[Openmp-dev] OpenMP LIT tests for OpenMPOpt pass

[Abid Malik via Openmp-dev]

Hello,

I am writing test cases for the OpenMPOpt pass. I am dumping the IR and
then checking the correctness of IR (after certain openmp related
optimizations). For example;
// RUN: %clang_cc1 -verify -fopenmp -O3 -x c -std=c99 -emit-llvm %s -o - |
FileCheck %s
// expected-no-diagnostics

void test_1(){

#pragma omp parallel
{
#pragma omp for
for (int i=0; i < 100; i++);
}
}

// CHECK: define void @test_1()
// CHECK: ...) @__kmpc_for_call(
// CHECK: ret void
// CHECK: define internal void @.omp_outlined.(
// CHECK: call void @__kmpc_for_static_init_4(
// CHECK: call void @__kmpc_for_static_fini(
// CHECK-NEXT: call void @__kmpc_barrier(
// CHECK: ret void


Is this a valid test format for the pass or should it be through the opt
tool?
