I am pleased to announce the release of Mes 0.14, representing 98
commits over 4 weeks. Mes+MesCC now compiles a self-hosting TinyCC
that has only been slightly patched.
This means that we can now build a tcc that depends only on a 1MB
ASCII M1 seed. GuixSD currently uses a ~250MB binary seed to build
gcc.
Next targets are: build gcc using this almost full-source bootstrapped
tcc, and reduce the 1MB ASCII M1 seed to ~100KB of M2 source, which is
a restricted subset of C.
Packages are available from Guix's wip-bootstrap branch.
* About
Mes[0] aims to help create full source bootstrapping for GuixSD[1]
as part of the bootstrappable builds[2] project.
It currently consists of a mutual self-hosting Scheme interpreter
prototype in C and a Nyacc-based C compiler in Scheme. This C
prototype is being simplified to be transpiled by M2-Planet[3].
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+MesCC can compile an only slightly patched TinyCC[8] that is
self-hosting. A GNU Ccc-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[11] ~300 byte self-hosting
hex assembler.
* Download
git clone https://gitlab.com/janneke/mes
wget https://gitlab.com/janneke/mes/-/archive/v0.14/mes-0.14.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 0.14 since 0.13
** Core
*** Bootstrapped Mes+MesCC now compiles a tcc that is self-hosting and only slightly patched.
*** The reader now supports binary numbers (previously: read as decimal).
*** String port support has been moved to C.
*** The build has been simplified, the Make-in-Scheme experiment has been removed.
*** 2 new functions
chmod, logxor.
** Language
*** Mes now supports define-immutable-record-type and single set-field from srfi-9 gnu.
*** 12 new functions
basename, chmod, const, delete-duplicates, logxor, string-contains,
string-map, string-replace, string-trim, string-trim-both,
string-trim-right, unfold.
** MesCC
*** MesCC now supports standalone usage of nestedly defined enums, structs and unions.
*** MesCC now supports comparison of unsigned and promotion of signed/unsigned -> unsigned.
*** MesCC now supports sign extension for char, short.
*** MesCC now has stubbing for floats; compiling works, data is fu.
*** MesCC now has full suport for switch case, e.g. with default as first clause.
*** MesCC now supports destruction of casted expressions: ((struct foo*)p)->bar.
*** MesCC now has full support for pre/post, e.g.: (foo--)->bar and permutations.
*** MesCC now supports sizeof any expression or type.
*** MesCC now supports initialization of anonymous unions.
*** MesCC now supports bit fields.
*** MesCC now supports valued functions in expressions: destruction and dereferencing.
*** MesCC now supports function-static variables.
*** MesCC now supports initializer lists in structs and unions.
*** MesCC now has full support for heterogeneous variable declarations, e.g.: char p, *x = "foo", buf[3];
**** 4 new functions
__lshrdi3, __ashldi3, __ashrdi3, strncpy.
**** 9 new mlibc stubs
__fixdfdi, __fixsfdi, __fixunsxfdi, __fixxfdi, __floatundixf, ldexp,
strtod, strtof, strtold.
