someone reblog this with a grammar and a language spec and i’ll make it to the best of my ability (if multiple people do it i’ll pick my favorite)

please make it sane

(it will be recursive descent and it will likely target QBE. don’t include any metaprogramming stuff idk how to do that)

Assembly Language Counting Program

I have been learning x86 assembly language. I know a little bit from years ago but now it is coming back to me. I formerly did 16 bit DOS hobby programs. This is 32 bit Linux programming in assembly using FASM as my assembler. format ELF executable entry main main: ; the main function of our assembly function, just as if I were writing C. ; I can load any string address into eax and print…

i'm writing an entirely normal programming language

there is nothing strange or weird about my programming language it is a perfectly normal programming language with an extremely ordinary typesystem

[stvff-talks]

I'm still working on programming languages, though it has evolved quite a bit

Blogging about it should be fun

Compilers generating assembly be like:

Probably, idk, this was just the most drawable part of something I just came up with on my own when figuring out how to eliminate sequences which are tails of other sequences.

And I am sure compilers do this (or probably something strictly better) when figuring out how to "overlap" functions where one function's code is exactly the tail of another function's code. By "overlap" I mean generate and order the machine instructions so that one function just "falls off the end" into the other function's body.

I'd call this something like "tail merging" but I bet it has a more established and arguably worse name already.

in 2003 Google's build system was moved from a single Makefile to a per-directory design with better-managed, more explicit dependencies. A typical binary shrank about 40% in file size, just from having more accurate dependencies recorded.
