Bootstrap: the Finch compiler written in Finch

Browse source

boot/ is a second Finch compiler written in Finch (lexer, parser, type checker and
an LLVM IR text generator, ~3k lines). Built by the C++ compiler it compiles itself;
stage 2 and stage 3 produce byte-identical IR. It covers the core language: functions,
structs, arrays, str, pointers, loops and modules (no C imports, sized numbers or defer),
copies values like the main compiler and leaves freeing memory to the operating system.

tests/boot.sh checks the fixpoint and runs the test programs it supports.
Also: shell(cmd) built-in.
