            Bug ID: 103804
           Summary: ICE: 'global_options' are modified in local context
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: asolokha at gmx dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---
            Target: powerpc-*-linux-gnu

gcc, at least configured for powerpc target and invoked w/ -mcpu= set to a
value valid to that target, ICEs when compiling testcases w/ explicitly wrong
(non-powerpc)
#pragrma GCC target ("")
statements and
__attribute__ ((optimize ()))
set on a function.

The following testcase was extracted from
gcc/testsuite/gcc.target/aarch64/vect-widen-add.c:

#pragma GCC target "+nosve"

#define ARR_SIZE 1024

__attribute__((optimize (0))) void
uadd_nonopt (unsigned int *foo, unsigned short int *a, unsigned short int *b)
{
    for( int i = 0; i < ARR_SIZE - 3;i=i+4)
    {
        foo[i]   = a[i]   + b[i];
        foo[i+1] = a[i+1] + b[i+1];
        foo[i+2] = a[i+2] + b[i+2];
        foo[i+3] = a[i+3] + b[i+3];
    }
}
