在經過幾個簡單測試之后，使用system_call_table和eax中包含的索引來執行真正的系統調用了。
The code at BE allocates the memory from the heap for the Singleton object and stores a pointer to that memory in eax.
BE處的代碼為Singleton對象從堆中分配內存，并將一個指向該塊內存的指針存儲到eax中。
This table, shown in Figure 2, uses the index provided in eax to identify which system call to invoke from the table (sys_call_table).
這個表如圖2所示，使用eax中提供的索引來確定要調用該表中的哪個系統調用（sys_call_table）。
The next line, C3, takes the pointer in eax and stores it back into the instance reference at memory location 049388C8.
下一行代碼，C3，獲取eax中的指針并將其存儲回內存位置為049388C8的實例引用。
The input to cpuid (the variable "op" ) is passed to "asm" in the eax register, as cpuid expects it to.
對cpuid的輸入（變量“op”）傳遞到“asm”的eax寄存器中，因為cpuid希望它這樣做。
Larger structures are returned in the EAX register as pointers to hidden return structures.
如果是體積更大的結構體返回的話，那么EAX存放的將是一個指向結構體所在地址的指針。
A value of 1 (for the Linux exit system call) is stored in EAX to request that the program exit.
EAX中存儲的值是1（代表Linuxexit系統調用），這請求程序退出。
Thus %eax serves here as both input and output register.

在完成這一步之前，GCC假設%eax和%ecx是自由的，它可能決定將它們用作存儲其它的數據。
The first two lines of assembly code at B0 and B5 load the instance reference from memory location 049388C8 into eax and test for null.
B0和B5處的前兩行匯編代碼將instance引用從內存位置049388C8加載至eax中，并進行null檢查。
The CPU chooses the AL, AX, or EAX register depending on the width of the operand (8, 16, or 32 bits).
CPU根據操作數的寬度（8、16或32）選擇AL、AX或EAX寄存器。
While lodsl modifies %eax, the lodsl and stosl instructions use it implicitly.
當lodsl修改%eax時，lodsl和stosl指令隱含地使用它。
And here you can see another constraint that uses the two registers %eax and %edx to combine two 32-bit values and generate a 64-bit value
在下面可以看到另一個約束，它使用兩個寄存器%eax和%edx將兩個32位的值合并在一起，然后生成一個64位的值
