* Restructure call constant folding code a bit to make it simplerChris Lattner2004-05-27
| | | | | | | | | Add support for acos/asin/atan. 188.ammp contains three calls to acos with constant arguments. Constant folding it allows elimination of those 3 calls and three FP divisions of the results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13821 91177308-0d34-0410-b5e6-96231b3b80d8
