            Bug ID: 100767
           Summary: arm: ice when inlining at -flto with different cpu and
                    arch settings
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rearnsha at gcc dot gnu.org
  Target Milestone: ---

reproducer:

gcc -O -c -march=armv8-a+simd -flto t1.c
gcc -O -c -mcpu=native -flto main.c
gcc -flto -o main main.o t1.o

Where t1.c is

int f() { return 1;}

and main.c is

int f(void);
int main() { return f(); }

Results in calling strcmp with a NULL argument.  The problem starts in
arm_can_inline_p.
