Yep, there is quite some potential in this on x86. On x86-64 also stack alignment prologues could be eliminated. I guess the PIC tricks could do wonders for Mozilla. Additionally once this works, we can move ahead with alternate entry points at gimple level possibly re-implementing thunks/ctor clonning using them. So if we finally get past the unwind info issues, I could start poking about getting the PIC codegen working as a first experiment.
