VOID LEVEL_PINCLIENT::INS_Delete (  INS  ins  )

Delete the instruction Availability: Mode: JIT O/S: Linux, Windows & MacOS CPU: All

VOID LEVEL_PINCLIENT::INS_InsertDirectJump (  INS  ins, IPOINT  ipoint, ADDRINT  tgt )

Insert direct jump instruction relative to the given instruction When used with INS_Delete it can be used to emulate control transfer instructions. Parameters: [in]  ins  input instruction [in]  ipoint  location relative to ins (only IPOINT_BEFORE and IPOINT_AFTER are supported) [in]  tgt  absolute address of the target Availability: Mode: JIT O/S: Linux, Windows & MacOS CPU: IA-32 and Intel(R) 64 architectures

VOID LEVEL_PINCLIENT::INS_InsertIndirectJump (  INS  ins, IPOINT  ipoint, REG  reg )

Insert indirect jump instruction relative to the given instruction. When used with INS_Delete it can be used to emulate control transfer instructions. Parameters: [in]  ins  input instruction [in]  ipoint  location relative to ins (only IPOINT_BEFORE and IPOINT_AFTER are supported) [in]  reg  register holding the target Availability: Mode: JIT O/S: Linux, Windows & MacOS CPU: IA-32 and Intel(R) 64 architectures

BOOL LEVEL_PINCLIENT::INS_RewriteMemoryAddressingToBaseRegisterOnly (  INS  ins, MEMORY_TYPE  mtype, REG  newBase )

Change this memory access instruction use a base register addressing mode. On IA-32/Intel64, it will not rewrite all references; See INS_IsRewritableMemOpBase() for details. Parameters: [in]  ins  input instruction [in]  mtype  contols which operand to rewrite (read, write or second read operand) [in]  newBase  register used as the new memory base address Availability: Mode: JIT O/S: Linux, Windows & MacOS CPU: IA-32 and Intel(R) 64 architectures
