            Bug ID: 80310
           Summary: [7 Regression] Bogus -Wpsabi warning with
                    -fsanitize=signed-integer-overflow
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

/* { dg-do compile } */
/* { dg-options "-O2 -fsanitize=signed-integer-overflow" } */
/* { dg-additional-options "-mno-avx" { target i?86-*-* x86_64-*-* } } */

typedef int V __attribute__((vector_size (32)));

void
foo (V *a, V *b, V *c)
{
  *a = *b + *c;         /* { dg-bogus "AVX vector return without AVX enabled
changes the ABI" "" { target i?86-*-* x86_64-*-* } } */
}

gets warning in 7+, even when there is no actual function that returns in AVX
registers.
