[LLVMdev] Optimization application by llvm-gcc, opt

[Raghu Prabhakar]

Hi all,

I wanted to clarify something about the application of optimizations by llvm-gcc, opt and llc.

Will the following two sequences generate the same optimized bitcode?
   a) $ llvm-gcc -O3 -c -emit-llvm foo.c  -o foo.bc
   b) $ llvm-gcc -O0 -c -emit-llvm foo.c -o foo.bc
      $ opt -O3 foo.bc
