2007-07-27VStudio compiler errors and placing Function*->ExFunc map under ↵Chuck Rose III
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

2007-01-19For PR1043:Reid Spencer
This is the final patch for this PR. It implements some minor cleanup in the use of IntegerType, to wit: 1. Type::getIntegerTypeMask -> IntegerType::getBitMask 2. Type::Int*Ty changed to IntegerType* from Type* 3. ConstantInt::getType() returns IntegerType* now, not Type* This also fixes PR1120.
