--- Comment #18 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:c8b549857d968d634a74709112e5acc9f9caf35c commit r12-10895-gc8b549857d968d634a74709112e5acc9f9caf35c Author: Richard Biener <rguent...@suse.de> Date: Wed Jul 24 13:16:35 2024 +0200 tree-optimization/116057 - wrong code with CCP and vector CTORs The following fixes an issue with CCPs likely_value when faced with a vector CTOR containing undef SSA names and constants. This should be classified as CONSTANT and not UNDEFINED. PR tree-optimization/116057 * tree-ssa-ccp.cc (likely_value): Also walk CTORs in stmt operands to look for constants. * gcc.dg/torture/pr116057.c: New testcase. (cherry picked from commit 1ea551514b9c285d801ac5ab8d78b22483ff65af)
