* fix some serious miscompiles on ia64, alpha, and ppcChris Lattner2005-04-131-1/+1
* avoid work when possible, perhaps fix the problem nate and andrew are seeingChris Lattner2005-04-131-0/+1
* Implement expansion of unsigned i64 -> FP.Chris Lattner2005-04-131-2/+31
* Make expansion of uint->fp cast assert out instead of infinitely recurse.Chris Lattner2005-04-131-1/+1

* Remove some redundant checks, add a couple of new ones. This allows us toChris Lattner2005-04-121-7/+5
* Emit comparisons against the sign bit better. Codegen this:Chris Lattner2005-04-121-0/+10
* Emit long comparison against -1 better. Instead of this (x86):Chris Lattner2005-04-121-0/+10
