Application for testing the correctness of "INS_MemoryDisplacement(INS ins)".
|
|
INS_MemoryDisplacement computes the memory displacement, which is a sign number.
|
|
Tested only on 64 Linux architecture.
|
|
When running the application with the tool: "memory_displacement.cpp", the output, which is the displacement value, should be -24.
|
|
When running the application natively( without the tool), the output for the IA-32 architecture, which is the displacement value, should be 4.
|
|
When running the application natively( without the tool), the output for the IA-32 architecture, which is the displacement value, should be 7.
