You are better off run passes explicitly using opt. Try this:
llvm-gcc -c -o - -O1 my_proc.c -emit-llvm -mllvm --disable-llvm-optzns | opt list_of_passes
Passing -O1 to llvm-gcc means that gcc will perform constant folding and
some other small optimizations. Passing -emit-llvm means that LLVM bitcode
is produced, suitable for piping to opt. -mllvm --disable-llvm-optzns means
that the LLVM optimizers will not be run.

[LLVMdev] O3 passes
Can I specify passes that I want run directly to llvm-gcc? I don't want
all of -O3, for example. I tried llvm-gcc -raiseallocs ..., but that
didn't work. I also tried running cc1 directly and it didn't take
-raiseallocs as a parameter either.
