            Bug ID: 99787
           Summary: ICE in curr_insn_transform, at lra-constraints.c:4133
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-linux-gnu
            Target: aarch64-linux-gnu

I see the following ICE:

$ cat big.c
_Complex foo_x_0;
int foo_n11, foo_i, foo_l;
_Complex float foo_s;
_Complex *foo_f_0_0_0;

void
foo() {
  _Complex f[foo_l];
  for (; foo_i; foo_i++) {
    int n9;
    for (; n9 < foo_l; n9++)
      for (; foo_n11; foo_n11++)
        foo_s += foo_f_0_0_0[n9] * 0 * foo_f_0_0_0[foo_n11];
    foo_x_0 += foo_s;
  }
}

$ aarch64-linux-gnu-gcc big.c -O2 -ftree-slp-vectorize -ffp-contract=on
-ffloat-store -c
big.c: In function ‘foo’:
