I don't know if this is a regression or not. But I decided to test my latest data-ref patch more than I tested my old one via testing bootstrap with the vectorizer turned on, I noticed the dfp tests would fail. The assembly for the tests were the same, the problem is we were creating wrong code for one of the support functions in libgcc, I have not had time to check which one. I thought I would file this bug before forgetting about this issue.
Again BOOT_CFLAGS was set to "-O2 -g -msse2 -ftree-vectorize". When I have more time I will look into it. -- Summary: BOOT_CFLAGS="-O2 -g -msse2 -ftree-vectorize" causes dfp tests to fail Product: gcc Version: 4.3.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: pinskia at gcc dot gnu dot org GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32093
