Chris Lattner 94de563118 Substantially improve code generation for address exposed locals (aka fixed ... sized allocas in the entry block). Instead of generating code like this: entry: reg1024 = ESP+1234 ... (much later) *reg1024 = 17 Generate code that looks like this: entry: (no code generated) ... (much later) t = ESP+1234 *t = 17 The advantage being that we DRAMATICALLY reduce the register pressure for these silly temporaries (they were all being spilled to the stack, resulting in very silly code). This is actually a manual implementation of rematerialization :) I have a patch to fold the alloca address computation into loads & stores, which will make this much better still, but just getting this right took way too much time and I'm sleepy. llvm-svn: 13554		2004-05-13 07:40:27 +00:00
