Function Documentation

void InstructionCountAnnotator::annotate	(	SgNode *	proj,
		const std::string &	instfile
	)

this version reads a file of the format "addrInHex \t execCount\n" for example generated by pin

Annotates each SgAsmInstruction with a number indicating how often this instruction was executed

the needed pin tool which generates this file can be found in util/pin/my_itrace.cpp

Parameters:

	proj	the (binary) SgProject to annotate
	instfile	path of file with pairs of address - execCount format "addressInHex \t count \n" can for example be generated by intel-pin

void InstructionCountAnnotator::annotate	(	SgNode *	proj,
		std::vector< std::string >	args
	)

this version runs the executable and inserts breakpoint at every instruction (ptrace)

Annotates each SgAsmInstruction with a number indicating how often this instruction was executed

Parameters:

	proj	the (binary) SgProject to annotate
	args	array with parameters for the process to trace (only parameter i.e. args[0] is NOT the exec name
