commits over 10 weeks. MesCC now compiles a less heavily patched<br>
TinyCC into a mes-tcc that in turn passes 41/69 of mescc's C tests.<br>
<br>
When mes-tcc passes all 69 tests, this almost-full-source-<wbr>bootstrapped<br>
version of TinyCC should be able to compile itself. An unpatched, GNU<br>
Gcc-compiled tcc is known to compile GNU Gcc.<br>
<br>
* About<br>
<br>
Mes[0] aims to create full source bootstrapping for GuixSD[1] as<br>
part of the bootstrappable builds[2] project.<br>
<br>
It currently consists of a mutual self-hosting [close to Guile-]<br>
Scheme interpreter prototype in C and a Nyacc-based C compiler in<br>
[Guile] Scheme. This C prototype will be rewritten in stage0[3]<br>
M1 assembly (or compiled by M2-Planet or stage2 slow-LISP, or ...).<br>
<br>
The Scheme interpreter prototype (mes.c) has a Garbage Collector,<br>
a library of loadable Scheme modules-- notably Dominique Boucher's<br>
LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt<br>
Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely<br>
enough to support a simple REPL (repl.mes) and simple C-compiler<br>
MesCC (mescc.mes).<br>
<br>
MesCC can compile a modified TinyCC[8] that is close to being<br>
self-hosting. A GNU Ccc-compiled tcc is known[9] to compile GCC.<br>
<br>
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10]<br>
-- John McCarthy page 13, GNU Guix's source/binary packaging<br>
transparency and Jeremiah Orians's stage0 ~300 byte self-hosting<br>
hex assembler.<br>

<br>
git clone <a href="https://gitlab.com/janneke/mes" rel="noreferrer" target="_blank">https://gitlab.com/janneke/mes</a><br>

<br>
Mes runs from the source tree and can also be built, packaged and<br>
installed in Guix[SD] by the usual<br>
<br>
guix package -f guix.scm<br>

* Changes in 0.11 since 0.10<br>
** MesCC<br>
*** MesCC now compiles a mes-tcc that passes 41/69 of mescc's C tests.<br>
*** MesCC's libc can now be compiled with tcc (syscall support: write).<br>
*** MesCC now compiles a less-patched tcc: -214/+458 lines [WAS: -333/+747].<br>
*** MesCC now supports empty for.<br>
*** MesCC has been greatly refactored, 500/3000 lines have been removed.<br>
*** MesCC now supports complex [struct] by value assign foo.bar, foo->bar, foo[bar].<br>
*** MesCC now depends on Nyacc 0.82.4.<br>
