APAR status
Closed as program error.
Error description
When compiling an OMP for loop with mismatched loop counter datatypes, the OMP syntax check is being too strict and outputing an error. ===== TEST CASE ===== int main() { long var=0; #pragma omp parallel for schedule(static) for(int i1=0; i1<var; i1++) {} } $ xlc_r reduce.c -qsmp=omp -q64 "reduce.c", line 5.23: 1506-818 (S) Controlling expression of the for loop is not in the canonical form.
Local fix
Move the loop counter variable declaration outside of the for loop. This will change the variable promotion rules and work around the issue.
Problem summary
PROBLEM DESCRIPTION: The compiler is issuing a severe error for a 'for' loop not in OMP canonical form when using -q64, but the C standard allows it. USERS AFFECTED: Users using different integral types and sign with loop variable in a 'for' loop at 64bit.
Problem conclusion
Confirmed that the OMP form should not be more restrictive than the C standard. The check was relaxed, and mixed integral types are now allowed.
Temporary fix
