From 9e09767e23a4edb6b31540195bfe885f83e080d7 Mon Sep 17 00:00:00 2001 From: bd Date: Tue, 28 Jan 2025 14:39:47 -0500 Subject: [Ongoing] Rewrite frontend to use Flex/Bison This is a merge of another experiment, so the changes are large: - separated "modules" directory into frontend/backend - adjusted module names and moved files for this to happen - removed modules lexer & parser - removed all the unit tests (most were outdated) - added Bison, flex, and C development tools to manifest.scm - added lexer.l, a source file used by the flex utility with a functioning lexing implementation - added parser.y, a source file used by the bison utility with a functioning parser implementation - added node.c and node.h, which parser.y uses to construct an AST of a C source file (up to binary ops) - added driver.c, a Guile-C interface that provides a module to scheme programs - added a Makefile to make all of this - added stuff to .gitignore --- src/modules/generator/assembly.scm | 18 ------------------ 1 file changed, 18 deletions(-) delete mode 100644 src/modules/generator/assembly.scm (limited to 'src/modules/generator/assembly.scm') diff --git a/src/modules/generator/assembly.scm b/src/modules/generator/assembly.scm deleted file mode 100644 index 55eaaed..0000000 --- a/src/modules/generator/assembly.scm +++ /dev/null @@ -1,18 +0,0 @@ -(define-module (generator assembly) - #:use-module (ast ir) - #:use-module (utils assign-stack) - #:use-module (utils merge-instructions) - #:export (instrs - mov)) - - -(define (instrs lst) - (cons 'list (cons (list 'alloc (abs (get-frame-size))) - (merge-instr lst)))) - -(define (mov src dst) - (if (and (eq?
