[Openmp-dev] OpenMP for loop

At LLVM IR level - no, only in the AST.

Thanks. Is there a way to get the actual loop increment. I am comparing two loops wrt the increment value. It seems I always get the same "1" value no matter how I define the loop increment.

Hello,

When compiling the following loop with clang:


void before (int N){
        #pragma omp for nowait
        for (int i=0; i < N; i=i+3)
                g(i);
}



I get :


call void @__kmpc_for_static_init_4(%struct.ident_t* @0, i32 %13, i32 34, i32* %11, i32*
%8, i32* %9, i32* %10, i32 1, i32 1)


As per definition the second last argument  gives loop increment. Now for the given loop, should it be 3? Why am I getting "1"?


Thanks,
