Remove lex file duplication #127

Open SamuelmsWong-zz opened 5 years ago

SamuelmsWong-zz commented 5 years ago

lex-hitachi-sh.c and lex-riscv.c differ only in the tokens for their assembly instructions, so the rest (tokens for Sunflower commands and the lexical analyser function) is all duplicated.

One approach would be to split off the common %token T_* at the start of the .ys into a sf-common-tokens.y and to similarly split off the common grammar rules into a sf-common-grammar.y. @SamuelmsWong @rjlv2 @jan-heck : if any of you are interested...

Hi. I can probably get started on this in a few weeks.
