When expanding a combined parallel+workshare region, the call to
the child function may need additional arguments in the case of
- OMP_FOR regions. In some cases, these arguments are computed out
- of variables passed in from the parent to the child via 'struct
- .omp_data_s'. For instance:
+ GIMPLE_OMP_FOR regions. In some cases, these arguments are
+ computed out of variables passed in from the parent to the child
+ via 'struct .omp_data_s'. For instance:
#pragma omp parallel for schedule (guided, i * 4)
for (j ...)
# BLOCK 2 (PAR_ENTRY_BB)
.omp_data_o.i = i;
#pragma omp parallel [child fn: bar.omp_fn.0 ( ..., D.1598)
-
+
# BLOCK 3 (WS_ENTRY_BB)
.omp_data_i = &.omp_data_o;
D.1667 = .omp_data_i->i;
To see whether the code in WS_ENTRY_BB blocks the combined
parallel+workshare call, we collect all the variables used in the
- OMP_FOR header check whether they appear on the LHS of any
+ GIMPLE_OMP_FOR header check whether they appear on the LHS of any
statement in WS_ENTRY_BB. If so, then we cannot emit the combined
call.
hack something up here, it is really not worth the aggravation. */
