[Bug bootstrap/37426] New: [4.4 regression] IRA merge breaks Tru64 UNIX bootstrap

[ro at gcc dot gnu dot org]

As of 20080903, mainline doesn't bootstrap on alpha-dec-osf5.1b: in stage2,
compiling build/gengtype-lex.o results in an ICE:

This might be identical to PR rtl-optimization/37333.  I'm currently running
a mainline bootstrap as of 20080908 to check.

------- Comment #1 from ro at techfak dot uni-bielefeld dot de  2008-09-09 15:43 -------
Subject: Re:  [4.4 regression] IRA merge breaks Tru64 UNIX bootstrap

After applying the patch for PR rtl-optimization/37333 from

        http://gcc.gnu.org/ml/gcc-patches/2008-09/msg00514.html

and applying

        http://gcc.gnu.org/ml/gcc-patches/2008-09/msg00705.html

I'm now past stage3 and into building the target libs.  So it seems that
this PR can be closed once the patch is checked in.

------- Comment #2 from ro at gcc dot gnu dot org  2008-09-29 15:14 -------
Both patches have been checked in, so closing as fixed.
(We're back at PR bootstrap/36851 now, though.)
