profiled bootstrap

[kevin diggs]

Hi,

Does an installed compiler have (did it store somehow) an indication
that it was built using profile feedback?

Also, can I build an Ada (and C) in a non-profiled version and install
them into, say:

/opt/gcc-4.3.5-profiled

and then build everything else (including an explicit C) as profiled
and install them into the same place and have it ... do what I
expect/hope (i.e. C is replaced with a profiled version without
screwing up the non-profiled Ada)?

Does profiling affect all parts or C only?

Thanks!
