* - Make Value::replaceAllUsesWith work with constants correctly. This fixesChris Lattner2002-10-091-16/+18
| | | | | | | bug FuncResolve/2002-08-19-ResolveGlobalVars.ll and gzip looks better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4103 91177308-0d34-0410-b5e6-96231b3b80d8

* Almost a complete rewrite of FunctionResolution to now resolve functionsChris Lattner2002-10-091-122/+213
| | | | | | | | | | | | | | | and global variables. This fixes bug: FuncResolve/2002-08-19-ResolveGlobalVarsEasier.ll And bug: SingleSource/UnitTests/2002-10-09-ArrayResolution.c Note that this does not fix bug: FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith breaks when a constantexpr is pointing to the thing being replaced. This is more of an infrastructure problem than anything. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4099 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | powerful, but that are largely disabled. The basic idea here is that it is trying to forward branches across basic blocks that have PHI nodes in it, which are crucial to be able to handle cases like whet.ll. Unfortunately we are not updating SSA correctly, causing sim.c to die, and I don't have time to fix the regression now, so I must disable the functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4077 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a nasty problem with dominance calculation for unreachable blocks.Chris Lattner2002-10-041-5/+20
| | | | | | | | | | If we had a CFG that look like Entry -> B, Unreachable -> B, then we would not correctly determine that Entry dominated B, because Entry did not apparently dominate "unreachable". This patch fixes this by making the entry node dominate all blocks, including unreachable ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4037 91177308-0d34-0410-b5e6-96231b3b80d8
