Try to evaluate the expression to an absolute value.

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.

AMDGPU target specific MCExpr operations.

Takes in a minimum of 1 argument to be used with an operation. The supported operations are:

Note

If the 'or'/'max' operations are provided only a single argument, the operation will act as a no-op and simply resolve as the provided argument.
