IL代码,
cpp
.assembly extern mscorlib {}
.assembly Test
{
.ver 1:0:1:0
}
.module test.exe
.method static void main() cil managed
{
.maxstack 8
.entrypoint
.locals init (int32, int32)
ldc.i4 4
stloc.0 //Upper limit of the Loop, total 5
ldc.i4 0
stloc.1 //Initialize the Starting of loop
Start:
//Check if the Counter exceeds
ldloc.1
ldloc.0
bgt Exit //If Second variable exceeds the first variable, then exit
ldloc.1
call void [mscorlib]System.Console::WriteLine(int32)
//Increase the Counter
ldc.i4 1
ldloc.1
add
stloc.1
br Start
Exit:
ret
}
构建运行如下;
我还不是太理解,循环的开始和结束值是不是装入栈;循环变量加1也是在栈上操作;循环中啥也没干,只是输出了循环变量值;bgt、br是跳转语句;有时间继续;
