二进制编码的十进制(BCD,Binary Coded Decimal)格式是用于处理人可读的数字常见方法,处理器中可以快速处理这种格式。 很多高级的BCD处理操作位于FPU中,但是处理器会包含一些简化的指令。我们来看下基本的BCD运算指令。 不打包BCD运算 不打包的BCD值:是一个字节中包含单个十进制位(0到9). ...
control-transfer instructions. In 64-bit mode, instructions that use ModR/M addressing can use RIP-relative addressing. Without RIP-relative addressing, all ModR/M modes address memory relative to zero. RIP-relative addressing allows specific ModR/M modes to address memory relative to the 64-bit...

Masm2c is a tool designed to translate 16-bit x86 assembly code (often used in DOS games) to C and SDL, enabling easier porting, analysis, and modification. It is aSource-to-source translatorthat generates fake-assembler instructions which can be compiled with a C compiler and executed. ...
Hopefully this repository helps someone who is learning about x86 assembly and its bytecode format. There are a few examples to get an idea of the API I was aiming for. x86-64 bytecode An x86-64 program consists of a list of instructions. All of these instructions are built with the fo...
