Bug ID: 105536
Summary: [OpenMP] Bogus "expected ‘concurrent’ before
‘reproducible’"
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: diagnostic, openmp
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
I think the message shown by C/C++ for the following is bogus:
repro.c:3:23: error: expected ‘concurrent’ before ‘reproducible’
3 | #pragma omp for order(reproducible)
| ^~~~~~~~~~~~
The standard requires 'order(reproducible:concurrent)' – Thus, I expect *after*
and not *before* in the error message.
Cf. https://www.openmp.org/spec-html/5.1/openmpsu47.html#x72-720002.11.3
void f(void)
{
#pragma omp for order(reproducible)
for (int i=0; i < 1; i++)
;
}
Side remark: Fortran is fine as it gives the following:
1 | !$omp do order(reproducible)
| 1
Error: Expected ORDER(CONCURRENT) at (1) with optional ‘reproducible’ or
‘unconstrained’ modifier
