I'll post this patch series (the current state of my fkeep-vars-live
branch) in reply to this email:
1 [debug] Add fdebug-nops
2 [debug] Add fkeep-vars-live
3 [debug] Add fdebug-nops and fkeep-vars-live to Og only
Bootstrapped and reg-tested on x86_64. ChangeLog entries and function
header comments missing.
Comments welcome.
Thanks,
