Detailed Description

An operation that writes to volatile memory.

This CALLOTHER p-code operation takes as its input parameters:

Member Function Documentation

◆ extractAnnotationSize()

int4 ghidra::VolatileWriteOp::extractAnnotationSize ( const Varnode vn,
const PcodeOp op 
)
virtual

Assign a size to an annotation input to this userop.

Assuming an annotation refers to a special symbol accessed by this operation, retrieve the size (in bytes) of the symbol, which isn't ordinarily stored as part of the annotation.

Parameters
vnis the annotation Varnode
opis the specific PcodeOp instance of this userop

Reimplemented from ghidra::UserPcodeOp.

References ghidra::PcodeOp::getIn(), and ghidra::Varnode::getSize().

◆ getOperatorName()

string ghidra::VolatileWriteOp::getOperatorName ( const PcodeOp op) const
virtual

Get the symbol representing this operation in decompiled code.

This will return the symbol formally displayed in source code, which can be tailored more than the low-level name

Parameters
opis the operation (in context) where a symbol is needed
Returns
the symbol as a string

Reimplemented from ghidra::UserPcodeOp.
