Bug ID: 71065
Summary: Missing diagnostic for statements between OpenMP
'target' and 'teams'
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Keywords: accepts-invalid, openmp
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: amonakov at gcc dot gnu.org
Target Milestone: ---
OpenMP 4.5 says (4.0 had a similar restriction, sans 'declarations'):
If specified, a teams construct must be contained within a target construct.
That target construct must contain no statements, declarations or directives
outside of the teams construct.
As a result GCC should reject this:
void f()
{
#pragma omp target
{
asm("");
#pragma omp teams
;
}
}
(as I understand, 'if' clause on the 'target' pragma allows the user to run
their code in the target region prior to entering 'teams' region anyway, but
still diagnosing the above should be useful)
