Subject: Mes 0.10 released
|
|
|
|
I am pleased to announce the release of Mes 0.10, representing 82
|
|
commits over 6 weeks. Mescc now compiles a bootstrappable-modified
|
|
TinyCC into a mes-tcc that in turn can successfully compile a trivial
|
|
C program.
|
|
|
|
* 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] that is
|
|
starting to 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=v0.10 -O mes-0.10.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 0.10 since 0.9
|
|
** Core
|
|
*** 2 new functions
|
|
logand, lognot.
|
|
** Mescc
|
|
*** Mes now includes M1 sources for full source bootstrapping up to tcc.
|
|
*** Mescc now depends on Nyacc 0.81.0.
|
|
*** Mescc now compiles a mes-tcc that compiles a trivial C to a running a.out.
|
|
*** Mescc now supports several (as used my tinycc) struct by value assignments.
|
|
*** Mescc now has _start in a separate crt1.c.
|
|
*** Mescc now supports initializer arithmetic.
|
|
*** Mescc now supports arrays of struct of arbitrary size.
|
|
*** Mescc now supports pointer arithmetic.
|
|
*** Mescc now defines __i386__, __linux__.
|
|
*** Mescc now supports --*p, ++*p.
|
|
*** Mescc now supports int foo[bar] = {baz,...}.
|
|
*** Mescc now supports \x00 in strings in M1.
|
|
*** Mescc now supports complex enum expressions. Thanks, rain1!
|
|
*** Mescc now supports short.
|
|
*** Mescc now supports foo.bar = foo.baz = bla.
|
|
*** Mescc now supports foo = bar < baz and comparison permutations.
|
|
*** Mescc now supports (anonymous) structs in unions.
|
|
*** Mescc now writes M1 strings if possible.
|
|
**** 2 improved mlibc functions
|
|
malloc, realloc.
|
|
**** 13 new mlibc functions
|
|
fclose, fgetc, fprintf, fwrite, memcpy, memmove, memset, snprintf, strcat,
|
|
strchr, strrchr, strtoull, vnsprintf.
|
|
**** 15 new tinycc-support tests
|
|
76-pointer-arithmetic.c, 77-pointer-assign.c, 78-union-struct.c,
|
|
79-int-array.c, 7a-struct-char-array.c, 7b-struct-int-array.c,
|
|
7c-dynarray.c, 7d-cast-char.c, 7e-struct-array-access.c,
|
|
7f-struct-pointer-arithmetic.c, 7g-struct-byte-word-field.c,
|
|
7h-struct-assign.c, 7i-struct-struct.c, 7j-strtoull.c,
|
|
7k-for-each-elem.c.
|
|
** Noteworthy bug fixes
|
|
*** Mescc has many fixes for foo.bar[baz], foo[bar].baz with ./-> permutations.
|
|
*** Many bugs and limitations in mescc have been fixed and removed.
