Hi all, I'm trying to compile an application for two different target architectures using gcc. My goal is to obtain 2 output binaries that have the same control flow graph structure. The problem is that , some architecture-dependent optimizations tend to modify the cfg structure by removing/merging basic blocks etc. Trying to disable such optimizations (using command line options), I found that this was rather a complex task cause they are dispersed across different optimization passes, and some times mixed with other types of optimizations. So my question is : Is there a simple and clean why to disable/enable architecture-dependent optimizations that affect the cfg structure in gcc? Thanks in advance for any hint or comment Aimen
