OpenMP: Support complex/float in && and || reduction C/C++ permit logical AND and logical OR also with floating-point or complex arguments by doing an unequal zero comparison; the result is an 'int' with value one or zero. Hence, those are also permitted as reduction variable, even though it is not the most sensible thing to do. gcc/c/ChangeLog: * c-typeck.c (c_finish_omp_clauses): Accept float + complex for || and && reductions. gcc/cp/ChangeLog: * semantics.c (finish_omp_reduction_clause): Accept float + complex for || and && reductions. gcc/ChangeLog: * omp-low.c (lower_rec_input_clauses, lower_reduction_clauses): Handle && and || with floating-point and complex arguments. libgomp/ChangeLog: * testsuite/libgomp.c-c++-common/reduction-1.c: New test. * testsuite/libgomp.c-c++-common/reduction-2.c: New test. * testsuite/libgomp.c-c++-common/reduction-3.c: New test. gcc/c/c-typeck.c | 10 +- gcc/cp/semantics.c | 8 +- gcc/omp-low.c | 76 +++++++- .../testsuite/libgomp.c-c++-common/reduction-1.c | 192 +++++++++++++++++++++ .../testsuite/libgomp.c-c++-common/reduction-2.c | 192 +++++++++++++++++++++ .../testsuite/libgomp.c-c++-common/reduction-3.c | 192 +++++++++++++++++++++ 6 files changed, 651 insertions(+), 19 deletions(-) diff --git a/gcc/c/c-typeck.c b/gcc/c/c-typeck.c index 3b45cfda0ff..fdc7bb6125c 100644 --- a/gcc/c/c-typeck.c +++ b/gcc/c/c-typeck.c @@ -14097,6 +14097,8 @@ c_finish_omp_clauses (tree clauses, enum c_omp_region_type ort) case PLUS_EXPR: case MULT_EXPR: case MINUS_EXPR: + case TRUTH_ANDIF_EXPR: + case TRUTH_ORIF_EXPR: break;
