[LLVMdev] Executing a transformed program

[Alysson]

Thank you for the answer Reid.
I've been already using the format `opt -load MyPass.so -my-pass input.bc -o
output.bc`.
But my problem is to execute the .s generated file.
As long as I know, gcc compiler is capable to generate target machine code
from assembly.
So I tried to compile it with gcc to generate machine code, but there was
many problems.
Is there any way to compile and run .s files?

Best regards,
Alysson
