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names and moved files for this to happen - removed modules lexer & parser - removed all the unit tests (most were outdated) - added Bison, flex, and C development tools to manifest.scm - added lexer.l, a source file used by the flex utility with a functioning lexing implementation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/utils/assign-stack.scm | 15 --------------- 1 file changed, 15 deletions(-) delete mode 100644 src/modules/utils/assign-stack.scm (limited to 'src/modules/utils/assign-stack.scm') diff --git a/src/modules/utils/assign-stack.scm b/src/modules/utils/assign-stack.scm deleted file mode 100644 index 1096846..0000000 --- a/src/modules/utils/assign-stack.scm +++ /dev/null @@ -1,15 +0,0 @@ -(define-module (utils assign-stack) - #:export (make-location - get-frame-size)) - - -(define make-location) -(define get-frame-size) -(let ((dict (make-hash-table)) - (ptr 0)) - (set! make-location - (lambda (id) - (or (hash-ref dict id) - (begin (set! ptr (1+ ptr)) - (hash-set! dict id (get-frame-size)))))) - (set! get-frame-size (lambda () (* -4 ptr)))) -- cgit v1.2.3
