◆ tryAddingPcLoadReferenceComment()

void AMDGPUSymbolizer::tryAddingPcLoadReferenceComment	(	raw_ostream &	cStream,
		int64_t	Value,
		uint64_t	Address
	)

overridevirtual

Try to add a comment on the PC-relative load.

For instance, in Mach-O, this is used to add annotations to instructions that use C string literals, as found in __cstring.

Implements llvm::MCSymbolizer.

◆ tryAddingSymbolicOperand()

bool AMDGPUSymbolizer::tryAddingSymbolicOperand	(	MCInst &	Inst,
		raw_ostream &	cStream,
		int64_t	Value,
		uint64_t	Address,
		bool	IsBranch,
		uint64_t	Offset,
		uint64_t	InstSize
	)

overridevirtual

Try to add a symbolic operand instead of Value to the MCInst.

Instead of having a difficult to read immediate, a symbolic operand would represent this immediate in a more understandable way, for instance as a symbol or an offset from a symbol. Relocations can also be used to enrich the symbolic expression.

Parameters

Inst	- The MCInst where to insert the symbolic operand.
cStream	- Stream to print comments and annotations on.
Value	- Operand value, pc-adjusted by the caller if necessary.
Address	- Load address of the instruction.
IsBranch	- Is the instruction a branch?
Offset	- Byte offset of the operand inside the inst.
InstSize	- Size of the instruction in bytes.

Returns: Whether a symbolic operand was added.

Implements llvm::MCSymbolizer.
