I would like to get to a point where: 1- The IL saved by the front end is independent from all (or most) compiler flags. 2- The final link is the one that determines what flags are used to generate final code This way, one could generate completely independent byte-code files that can be shipped and re-compiled with any flags. This doesn't address the problem of what happens if a single file needs special code generation flags. For those cases, one could generate final code from the byte-code file separately and link it to the final executable: $ gcc -c <special-flags> special-file.o $ gcc -flto special-file.o <other-files> -o prog This would probably not cover all the use cases, but right now we don't even have (1). Diego.
