Functions

open override fun codeOf(astNode: Pointer): String?

open fun handle(ctx: Pointer): Statement?

handleBinaryOperator

fun handleBinaryOperator(instr: LLVMValueRef, op: String, unsigned: Boolean, unordered: Boolean = false): Expression

Handles a binary operation and returns either a BinaryOperator, UnaryOperator, CallExpression or a DeclarationStatement.

handleIntegerComparison

fun handleIntegerComparison(instr: LLVMValueRef): Expression

Handles the icmp instruction for comparing integer values.

fun handlePhi(instr: LLVMValueRef, tu: TranslationUnitDeclaration, flatAST: MutableList<Node>)

Handles the phi instruction. It therefore adds dummy statements to the end of basic blocks where a certain variable is declared and initialized. The original phi instruction is not added to the CPG.

open override fun locationOf(astNode: Pointer): PhysicalLocation?
