[LLVMdev] Adding option to LLVM opt to disable a specific pass from command line

[Seb]

Hi all,

I would like to add an option for LLVM 'opt' to disable a specific
optimization pass from command line.

The idea is to have something like:

opt -O2 -disable-pass=[passname,...]

Do you think it could be useful ? How should I proceed to develop it and
commit changes to LLVM trunk ?
Thanks for your advices and recommandations.
Best Regards
Seb
