这是什么？pseudo register！有什么用处？debug！
完整列表如下：
Pseudoregister | Description |
@ERR | Last error value; the same value returned by the GetLastError() API function |
@TIB | Thread information block for the current thread; necessary because the debugger doesn't handle the "FS:0" format |
@CLK | Undocumented clock register; usable only in the Watch window |
@EAX, @EBX, @ECX, @EDX, @ESI, @EDI, @EIP, @ESP, @EBP, @EFL | Intel CPU registers |
@CS, @DS, @ES, @SS, @FS, @GS | Intel CPU segment registers |
@ST0, @ST1, @ST2, @ST3, @ST4, @ST5, @ST6, @ST7 | Intel CPU floating-point registers |
