--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Stefan Schulze Frielinghaus <stefa...@gcc.gnu.org>: https://gcc.gnu.org/g:417c36cfd620bf2b047852c2aa9ac49004aed2bc commit r11-8186-g417c36cfd620bf2b047852c2aa9ac49004aed2bc Author: Stefan Schulze Frielinghaus <stefa...@linux.ibm.com> Date: Thu Apr 15 08:03:47 2021 +0200 re PR tree-optimization/93210 (Sub-optimal code optimization on struct/combound constexpr (gcc vs. clang)) Regarding test gcc.dg/pr93210.c, on different targets GIMPLE code may slightly differ which is why the scan-tree-dump-times directive may fail. For example, for a RETURN_EXPR on x86_64 we have return 0x11100f0e0d0c0a090807060504030201; whereas on IBM Z the first operand is a RESULT_DECL like <retval> = 0x102030405060708090a0c0d0e0f1011; return <retval>; gcc/testsuite/ChangeLog: * gcc.dg/pr93210.c: Adapt regex in order to also support a RESULT_DECL as an operand for a RETURN_EXPR.
