bool | evaluateAsAbsolute (int64_t &Res, const MCAssembler *Asm) const |
bool | evaluateKnownAbsolute (int64_t &Res, const MCAssembler &Asm) const |
Aggressive variant of evaluateAsRelocatable when relocations are unavailable (e.g. | |
bool | evaluateAsRelocatable (MCValue &Res, const MCAssembler *Asm, const MCFixup *Fixup) const |
Try to evaluate the expression to a relocatable value, i.e. | |
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. | |
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. | |
