            Bug ID: 97534
           Summary: [10/11 Regression] ICE in decompose, at rtl.h:2280
                    (arm-linux-gnueabihf)
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at debian dot org
  Target Milestone: ---

seen building mariadb with the gcc-10 branch and trunk, not seen without -g, or
with -O0:

$ cat btr0cu.ii
struct a {
  int b;
  void c(int d) { __atomic_fetch_sub(&b, d, int()); }
};
class e {
  a f;
  int g = 1 << 31;
  void h() { f.c(g); }
public:
  void i() {
    e j;
    j.h();
  }
} k;
void l() { k.i(); }

$ g++ -std=gnu++11 -c -g -O2 btr0cu.ii
during RTL pass: vartrack
btr0cu.ii: In function 'void l()':
btr0cu.ii:15:19: internal compiler error: in decompose, at rtl.h:2280
