[llvm-dev] Experimenting with opt -Os/-Oz

[Fernando Magno Quintao Pereira via llvm-dev]

Dear LLVMers,

     I would like to fiddle a bit with two standard optimization
levels (Os/Oz) used by opt. So, could someone tell me where, in the
implementation of LLVM, is the order of the passes within those levels
defined? Ideally, I would like to recompile LLVM and change the
default levels in my experiments.

Kind regards,

Fernando
