--- Comment #21 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Torbjorn Svensson <[email protected]>: https://gcc.gnu.org/g:155193b2697facd1e84b34c5959345d9160cf34b commit r15-11397-g155193b2697facd1e84b34c5959345d9160cf34b Author: Torbjörn SVENSSON <[email protected]> Date: Tue Jul 14 10:22:06 2026 +0200 testsuite: arm: xfail predcom-8.c test in hard float without MVE [PR118407] In r15-6807-g68326d5d1a593d, more early break loops were vectorized. This change causes the test to fail: $ arm-none-eabi-gcc gcc.dg/tree-ssa/predcom-8.c \ -mthumb -march=armv7ve+neon -mtune=cortex-a7 -mfloat-abi=hard -mfpu=auto \ -O3 -fdump-tree-pcom-details-blocks -S -o predcom-8.s && grep "Invalid sum" predcom-8.*.pcom ;; Invalid sum of incoming counts 267993001 (estimated locally, freq 2.3331), should be 234459439 (estimated locally, freq 2.0412) ;; Invalid sum of incoming counts 31724316 (estimated locally, freq 0.2762), should be 78153146 (estimated locally, freq 0.6804) ;; Invalid sum of incoming counts 37162368 (estimated locally, freq 0.3235), should be 67298542 (estimated locally, freq 0.5859) ;; Invalid sum of incoming counts 487993506 (estimated locally, freq 4.2485), should be 471089795 (estimated locally, freq 4.1013) ;; Invalid sum of incoming counts 140991263 (estimated locally, freq 1.2275), should be 114863531 (estimated locally, freq 1.0000) The failures only happens for non-MVE targets in hard float ABI, thus xfail test for these targets. gcc/testsuite/ChangeLog: PR testsuite/118407 * gcc.dg/tree-ssa/predcom-8.c: Xfail test for arm*-*-* in hard float ABI without MVE.
