--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by hongtao Liu <liuho...@gcc.gnu.org>: https://gcc.gnu.org/g:1bfe7e5352d1f4ac525317454aca45aa80a517ba commit r14-2086-g1bfe7e5352d1f4ac525317454aca45aa80a517ba Author: liuhongt <hongtao....@intel.com> Date: Sun Jun 25 11:12:29 2023 +0800 Use cvt_op to save intermediate type operand instead of "subtle" vec_dest. When there're multiple operands in vec_oprnds0, vec_dest will be overwrited to vectype_out, but in multi_step_cvt case, cvt_type is expected. It caused an ICE when verify_gimple_in_cfg. gcc/ChangeLog: PR tree-optimization/110371 PR tree-optimization/110018 * tree-vect-stmts.cc (vectorizable_conversion): Use cvt_op to save intermediate type operand instead of "subtle" vec_dest for case NONE. gcc/testsuite/ChangeLog: * gcc.target/aarch64/pr110371.c: New test.
