Package-level declarations

Types

class DeclarationHandler(lang: LLVMIRLanguageFrontend) : Handler<Declaration, Pointer, LLVMIRLanguageFrontend>

This handler is in charge of parsing all LLVM IR language constructs that are related to declarations, mainly functions and types.

ExpressionHandler

class ExpressionHandler(lang: LLVMIRLanguageFrontend) : Handler<Expression, LLVMValueRef, LLVMIRLanguageFrontend>

This handler primarily handles operands, as returned by LLVMGetOperand and turns them into an Expression. Operands are basically arguments to an instruction.

LLVMIRLanguage

class LLVMIRLanguage : Language<LLVMIRLanguageFrontend>

The LLVM IR language.

LLVMIRLanguageFrontend

class LLVMIRLanguageFrontend(language: Language<LLVMIRLanguageFrontend>, ctx: TranslationContext) : LanguageFrontend<Pointer, LLVMTypeRef>

Because we are using the C LLVM API, there are two possibly AST nodes that we need to consider: LLVMValueRef and LLVMBasicBlockRef. Because they do not share any class hierarchy, we need to resort to use Pointer as the AST node type here.

StatementHandler

class StatementHandler(lang: LLVMIRLanguageFrontend) : Handler<Statement, Pointer, LLVMIRLanguageFrontend>

Properties

name

val LLVMValueRef.name: String

Returns the name of a value using LLVMGetValueName.

opCode

val LLVMValueRef.opCode: Int

Returns the opcode for an instruction using LLVMGetInstructionOpcode.

symbolName

val LLVMValueRef.symbolName: String

Returns the name / identified of a value, if it is a variable, including the "scope" symbol, i.e., % for local and @ for global variables.
