Detailed Description

Abstraction over function prototypes. Contains helpers to build prototypes and generate IR for the types.

Function * impala::LlvmCodeGen::FnPrototype::GeneratePrototype	(	LlvmBuilder *	builder = NULL,
		llvm::Value **	params = NULL
	)

Generate LLVM function prototype. If a non-null builder is passed, this function will also create the entry block and set the builder's insert point to there. If params is non-null, this function will also return the arguments values (params[0] is the first arg, etc). In that case, params should be preallocated to be number of arguments
