MesCC now compiles a less heavily patched TinyCC into a mes-tcc that in turn passes 41/69 of mescc's C tests. When mes-tcc passes all 69 tests, this almost-full-source-bootstrapped version of TinyCC should be able to compile itself. An unpatched, GNU Gcc-compiled tcc is known to compile GNU 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 compiled by M2-Planet or 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 (mescc.mes). MesCC can compile a modified TinyCC[8] that is close to being 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 ~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=3Dv0.= 11 -O mes-0.11.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 0.11 since 0.10 ** MesCC *** MesCC now compiles a mes-tcc that passes 41/69 of mescc's C tests. *** MesCC's libc can now be compiled with tcc (syscall support: write). *** MesCC now compiles a less-patched tcc: -214/+458 lines [WAS: -333/+747= ]. *** MesCC now supports empty for. *** MesCC has been greatly refactored, 500/3000 lines have been removed. *** MesCC now supports complex [struct] by value assign foo.bar, foo->bar,= foo[bar]. *** MesCC now depends on Nyacc 0.82.4.
