* Description: Program to validate the x86 emulator library for
|
||
|
|
* correctness. We run the emulator primitive operations
|
||
|
|
* functions against the real x86 CPU, and compare the result
|
||
|
|
* and flags to ensure correctness.
|
||
|
|
*
|
||
|
|
* We use inline assembler to compile and build this program.
