Detailed Description

Functions in this group model LLVMValueRef instances that correspond to constants referring to scalar types.

For integer types, the LLVMTypeRef parameter should correspond to a llvm::IntegerType instance and the returned LLVMValueRef will correspond to a llvm::ConstantInt.

For floating point types, the LLVMTypeRef returned corresponds to a llvm::ConstantFP.
