--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:157af9d1ea36bbece6f871bdbd7758471dfb4e8f commit r16-9672-g157af9d1ea36bbece6f871bdbd7758471dfb4e8f Author: Richard Biener <[email protected]> Date: Tue Sep 15 10:52:22 2026 +0200 tree-optimization/127390 - vectorization of _BitInt comparisons We fail to reject vectorizing of comparisons of non-mode precision integer types. Those need to be dealt with via bitfield lowering in ifcvt or pattern recognition. PR tree-optimization/127390 * tree-vect-stmts.cc (vectorizable_comparison_1): Reject bit-precision integer comparisons. * gcc.dg/vect/vect-pr127390.c: New testcase. (cherry picked from commit faf5c056ca1826cffb5673fa3b445eb61a6bb7eb)
