xocc – C compiler based on BSD license

In plain words

xocc is a C compiler built on the XOC infrastructure, featuring the XGEN code generator and XOCFE C frontend, all under BSD license. It provides multi-level intermediate representations (IRs) and comprehensive compilation tools including control flow analysis, alias analysis, and optimization techniques like dead code elimination, copy propagation, and global value numbering. The compiler is designed for developers needing a flexible, feature-rich compilation framework with support for multiple language representations.

  Repo: https://github.com/valdanylchuk/xcc700 Hi Everyone! I just wrote my first compiler! - single pass, recursive descent, direct emission - generates REL ELF binaries, runnable using ESP-IDF elf_loader - very basic features only, just enough for self-hosting - treats the Xtensa CPU as a stack machine for simplicity, no register allocation / window usage - compilable on Mac, probably also Linux, can cross-compile for esp32 there - wrote for fun / cyberdeck project Sample output from esp32: xcc700.elf xcc700.c -o /d/cc.elf [ xcc700 ] BUILD COMPLETED >…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
