From 05be1da24cd947187a8b750e9eca45e80d2e7414 Mon Sep 17 00:00:00 2001 From: Alexey Bataev Date: Thu, 18 Jul 2019 17:49:13 +0000 Subject: [OPENMP]Provide correct data sharing attributes for loop control variables. Loop control variables are private in loop-based constructs and we shall take this into account when generate the code for inner constructs. Currently, those variables are reported as shared in many cases. Moved the analysis of the data-sharing attributes of the loop control variable to an early semantic stage to correctly handle their attributes. llvm-svn: 366474 --- clang/test/OpenMP/task_codegen.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'clang/test/OpenMP/task_codegen.c') diff --git a/clang/test/OpenMP/task_codegen.c b/clang/test/OpenMP/task_codegen.c index 6669c7e7361..69718cc6f4d 100644 --- a/clang/test/OpenMP/task_codegen.c +++ b/clang/test/OpenMP/task_codegen.c @@ -32,4 +32,19 @@ int main() { // CHECK: call i8* @__kmpc_omp_task_alloc( // CHECK: call i32 @__kmpc_omp_task( // CHECK: call void @__kmpc_end_taskgroup( + +// CHECK-LINE: @bar +void bar() { + // CHECK: call void @__kmpc_for_static_init_4( +#pragma omp for +for (int i = 0; i < 10; ++i) + // CHECK: [[BUF:%.+]] = call i8* @__kmpc_omp_task_alloc(%struct.ident_t* @{{.+}}, i32 %{{.+}}, i32 1, i64 48, + // CHECK: [[BC_BUF:%.+]] = bitcast i8* [[BUF]] to [[TT_WITH_PRIVS:%.+]]* + // CHECK: [[PRIVS:%.+]] = getelementptr inbounds [[TT_WITH_PRIVS]], [[TT_WITH_PRIVS]]* [[BC_BUF]], i32 0, i32 1 + // CHECK: [[I_PRIV:%.+]] = getelementptr inbounds %{{.+}}, %{{.+}} [[PRIVS]], i32 0, i32 0 + // CHECK: store i32 %{{.+}}, i32* [[I_PRIV]], + // CHECK: = call i32 @__kmpc_omp_task(%struct.ident_t* @{{.+}}, i32 %{{.+}}, i8* [[BUF]]) +#pragma omp task +++i; +} #endif -- cgit v1.2.3
