Summary: ggc 9.2.0 failing openmp compile on ppc64le
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal

The minimal test-case C file i used.
Compiling the attached program with "gcc -fopenmp" failes with the following
error on my ppc64le platform:
---
$ gcc -fopenmp test-openmp.c
test-openmp.c: In function ‘testfunc’:
test-openmp.c:10:15: error: ‘*.LC0’ not specified in enclosing ‘parallel’
10 | float k[3] = { 0.1f, 0.1f, 0.1f } ;
| ^
test-openmp.c:7:9: error: enclosing ‘parallel’
7 | #pragma omp parallel for default(none) shared(f)
| ^~~

This errors does not appear if the 0.1f values are replaced with 0.0f in the
k[3] array.
