I used C for my own just in time compiler because I wanted to learn C. I still don't "know" C or what's a customary way of doing things because I only started with C code by Martin Jacob that executes machine code in a memory buffer ( https://gist.github.com/martinjacobd/3ee56f3c7b7ce621034ec3ecbc8e13f1/fe7e78b89e1581ff15c4d2797662516f281a33bd https://gist.github.com/martinjacobd/3ee56f3c7b7ce621034ec3e... ) and some Perl Compatible Regular Expression library example C file. I want to know C enough that I can create good APIs in it and transpile to C effectively because I want to take advantage of LLVM and gcc optimising backends.
