2004-07-27This is the regression test for the change to InstructionCombining.cppRobert Bocchino
that I made today. It illustrates that the old version of the code would crash if the RHS of a multiplication were a ConstantExpr that could not be resolved into a ConstantInt or ConstantFP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15292 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-27This change fixed a bug in the function visitMul. The prior versionRobert Bocchino
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15291 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-27As it happens, none of these TargetInstrInfo methods which are onlyBrian Gaeke
