[Openmp-dev] Using opt tool

[Abid Malik via Openmp-dev]

Hello,

I am compiling an OpenMP program using clang

clang -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk
-O3 -fopenmp -emit-llvm -S -c  test1.c -o test1.ll

However when I try to compiler test1.ll using opt
$ opt -S -O3 test1.ll

Stack dump:
0. Program arguments: opt -S -O3 test1.ll
1. Running pass 'CallGraph Pass Manager' on module 'test1.ll'.
