* Next round of APFloat changes.Dale Johannesen2007-09-062-4/+6
| | | | | | | | | | | | | | | Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces. Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8

* VStudio compiler errors and placing Function*->ExFunc map under ↵Chuck Rose III2007-07-271-4/+5
| | | | | | | | | | | | | ManagedStatic control. This commit fixes two things. One is a pair of VStudio compiler errors stemming from variables which defined within the for loop statement and also within the body of the for loop. I fixed these by renaming one of the two variables. Additionally, I've made the Function*->ExFunc map in ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown. In repeated uses of the interpreter, where the same Function* address may get used for completely differnet functions, this was causing a crash. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40558 91177308-0d34-0410-b5e6-96231b3b80d8
