LLVM_ABI void dump () const
LLVM_ABI bool evaluateAsAbsolute (int64_t &Res) const
Try to evaluate the expression to an absolute value.

LLVM_ABI bool evaluateAsAbsolute (int64_t &Res, const MCAssembler *Asm) const
LLVM_ABI bool evaluateKnownAbsolute (int64_t &Res, const MCAssembler &Asm) const
Aggressive variant of evaluateAsRelocatable when relocations are unavailable (e.g.
LLVM_ABI bool evaluateAsRelocatable (MCValue &Res, const MCAssembler *Asm) const
Try to evaluate the expression to a relocatable value, i.e.
LLVM_ABI bool evaluateAsValue (MCValue &Res, const MCAssembler &Asm) const
Try to evaluate the expression to the form (a - b + constant) where neither a nor b are variables.
LLVM_ABI MCFragment * findAssociatedFragment () const
Find the "associated section" for this expression, which is currently defined as the absolute section for constants, or otherwise the section associated with the first defined symbol in the expression.
