Functions

BOOL LEVEL_CORE::INS_IsCacheLineFlush (INS ins)
BOOL LEVEL_PINCLIENT::INS_IsAddedForFunctionReplacement (INS ins)

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) )

Function Documentation

BOOL LEVEL_PINCLIENT::INS_IsAddedForFunctionReplacement INS  ins  ) 
 

Return TRUE if ins is not an original instruction in the application, but is an instruction added by Pin for doing function replacement. Pin allows you to even instrument these non-original instructions in JIT mode.

Availability:
Mode: JIT & Probe
