ilasmでstack machine その50

概要

ilasmでstack machineやってみた。
練習問題やってみた。

練習問題

readlineを使え。

サンプルコード

.assembly extern mscorlib {
	.ver 4:0:0:0
	.publickeytoken = (B7 7A 5C 56 19 34 E0 89)
}
.assembly 'Program' {
	.custom instance void class [mscorlib]System.Runtime.CompilerServices.CompilationRelaxationsAttribute::'.ctor'(int32) =  (01 00 08 00 00 00 00 00)
	.custom instance void class [mscorlib]System.Runtime.CompilerServices.RuntimeCompatibilityAttribute::'.ctor'() =  (01 00 01 00 54 02 16 57 72 61 70 4E 6F 6E 45 78 63 65 70 74 69 6F 6E 54 68 72 6F 77 73 01)
	.custom instance void class [mscorlib]System.Diagnostics.DebuggableAttribute::'.ctor'(valuetype [mscorlib]System.Diagnostics.DebuggableAttribute/DebuggingModes) =  (01 00 07 01 00 00 00 00)
	.hash algorithm 0x00008004
	.ver  0:0:0:0
}
.namespace SBRL.Demo.Disassembly {
	.class private auto ansi beforefieldinit Program extends [mscorlib]System.Object {
		.method public static hidebysig default void Main (string[] args) cil managed {
			.entrypoint
			.maxstack 5
			.locals init (int32 V_0, int32 V_1)
			call 	string class [mscorlib]System.Console::ReadLine()
			call 	int32 int32::Parse(string)
			stloc.0
			ldc.i4.s 0x0a
			stloc.1
			ldstr 	"{0} + {1} = {2}"
			ldloc.0
			box 	[mscorlib]System.Int32
			ldloc.1
			box 	[mscorlib]System.Int32
			ldloc.0
			ldloc.1
			add
			box 	[mscorlib]System.Int32
			call 	void class [mscorlib]System.Console::WriteLine(string, object, object, object)
			ret
		} 
		.method public hidebysig specialname rtspecialname instance default void '.ctor' () cil managed {
			.maxstack 8
			ldarg.0
			call 	instance void object::'.ctor'()
			ret
		}
	}
}
