Breaking the ABI in @radareorg is not just about changing APIs for clarity and consistency. It’s also the moment to implement new features that couldn’t be added without changing public structs like drawing backward branch lines in a separated column in the disassembly #reverseengineering #tui #cli #assembler
Tracing back #programming language history to the root of the very first (mnemonic) #GOTO instruction (jump/branch) I found two different sources:
1. In 1954 Nathanael Rochester developed the "first" mnemonic #assembler for the #IBM 701 #mainframe computer that uses "TR" jump commands: https://shrtn.escalar.pt/ZuE5
2. In 1947 the "manual" for the #Whirlwind computer contained the "sp x" mnemonic: https://shrtn.escalar.pt/FdYC
So, which one was actually the "first" to use mnemonics for branching?
"Calypsi" is a collection of compilers and assemblers that run under Windows, Linux and macOS and can generate code for various retro platforms - 6502 and 68000 processors are supported, among others. New version 5.9 has been now released:

Zachtronics (now @coincidence.games) who you may know from their great TIS-100 #assembler #programming game, also ported some of their mini-games to actual retro hardware:

Under the title link you will find a modern web application for writing, executing and learning M68K assembler code, which uses the SvelteKit framework and the Rust programming language. The tool now supports not only 68k, but also MIPS architecture:

This is pretty cool. Customasm is a sort of assembler generator for custom architectures.
You feed the tool with an instruction set description and an assembly source and it assembles the source according to the instructions. It's useful for working with bytecodes of virtual machines, FGPAs, or custom chips.
