the conversion if index is out of bound. 2025-11-08 Avinash Jayakar <[email protected]> gcc/ChangeLog: PR tree-optimization/122126 * gimple-isel.cc (gimple_expand_vec_set_extract_expr): Add bound check. gcc/testsuite/ChangeLog: PR tree-optimization/122126 * gcc.dg/pr122126_vextr.c: New test. * gcc.dg/pr122126_vset.c: New test.
