Bug ID: 125367
Summary: [OpenMP] Missing diagnostic for list item in both map
and private clauses
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: parras at gcc dot gnu.org
Target Milestone: ---
Consider the following source code:
void f() {
int x, y;
#pragma omp target private(y) map(tofrom:x,y)
;
#pragma omp target firstprivate(x) map(tofrom:x,y)
;
}
This gives the two expected errors for both PRIVATE and FIRSTPRIVATE:
error: 'y' appears both in data and map clauses
3 | #pragma omp target private(y) map(tofrom:x,y)
| ^
error: 'x' appears both in data and map clauses
5 | #pragma omp target firstprivate(x) map(tofrom:x,y)
| ^
However, if we reverse the order of clauses:
void f() {
int x, y;
#pragma omp target map(tofrom:x,y) private(y)
;
#pragma omp target map(tofrom:x,y) firstprivate(x)
;
}
Then we only get the error for FIRSTPRIVATE:
error: ‘x’ appears both in data and map clauses
5 | #pragma omp target map(tofrom:x,y) firstprivate(x)
The error for PRIVATE is missing.
