Public Attributes
uintb	offset
	Offset of the varnode address.
int4	size
	Size in bytes of the varnode or piece (immutable)
int4	writeop
	Index of the (last) p-code op writing to register (or -1)
int4	readop
	Index of the (last) p-code op reading the register (or -1)
int4	inslot
	Input slot of p-code op reading the register (or -1)
int4	writecount
	Number of times the register is written.
int4	readcount
	Number of times the register is read.
int4	writesection
	Section containing (last) p-code op writing to the register (or -2)
int4	readsection
	Section containing (last) p-code op reading the register (or -2)
int4	opttype
	0 = register read by a COPY, 1 = register written by a COPY (-1 otherwise)

Detailed Description

Description of how a temporary register is being used within a Constructor.

This counts reads and writes of the register. If the register is read only once, the particular p-code op and input slot reading it is recorded. If the register is written only once, the particular p-code op writing it is recorded.

Constructor & Destructor Documentation

OptimizeRecord() [1/2]

ghidra::ConsistencyChecker::OptimizeRecord::OptimizeRecord ( uintb  offset, int4  size  )

inline

Construct a record, initializing counts.

Parameters

offset	is the starting offset of the temporary range
size	is the number of bytes in the range

References inslot, offset, opttype, readcount, readop, readsection, size, writecount, writeop, and writesection.

OptimizeRecord() [2/2]

ghidra::ConsistencyChecker::OptimizeRecord::OptimizeRecord

(

vector< OptimizeRecord * > &

records

)

Constructor merging the given overlapping records into a single record.

Parameters

records

is the list of records to merge

References inslot, offset, opttype, readcount, readop, readsection, size, updateCombine(), writecount, writeop, and writesection.

Member Function Documentation

updateCombine()

void ghidra::ConsistencyChecker::OptimizeRecord::updateCombine

(

ConsistencyChecker::OptimizeRecord &

that

)

Merge another record's read and write references into this.

Parameters

that	is the other record to pull read/write info from

References inslot, readcount, readop, readsection, writecount, writeop, and writesection.

updateRead()

void ghidra::ConsistencyChecker::OptimizeRecord::updateRead	(	int4	i,
		int4	inslot,
		int4	secNum
	)

Mark this range as being read by a specific op.

Parameters

i	is the index of the op reading the range
inslot	is the input slot of the op reading the range
secNum	is the constructor section number of the op

updateWrite()

void ghidra::ConsistencyChecker::OptimizeRecord::updateWrite	(	int4	i,
		int4	secNum
	)

Mark this range as being written by a specific op.

Parameters

i	is the index of the op writing to the range
secNum	is the constructor section number of the op
