------- Comment #15 from jakub at gcc dot gnu dot org 2010-01-19 09:03 -------
This patch seems to fix issues with (most of) KDE testcases, but there are
still some testcases where gcc spends very long time in var-tracking (usually
generated huge routines where simply too many VALUEs are tracked through).
E.g. https://bugzilla.redhat.com/show_bug.cgi?id=548826 and
https://bugzilla.redhat.com/show_bug.cgi?id=531218
These can be worked around by the #c9 patch, even with much bigger default
(50mil).
Not sure if we should track this all in this bug, or just split into separate
bugs.
