| 132 | directive at PAR_ENTRY_BB as a combined parallel+workshare region. |
| 133 | |
| 134 | When expanding a combined parallel+workshare region, the call to |
| 135 | the child function may need additional arguments in the case of |
| 136 | GIMPLE_OMP_FOR regions. In some cases, these arguments are |
| 137 | computed out of variables passed in from the parent to the child |
| 138 | via 'struct .omp_data_s'. For instance: |
| 139 | |
| 140 | #pragma omp parallel for schedule (guided, i * 4) |
| 141 | for (j ...) |
| 142 | |
| 143 | Is lowered into: |
| 144 | |
| 145 | # BLOCK 2 (PAR_ENTRY_BB) |
| 146 | .omp_data_o.i = i; |
| 147 | #pragma omp parallel [child fn: bar.omp_fn.0 ( ..., D.1598) |
| 148 | |
| 149 | # BLOCK 3 (WS_ENTRY_BB) |
| 150 | .omp_data_i = &.omp_data_o; |
| 151 | D.1667 = .omp_data_i->i; |
| 152 | D.1598 = D.1667 * 4; |
| 153 | #pragma omp for schedule (guided, D.1598) |
| 154 | |
| 155 | When we outline the parallel region, the call to the child function |
| 156 | 'bar.omp_fn.0' will need the value D.1598 in its argument list, but |
| 157 | that value is computed *after* the call site. So, in principle we |
| 158 | cannot do the transformation. |
| 159 | |
| 160 | To see whether the code in WS_ENTRY_BB blocks the combined |
| 161 | parallel+workshare call, we collect all the variables used in the |
| 162 | GIMPLE_OMP_FOR header check whether they appear on the LHS of any |
| 163 | statement in WS_ENTRY_BB. If so, then we cannot emit the combined |
| 164 | call. |
| 165 | |
| 166 | FIXME. If we had the SSA form built at this point, we could merely |
| 167 | hoist the code in block 3 into block 2 and be done with it. But at |
| 168 | this point we don't have dataflow information and though we could |
| 169 | hack something up here, it is really not worth the aggravation. */ |
