These tests FAIL on i686-linux, with .../gcc/testsuite/gcc.dg/pr110915-1.c:8:1: warning: MMX vector return without MMX enabled changes the ABI [-Wpsabi] .../gcc/testsuite/gcc.dg/pr110915-1.c:7:15: warning: MMX vector argument without MMX enabled changes the ABI [-Wpsabi] excess warnings. I've added -Wno-psabi to quiet that up, plus I think it is undesirable to define macros like vector before including C library headers in case the header would use that identifier in non-obfuscated form somewhere. Tested with make check-g++ RUNTESTFLAGS='--target_board=unix\{-m32,-m32/-march=i686,-m64\} dg.exp=vectcond-1.C' on x86_64-linux which previously FAILed, committed to trunk as obvious. 2023-09-01 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/19832 * g++.dg/opt/vectcond-1.C: Add -Wno-psabi to dg-options. --- gcc/testsuite/g++.dg/opt/vectcond-1.C.jj 2023-09-01 12:15:36.072430927 +0200 +++ gcc/testsuite/g++.dg/opt/vectcond-1.C 2023-09-01 14:20:22.688739458 +0200 @@ -1,5 +1,5 @@ /* { dg-do compile } */ -/* { dg-options "-O2 -fdump-tree-ccp1 -fdump-tree-optimized" } */ +/* { dg-options "-O2 -fdump-tree-ccp1 -fdump-tree-optimized -Wno-psabi" } */ /* This is the vector version of these optimizations. */ /* PR tree-optimization/19832 */ Jakub
