* This change fixed a bug in the function visitMul. The prior versionRobert Bocchino2004-07-271-3/+3
| | | | | | | | | | | | | | | assumed that a constant on the RHS of a multiplication was either an IntConstant or an FPConstant. It checked for an IntConstant and then, if it did not find one, did a hard cast to an FPConstant. That code would crash if the RHS were a ConstantExpr that was neither an IntConstant nor an FPConstant. This version replaces the hard cast with a dyn_cast. It performs the same way for IntConstants and FPConstants but does nothing, instead of crashing, for constant expressions. The regression test for this change is 2004-07-27-ConstantExprMul.ll. llvm-svn: 15291

| | | | | | | | | used in the SparcV9 backend really have anything to do with TargetInstrInfo, so we're converting them into regular old global functions and moving their declarations to SparcV9InstrSelectionSupport.h. (They're mostly used as helper functions for SparcV9InstrSelection.) llvm-svn: 15277

* Save and restore LR just like any other register and ONLY if we actually modifyMisha Brukman2004-07-271-11/+20
