Hi.
This is a first part fixing the PR. It makes sense making "naked" functions
"noipa".
What's missing is IPA MOD pass support where the pass should not optimize fns
with "noipa" attributes.
@Honza: Can you please implement that?
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
