--- Additional Comments From rth at gcc dot gnu dot org 2005-01-19 21:21 --- Yes, it's certainly possible. But indeed pr19511 shows that you can't even get that far with --with-arch=pentium3 at the moment, due to changes that post-date this report. After I get a fix for that problem, will you please re-test? Hopefully I'll have magically fixed this problem which was never sufficiently isolated... -- What|Removed |Added BugsThisDependsOn||19511 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19174
