Bug ID: 90456
Summary: OpenMP rejection: ‘ind1’ not specified in enclosing
‘parallel’ since r265930
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Following has been reduced from libimagequant package:
$ cat mediancut.i
typedef struct {
struct {
int sort_value;
} tmp;
} hist_item;
typedef struct {
int chan;
} channelvariance;
int prepare_sort_b_0;
double fn1() {
hist_item *achv;
channelvariance channels;
const int ind1 = prepare_sort_b_0;
#pragma omp parallel default(none) shared(achv, channels)
{
float *chans = (float *)&achv;
achv[ind1].tmp.sort_value = chans[channels.chan];
}
return 2;
}
$ gcc mediancut.i -fopenmp -c
mediancut.i: In function ‘fn1’:
mediancut.i:17:9: error: ‘ind1’ not specified in enclosing ‘parallel’
17 | achv[ind1].tmp.sort_value = chans[channels.chan];
| ^
mediancut.i:14:9: error: enclosing ‘parallel’
14 | #pragma omp parallel default(none) shared(achv, channels)
| ^~~
While GCC 8 accepts that:
$ gcc-8 --version
gcc-8 (SUSE Linux) 8.3.1 20190226 [gcc-8-branch revision 269204]
