Expr
Abstract class in which all expressions in Brain implement from.
Definition: Expr.h:62
IfExpr::ast_code_gen
void ast_code_gen()
Method for the reverse code generation from the AST. It prints out to the stdout the token itself...
Definition: IfExpr.cpp:124
IfExpr::debug_description
void debug_description(int level)
Prints debug information when Brain&#39;s compiler has the active flags: -v | -emit-ast.
Definition: IfExpr.cpp:78
IfExpr::expression_category
ExpressionType expression_category()
Returns the category of the expression given by the caller.
Definition: IfExpr.cpp:148
IfExpr::code_gen
void code_gen(llvm::Module *M, llvm::IRBuilder<> &B, llvm::BasicBlock *BreakBB)
Generates the IR (Intermediate Representation) code to be executed by llvm.
Definition: IfExpr.cpp:11
