Subject: Mes 0.9 released
|
|
|
|
I am pleased to announce the release of Mes 0.9, representing 107
|
|
commits over 5 weeks. Mescc now compiles to a surprisingly readable
|
|
stage0 M1 macro assembler output format. Mescc now compiles a
|
|
modified TinyCC into a running [mostly segfaulting] executable. This
|
|
is a major milestone as tcc can compile GCC.
|
|
|
|
|
|
* About
|
|
|
|
Mes[0] aims to create full source bootstrapping for GuixSD[1] as
|
|
part of the bootstrappable builds[2] project.
|
|
|
|
It currently consists of a mutual self-hosting [close to Guile-]
|
|
Scheme interpreter prototype in C and a Nyacc-based C compiler in
|
|
[Guile] Scheme. This C prototype will be rewritten in stage0[3]
|
|
M1 assembly (or possibly stage2 slow-LISP, or ...).
|
|
|
|
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
|
|
a library of loadable Scheme modules-- notably Dominique Boucher's
|
|
LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
|
|
Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
|
|
enough to support a simple REPL (repl.mes) and simple C-compiler
|
|
(mescc.mes).
|
|
|
|
The simple C compiler can compile a modified TinyCC[8]. This
|
|
needs more work. A gcc-compiled tcc is known[9] to compile GCC.
|
|
|
|
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10]
|
|
-- John McCarthy page 13, GNU Guix's source/binary packaging
|
|
transparency and Jeremiah Orians's stage0 ~300 byte self-hosting
|
|
hex assembler.

|
|
* Download
|
|
|
|
git clone https://gitlab.com/janneke/mes
|
|
|
|
wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.9 -O mes-0.9.tar.gz
|
|
|
|
Mes runs from the source tree and can also be built, packaged and
|
|
installed in Guix[SD] by the usual
|
|
|
|
guix package -f guix.scm
|
|
|
|
* Changes in 0.9 since 0.8

** Core
|
|
*** Mes now builds better in non-Guix[SD] legacy distros/environments. Thanks, rain1!
|
|
** Mescc
|
|
*** Mescc now compiles a modified tinycc into a running [mostly segfaulting] tcc.mes.
|
|
https://gitlab.com/janneke/tinycc branch wip-mescc.
|
|
*** Mescc now supports locals stack frame larger than 1 byte offset.
|
|
*** Mescc now supports incomplete struct initializers {0}.
|
|
*** Mescc now supports >>=, <<=, ^=, ~.
|

|
|
*** Mescc now supports unions.
|
|
*** Mescc now supports arrays in structs.
|
|
*** Mescc now supports structs in structs.
|
|
*** Mescc has been refactored to use records.
|
|
*** Mescc now builds and runs with Guile-2.0 (legacy distro support, not recommended).
|
|

|
|
*** Mescc now has an incremental test suite consisting of 56 tests.
|
|
*** Mescc now supports stdarg variable argument lists.
|
|
