ast_to_llvm()

LLVMValue ast_to_llvm	(	ASTNode *	root,
		LLVMValue	llvm_value,
		TokenType	parent_operation
	)

Generates LLVM-IR from a given AST.

Parameters

n	The AST Node from which LLVM will be generated
llvm_value	LLVMValue storing register or label information
parent_operation	TokenType of parent of n

Returns

LLVMValue LLVMValue struct containing information about what code this AST Node generated

determine_binary_expression_stack_allocation()

Parameters

root	Root of AST to find stack allocation for

Returns

LLVMStackEntryNode* Pointer to front of the stack allocation linked list

generate_llvm()

void generate_llvm

(

void

)
