Giuliano,
I asked for some documentation off you related to the RTL passes. Not sure
if you are just hitting bottlenecks in all_rtl_passes or ipa_passes functions
but it seems that the SSA trees and cfgloop.c and cfgloop.h files optimization
passes would still be a issue. Particularly after the final GIMPLE and IPA
passes it would be great to multi-thread and be able to walk the dominator
trees multi-threaded.
Not sure if you've looked as what seem to be issues here and was wondering
if these are happening in your profiling still. GENERIC to GIMPLE may also
be a issue in gimipfly but less than those.
Again I understand if's out of scope but it would be great if you have a current
profile graph that I can see. It would give me an idea of where to start working
outside of the core GIMPLE optimizations passes your working on.
Huge thanks and again good luck,
Nick
P.S. Don't worry if you don't it would just be nice to have and rewriting multi-threaded
memory allocation is not easy and even more so with the shared state between compiler
passes.
