3201 | ||
3202 | If CTX is a nested parallel directive, we may have to use the decl | |
3203 | mappings created in CTX's parent context. Suppose that we have the | |
3204 | following parallel nesting (variable UIDs showed for clarity): | |
3205 | ||
3206 | iD.1562 = 0; | |
3207 | #omp parallel shared(iD.1562) -> outer parallel | |
3208 | iD.1562 = iD.1562 + 1; | |
3209 | ||
3210 | #omp parallel shared (iD.1562) -> inner parallel | |
3211 | iD.1562 = iD.1562 - 1; | |
3212 | ||
3213 | Each parallel structure will create a distinct .omp_data_s structure | |
3214 | for copying iD.1562 in/out of the directive: | |
3215 | ||
3216 | outer parallel .omp_data_s.1.i -> iD.1562 | |
3217 | inner parallel .omp_data_s.2.i -> iD.1562 | |
3218 | ||
3219 | A shared variable mapping will produce a copy-out operation before | |
3220 | the parallel directive and a copy-in operation after it. So, in | |
3221 | this case we would have: | |
3222 | ||
3223 | iD.1562 = 0; | |
3224 | .omp_data_o.1.i = iD.1562; | |
3225 | #omp parallel shared(iD.1562) -> outer parallel | |
3226 | .omp_data_i.1 = &.omp_data_o.1 | |
3227 | .omp_data_i.1->i = .omp_data_i.1->i + 1; | |
3228 | ||
3229 | .omp_data_o.2.i = iD.1562; -> ** | |
3230 | #omp parallel shared(iD.1562) -> inner parallel | |
3231 | .omp_data_i.2 = &.omp_data_o.2 | |
3232 | .omp_data_i.2->i = .omp_data_i.2->i - 1; | |
3233 | ||
3234 | ||
3235 | ** This is a problem. The symbol iD.1562 cannot be referenced | |
3236 | inside the body of the outer parallel region. But since we are | |
3237 | emitting this copy operation while expanding the inner parallel | |
3238 | directive, we need to access the CTX structure of the outer | |
3239 | parallel directive to get the correct mapping: | |
3240 | ||
3241 | .omp_data_o.2.i = .omp_data_i.1->i | |
3242 | ||
3243 | Since there may be other workshare or parallel directives enclosing | |
3244 | the parallel directive, it may be necessary to walk up the context | |
3245 | parent chain. This is not a problem in general because nested | |
3246 | parallelism happens only rarely. */ | |
