------- Comment #8 from jamborm at gcc dot gnu dot org 2009-07-28 21:33 -------
I can confirm that if we schedule pass_ccp right after pass_sra_early,
g gets inlined. Moreover, if we schedule one more pass_forwprop right
afterwards, even the testcase for PR 3713, comment #12 gets optimized
as it should :-)
So, like with PR 3713, we either have to schedule ccp or add some
specific pattern matching to the inlining preparation phase. I guess
that people will find running one more ccp and fwprop unacceptable and
so some pattern matching will have to be done anyway for the other PR
(and we already do some awkward stuff like that for indirect member
pointer calls). Perhaps we can match both, this one would be very
easy. (Or is scheduling the two extra passes an option?)
