llvm::MCTargetExpr

Synopsis

Declared in <llvm/MC/MCExpr.h>

class MCTargetExpr
    : public MCExpr

Description

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.

Base Classes

Name	Description
`MCExpr`	Base class for the full range of assembler expressions which are needed for parsing.

Enums

Name	Description
`ExprKind`	Discriminator for concrete MCExpr subclasses.

Member Functions

Name	Description
`operator=` [deleted]	Deleted copy assignment.
`dump`	Dump this expression to stderr.
`evaluateAsAbsolute`	`evaluateAsAbsolute` overloads
`evaluateAsRelocatable`	Try to evaluate the expression to a relocatable value, i.e. an expression of the fixed form (a - b + constant).
`evaluateAsRelocatableImpl` [virtual]	Evaluate this target expression as a relocatable `Res` using `Asm.`
`evaluateAsValue`	Try to evaluate the expression to the form (a - b + constant) where neither a nor b are variables.
`evaluateKnownAbsolute`	Aggressive variant of evaluateAsRelocatable when relocations are unavailable (e.g. .fill). Expects callers to handle errors when true is returned.
`findAssociatedFragment` [virtual]	Find the fragment associated with this target expression.
`getKind`	Return the kind of this expression.
`getLoc`	Return the source location of this expression.
`inlineAssignedExpr` [virtual]	Return true if assigned expressions of this kind must be inlined.
`isEqualTo` [virtual]	Return true if this target expression equals `x.`
`printImpl` [virtual]	Print this target expression to `OS.`
`visitUsedExpr` [virtual]	Visit symbols used by this target expression via `Streamer.`

Static Member Functions

Name	Description
`classof`	Return true if `E` is a target-specific expression.
`evaluateSymbolicAdd`	Add two symbolic relocatable values, folding resolved differences when possible.

Protected Type Aliases

Name	Description
`Spec`	Relocation specifier type stored in subclass data.

Protected Member Functions

Name	Description
`MCTargetExpr` [constructor]	Construct a target-specific expression.
`~MCTargetExpr` [destructor] [virtual]	Destroy a target-specific expression.
`evaluateAsRelocatableImpl`	Evaluate this expression as a relocatable value.
`getSubclassData`	Return subclass-specific data stored in this expression.
