Detailed Description

An INS represents an instruction. Can only be accessed at instrumentation time.

Iteration idioms:

// Forward pass over all instructions in bbl
for( INS ins= BBL_InsHead(bbl); INS_Valid(ins); ins = INS_Next(ins) )
// Forward pass over all instructions in routine
for( INS ins= RTN_InsHead(rtn); INS_Valid(ins); ins = INS_Next(ins) )
BBL_InsHead
INS BBL_InsHead(BBL bbl)
Returns the first instruction of the BBL.
INS_Valid
BOOL INS_Valid(INS ins)
Checks if the instruction is valid.
INS_Next
INS INS_Next(INS ins)
Returns the instruction that follows this instruction.
RTN_InsHead
INS RTN_InsHead(RTN rtn)
Returns the first instruction of the RTN, or INS_Invalid() if no instructions.
