Bug #: 52137 Summary: bdver2 scheduler needs to be added to bdver1 insn reservations Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: blocker Priority: P3 Component: target AssignedTo: unassig...@gcc.gnu.org ReportedBy: qne...@gcc.gnu.org Created attachment 26585 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26585 Add bdver2 to list of cpu attributes for bdver1.md insn reservations The bdver2 scheduler lacks insn reservation conditions for cpu attributes in the bdver1.md model. The resulting generated code regresses on bdver2 hardware for SPEC and polyhedron. The attached patch recovers most of this performance regression.
