Detailed Description

Check for duplicate hashes in functions: duplicate hash

All functions in the architecture/program are decompiled, and for each a check is made for Varnode pairs with identical hash values.

Member Function Documentation

◆ check()

void ghidra::IfcDuplicateHash::check	(	Funcdata *	fd,
		ostream &	s
	)

static

Check for duplicate hashes in given function.

For each duplicate discovered, a message is written to the provided stream.

Parameters

fd	is the given function to search
s	is the stream to write messages to

◆ execute()

void ghidra::IfcDuplicateHash::execute ( istream & s )

virtual

Execute this command. Additional state can be read from the given command line stream. Otherwise, the command gets its data from its registered IfaceData object

Parameters
