Prints the address of every instruction that is executed.

This tool is useful for understanding the control flow of a program for debugging, or in processor design when simulating an instruction cache.

IARG_INST_PTR

IARG_INST_PTR : Type: ADDRINT. The address of the instrumented instruction. This value does not change at IPOINT_AFTER. This is simply shorthand for IARG_ADDRINT, INS_Address.
