[cfe-dev] clang vs llc

[Luc Bourhis]

Hi,

I think I understand reasonably well what the following does:

~> clang foo.c -emit-llvm -c -o foo.bc
~> llc foo.bc -O3 -o foo.o

However, I am not quite sure about the straightforward

~> clang foo.c -c -o foo.o

Is the latter doing just the same as the former but all in memory? If not, what are the differences?
