Hi Kashyap, > What would you recommend if I had to write an assembler for RISC V? Can I > look at llvm.l in pil21 or should I look at lib/asm.l in pil64?
I would say that lib/asm.l is the way to go. It maps directly to a target assembly language (or C in case of 'emu'). llvm is a different, special machinery. > I mean, I could always write a program that takes the assembly as a text > file input and parses it - but where's the fun in that? ...

It not only uses the reader, but the whole interpreter, and simply *redefines* all needed functions (like 'de', 'let', 'if', 'cond', 'while', 'car', 'cdr' and many many more) in a 'llvm' namespace, so that they compile LLVM-IR code instead of executing something. This is well in the tradition of Forth compilers. ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
