Chris Lattner 2f690c84fa Implement a few symbolic constant folding things. X ? Y : Y is Y. ... Fold: seteq ({ short }* cast (int 1 to { short }*), { short }* null) setlt ({ short }* cast (int 1 to { short }*), { short }* cast (int 2 to { short }*)) to false/true. These last two commonly occur in the output of compilers that tag integers, like cozmic's scheme compiler. Tested by Regression/Assembler/ConstantExprFold.llx git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25112 91177308-0d34-0410-b5e6-96231b3b80d8		2006-01-05 07:49:30 +00:00
