casm

x86_64 / amd64 Instruction Set Architecture Assembler, casm is my hobby / experimental project, casm is three binary format support Raw Binary, Bootloader, and ELF64.

casm is x86_64 / amd64 Instruction Set Architecture Assembler, casm is my hobby project, I'm learn how programming language works, basically programming language convert to particular Instruction Set Architecture Assembly and assembler is read assembly and convert to particular Instruction Set Architecture machine code, Computer machine code is binary (0/1), That computer understand and process.

This assembler is not full fledged, But i'm wrote this assembler and now i'm understand how programming language work.

Build

This assembler is written in GoLang, so require GoLang, if GoLang is not install in your computer then install GoLang. Visit https://go.dev/doc/install to install GoLang.

Extract Downloaded file, and open terminal in extracted directory, and type this command in terminal

go build -o casm cmd/casm.go

If command is executed then generated casm executable file.

Hello, World!

Execute Hello, World! Assembly program using casm.

Hello, World! program is written in test_files/helloworld.asm file, assemble this file then generate Hello, World! executable file!, type this command in terminal and assemble Hello, World! assembly file

./casm test_files/helloworld.asm

Executable file is generated, file name is a.out, Execute this file using this command

./a.out

Now you can see Hello, World! in terminal!

Limitation

This assembler is not full fledged then many feature is not working like SIB, pre arithmetic operations, include statement, etcetera...
