* Fix bug with critical edge splitting code where it wouldn't update PHI nodesChris Lattner2002-09-061-2/+12
| | | | | | | in the old destination block to indicate that the value flows from the new edge splitting block, not from the original multi-successor block. llvm-svn: 3590

* - Cleaned up the interface to AnalysisUsage to take analysis class namesChris Lattner2002-08-081-1/+1

* Cleanup ConstantExpr handling:Chris Lattner2002-07-301-8/+2
| | | | | | | | | | | | | | * Correctly delete TypeHandles in AsmParser. In addition to not leaking memory, this prevents a bug that could have occurred when a type got resolved that the constexpr was using * Check for errors in the AsmParser instead of hitting assertion failures deep in the code * Simplify the interface to the ConstantExpr class, removing unneccesary parameters to the ::get* methods. * Rename the 'getelementptr' version of ConstantExpr::get to ConstantExpr::getGetElementPtr llvm-svn: 3160
