Detailed Description

Function Documentation

BBL_Address()

ADDRINT BBL_Address

(

BBL

bbl

)

Returns

Address of a bbl

Availability:

Mode: JIT & Probe
O/S: Linux, Windows & macOS*
CPU: All

BBL_HasFallThrough()

BOOL BBL_HasFallThrough

(

BBL

bbl

)

Refer to INS_HasFallThrough for checking if an instruction could have a fall-through path based on the opcode.

Returns

TRUE if the BBL has a fall-through bbl within the trace, else returns FALSE.

BBL_InsertCall()

VOID BBL_InsertCall	(	BBL	bbl,
		IPOINT	action,
		AFUNPTR	funptr,
			...
	)

Insert call relative to a bbl.

Parameters

bbl	BBL: Single entrance, single exit sequence of instructions to instrument
action	Specifies before, after, etc. IPOINT_BEFORE is always valid for all BBLs. IPOINT_AFTER is valid only when a fall-through exists. Can only be used if BBL_HasFallThrough is true. IPOINT_ANYWHERE will put the instrumentation at a place inside the bbl for best performance. IPOINT_TAKEN_BRANCH is valid only when the BBL ends with a control-flow instruction. Can only be used if INS_IsValidForIpointTakenBranch(BBL_ins_tail(bbl)) is true.
funptr	Analysis function to call
...	IARG_TYPE. Arguments to pass to funptr

Availability:

Mode: JIT
O/S: Linux, Windows & macOS*
CPU: All

BBL_InsertIfCall()

VOID BBL_InsertIfCall	(	BBL	bbl,
		IPOINT	action,
		AFUNPTR	funptr,
			...
	)

Insert a call to funptr relative to a BBL. If funptr returns a non-zero ADDRINT, then the immediately following "then" analysis call is executed. Note that if CALL_ORDER is used, Both "if" and "then" analysis calls must have the same order.

Parameters

bbl	BBL to instrument
action	Specifies when the analysis call executes. See the documentation in BBL_InsertCall().
funptr	Analysis function to call. Its return type must be ADDRINT
...	IARG_TYPE. Arguments to pass to funptr

Availability:

Mode: JIT
O/S: Linux, Windows & macOS*
CPU: All

BBL_InsertThenCall()

VOID BBL_InsertThenCall	(	BBL	bbl,
		IPOINT	action,
		AFUNPTR	funptr,
			...
	)

Insert a call to funptr relative to a BBL. The function is called only if the immediately preceding "if" analysis call returns a non-zero value. Note that if CALL_ORDER is used, Both "if" and "then" analysis calls must have the same order.

Parameters

bbl	BBL to instrument
action	Specifies when the analysis call executes. See the documentation in BBL_InsertCall().
funptr	Analysis function to call
...	IARG_TYPE. Arguments to pass to funptr
