i686-apple-darwin9 bootstrap is broken since r162678 (with an ICE reported for other targets as well). Since this was fixed (at r162697), it has unmasked another fail which is still present at 162778.
unfortunately, the other bootstrap bug prevents narrowing this down more... however; This is a compare-debug fail of cfgexpand.o. Looking at the .s files (to be attached) there seem to be instruction ordering differences. this bug is _not_ present in powerpc-apple-darwin9 or x86_64-apple-darwin10. -- Summary: [4.6 Regression] bootstrap debug-compare fail Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: blocker Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: iains at gcc dot gnu dot org GCC target triplet: i686-apple-darwin9 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45150
