LLVM_ABI StringRef getValueAsString() const

Return the attribute's value as a string.

bool isValid() const

Return true if the attribute is any kind of attribute.

bool hasCalls() const

Return true if the current function has any function calls.

MachineFrameInfo & getFrameInfo()

getFrameInfo - Return the frame info object for the current function.

Function & getFunction()

Return the LLVM function that this machine code represents.

StringRef - Represent a constant reference to a string, i.e.

A switch()-like statement whose cases are string literals.

#define llvm_unreachable(msg)

Marks that the current location is not supposed to be reachable.

This is an optimization pass for GlobalISel generic memory operations.
