            Bug ID: 100400
           Summary: ICE in visit_loops_in_gang_single_region
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: openacc
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: asolokha at gmx dot com
  Target Milestone: ---

g++-12.0.0-alpha20210502 snapshot (g:92f59e47f5a468b96b12b15233a6729904b1a1ee)
ICEs when compiling the following testcase, reduced from
libgomp/testsuite/libgomp.oacc-c-c++-common/kernels-decompose-1.c, w/ -O1
-fopenacc -g --param openacc-kernels=decompose:

int *p;

void
foo (void)
{
#pragma acc kernels
  {
    int c;

    p = &c;

#pragma acc loop independent
    for (c = 0; c < 1; ++c)
      ;
  }
}

% g++-12.0.0 -O1 -fopenacc -g --param openacc-kernels=decompose -c uupipzvt.c
during GIMPLE pass: omp_oacc_kernels_decompose
uupipzvt.c: In function 'void foo()':
