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.

Extension point for target-specific MCExpr subclasses to implement.

This can encode a relocation operator, serving as a replacement for MCSymbolRefExpr::VariantKind. Ideally, limit this to top-level use, avoiding its inclusion as a subexpression.

NOTE: All subclasses are required to have trivial destructors because MCExprs are bump pointer allocated and not destructed.
