2005-04-19Wrap some long lines.Chris Lattner
Make IPSCCP strip off dead constant exprs that are using functions, making them appear as though their address is taken. This allows us to propagate some more pool descriptors, lowering the overhead of pool alloc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21363 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-19Major change to tblgen: instead of resolving values every time a class isChris Lattner
finished up, only resolve fully when the def is defined. This allows things to be changed and all uses to be propagated through. This implements TableGen/LazyChange.td and fixes TemplateArgRename.td in the process. None of the .td files used in LLVM backends are changed at all by this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21344 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-15a new simple pass, which will be extended to be more useful in the future.Chris Lattner
This pass forward branches through conditions when it can show that the conditions is either always true or false for a predecessor.
