Re: Question about default optimizations


Hi Sebastian, 

Yes I already checked that using gcc -Q -O* --help=optimizers.

I found that default optimizations (I mean options are not controlled
through CLI) :

#O2 = #O3, #O1 <#O2, #Os > #O2

I read also that researchers in iterative compilation community, made
assumptions to choose one of the standard optimization levels to apply over
their generated sequences.

I would like to confirm this findings with GCC hackers here :)
