InstructionValue

Functions in this group relate to the inspection and manipulation of individual instructions.

In the C++ API, an instruction is modeled by llvm::Instruction. This class has a large number of descendents. llvm::Instruction is a llvm::Value and in the C API, instructions are modeled by LLVMValueRef.

This group also contains sub-groups which operate on specific llvm::Instruction types, e.g. llvm::CallInst.

Functions

asUser UserValue asUser(): Undocumented in source. Be warned that the author may not have intended to support it.
asValue auto asValue(): Undocumented in source. Be warned that the author may not have intended to support it.
clone InstructionValue clone(): Create a copy of 'this' instruction that is identical in all ways except the following: * The instruction has no parent * The instruction has no name
eraseFromParent void eraseFromParent(): Remove and delete an instruction.
hasMetadata bool hasMetadata(): Determine whether an instruction has any metadata attached.
intPredicate LxIntPredicate intPredicate(): Obtain the predicate of an instruction.
metadata MetadataNodeValue metadata(uint kind): Return metadata associated with an instruction value.
nextInstr Nullable!InstructionValue nextInstr(): Obtain the instruction that occurs after the one specified.
opcode LxOpcode opcode(): Obtain the code opcode for an individual instruction.
parent BasicBlock parent(): Obtain the basic block to which an instruction belongs.
prevInstr Nullable!InstructionValue prevInstr(): Obtain the instruction that occurred before this one.
realPredicate LxRealPredicate realPredicate(): Obtain the float predicate of an instruction.
removeFromParent void removeFromParent(): Remove and delete an instruction.
setMetadata void setMetadata(uint kind, Value v): Set metadata associated with an instruction value.
