Hi,

The following C#-snippet:

var x = 1;
var y = 1;
if (x == y)
    Console.Write("True");

Generates this MSIL:

.locals init (
            [0] int32 x,
            [1] int32 y,
            [2] bool CS$4$0000)
L_0000: nop 
L_0001: ldc.i4.1 
L_0002: stloc.0 
L_0003: ldc.i4.1 
L_0004: stloc.1 
L_0005: ldloc.0 
L_0006: ldloc.1 
L_0007: ceq 
L_0009: ldc.i4.0 
L_000a: ceq 
L_000c: stloc.2 
L_000d: ldloc.2 
L_000e: brtrue.s L_001b
L_0010: ldstr "True"
L_0015: call void [mscorlib]System.Console::Write(string)
L_001a: nop 
L_001b: ret

Why is there two ceq calls?

Thanks

Hi, Learning MSIL is fun and all that. Understanding what is going on "under the hood" can in many ways improve how you write your code performance-wise. However, the IL that is produced by the compiler is quite verbose and does not tell the whole story since JIT will optimize away a lot of the code… >>> More
