[LLVMdev] Usage of llvmc (Sorry. Please disregard the right above.)

[Seung Jae Lee]

Thank you so much for your reply, Chris. 
If so, can I ask you two things more? 

First, is there any way to have various optimizations on LLVM assembly such as -O options in llvmc? 
llvm-gcc doesn't seem to be working for these -O options... 

Second, I'm still not sure about difference between *.s and *.ll. 
LLVM assembly *.s file can be made from llvm-gcc with -S option. 
Another assembly *.ll file comes from just llvm-gcc and llvm-dis. 
Is the difference between these two extensions on the optimized state? 

Thanks, 
Seung J. Lee
