cross compilation

[Shyam Saini]

Hi all,

I'm trying to figure out optimized code for some network drivers. I'm
replacing certain APIs in the code and compare code for each API.

To choose best optimized code, i need to first compile them and then
disassemble  the compiled code, where a change in single line would make a
significant difference in
the performance.

So, my question is how to compile* x86 based network drivers  on x86_64
Ubuntu machine*. Currently I'm running Ubuntu 14.04.

Please help me out


Thanks
