Hi all,

I would like to know what are the options to use with 3.3rc1 llc/opt to 32-bit (NOT 64-bit) code on a Sandy Bridge processor ?
I've defined a datalayout that use a 32-bit as pointer size and I'm passing -march=x86 to llc, is it enough ?
I'm not using CLANG as front-end.

Thanks for your answer
