Inherited predicates
getAPredecessor | Gets all direct predecessors of this instruction. | from Instruction |
getASuccessor | Gets all direct successors of this instruction. | from Instruction |
getAUse | Gets all direct uses of the result of this instruction. The result can be an | from Instruction |
getAnOperand | Gets all of this instruction’s operands. | from Instruction |
getAst | Gets the AST that caused this instruction to be generated. | from Instruction |
getBackEdgeSuccessor | Gets the a back-edge successor of this instruction along the control flow edge specified by | from Instruction |
getBlock | Gets the basic block that contains this instruction. | from Instruction |
getConvertedResultExpression | Gets the | from Instruction |
getDisplayIndexInBlock | Gets the zero-based index of this instruction within its block. This is used by debugging and printing code only. | from Instruction |
getDumpString | Gets a string showing the result, opcode, and operands of the instruction, equivalent to what would be printed by PrintIR.ql. For example: | from Instruction |
getElementSize | Gets the size of the elements pointed to by the pointer operands, in bytes. | from PointerArithmeticInstruction |
getEnclosingFunction | Gets the function that contains this instruction. | from Instruction |
getEnclosingIRFunction | Gets the IRFunction object that contains the IR for this instruction. | from Instruction |
getImmediateString | Gets a string describing the immediate value of this instruction, if any. | from PointerArithmeticInstruction |
getLeft | Gets the instruction whose result provides the value of the left operand of this binary instruction. | from BinaryInstruction |
getLeftOperand | Gets the left operand of this binary instruction. | from BinaryInstruction |
getLocation | Gets the location of the source code for this instruction. | from Instruction |
getOpcode | Gets the opcode that specifies the operation performed by this instruction. | from Instruction |
getOperandsString | Gets a string describing the operands of this instruction, suitable for display in IR dumps. | from Instruction |
getOperationString | Gets a string describing the operation of this instruction. This includes the opcode and the immediate value, if any. For example: | from Instruction |
getPredecessor | Gets a predecessor of this instruction such that the predecessor reaches this instruction along the control flow edge specified by | from Instruction |
getResultAddress | Gets the instruction that holds the exact memory address to which this instruction stores its result, if any. For example, in | from Instruction |
getResultAddressOperand | Gets the operand that holds the memory address to which this instruction stores its result, if any. For example, in | from Instruction |
getResultIRType | Gets the type of the result produced by this instruction. If the instruction does not produce a result, its result type will be | from Instruction |
getResultId | Gets a human-readable string that uniquely identifies this instruction within the function. This string is used to refer to this instruction when printing IR dumps. | from Instruction |
getResultLanguageType | Gets the language-specific type of the result produced by this instruction. | from Instruction |
getResultMemoryAccess | Gets the kind of memory access performed by this instruction’s result. Holds only for instructions with a memory result. | from Instruction |
getResultSize | Gets the size of the result produced by this instruction, in bytes. If the result does not have a known constant size, this predicate does not hold. | from Instruction |
getResultString | Gets a string describing the result of this instruction, suitable for display in IR dumps. This consists of the result ID plus the type of the result. | from Instruction |
getResultType | Gets the type of the result produced by this instruction. If the instruction does not produce a result, its result type will be | from Instruction |
getRight | Gets the instruction whose result provides the value of the right operand of this binary instruction. | from BinaryInstruction |
getRightOperand | Gets the right operand of this binary instruction. | from BinaryInstruction |
getSuccessor | Gets the successor of this instruction along the control flow edge specified by | from Instruction |
getUnconvertedResultExpression | Gets the unconverted form of the | from Instruction |
getUniqueId | Gets a string identifier for this function that is unique among all instructions in the same function. | from Instruction |
hasMemoryResult | Holds if this instruction produces a memory result. | from Instruction |
hasOperands | Holds if this instruction’s operands are | from BinaryInstruction |
hasResultMayMemoryAccess | Holds if the memory access performed by this instruction’s result will not always write to every bit in the memory location. This is most commonly used for memory accesses that may or may not actually occur depending on runtime state (for example, the write side effect of an output parameter that is not written to on all paths), or for accesses where the memory location is a conservative estimate of the memory that might actually be accessed at runtime (for example, the global side effects of a function call). | from Instruction |
hasSortKeys | INTERNAL: Do not use. | from Instruction |
isGLValue | Holds if the result produced by this instruction is a glvalue. If this holds, the result of the instruction represents the address of a location, and the type of the location is given by | from Instruction |
isResultConflated | Holds if this is an instruction with a memory result that represents a conflation of more than one memory allocation. | from Instruction |
isResultModeled | Holds if the result of this instruction is precisely modeled in SSA. Always holds for a register result. For a memory result, a modeled result is connected to its actual uses. An unmodeled result has no uses. | from Instruction |
toString | Gets a textual representation of this element. | from Instruction |
