Question

Which compiler? AFAIK, GCC and Clang write their own parser

from scratch. What PLs official implementation use parser generator? IIRC Bash, PHP. Either old-fashioned or home-made.

Parsing efficiency is important when you have several kilobytes of memory. Nowadays, human-friendly diagnostics prevails.

What's more, PLs are usually CSGs instead of CFGs. You need lots of hack to use the traditional LALR parser generator.

Why torture yourself with a parser generator when a simple and intuitive recursive descent parser works smoothly?
