--- Comment #8 from Jan Hubicka <hubicka at ucw dot cz> --- > > FAIL: gcc.dg/ipa/ipa-cp-1.c scan-ipa-dump cp "Alignment 2" > FAIL: gcc.dg/ipa/ipa-cp-2.c scan-ipa-dump cp "Alignment 8, misalignment 4" Sorry, these was unintentinal commits, I will revert them soon. > FAIL: gcc.dg/noreturn-7.c (test for warnings, line 30) Here we do merging before outputting a warning (testcase expects two warnings). I suppose there is not much to do than -fno-ipa-cp. Once user adds one noreturn, he will get warning for anohter, because the functions will no longer get merged. > FAIL: gcc.target/i386/stackalign/longlong-2.c -mno-stackrealign > scan-assembler-times and[lq]?[^\\n]*-16,[^\\n]*sp 2 > FAIL: gcc.target/i386/stackalign/longlong-2.c -mno-stackrealign > scan-assembler-times and[lq]?[^\\n]*-8,[^\\n]*sp 2 > FAIL: gcc.target/i386/stackalign/longlong-2.c -mstackrealign > scan-assembler-times and[lq]?[^\\n]*-16,[^\\n]*sp 2 > FAIL: gcc.target/i386/stackalign/longlong-2.c -mstackrealign > scan-assembler-times and[lq]?[^\\n]*-8,[^\\n]*sp 2 I suppose here we merge void f2 (void) { unsigned long long a __attribute__((aligned (8))); fn (&a); } and void f4 (void) { unsigned long long a __attribute__((aligned (16))); fn (&a); } I already discussed with Martin yesterday that we need to compare alignments. I think he has patch on a way Honza
