Mescc now produces object files in the hex2 ascii output format compatible with the stage0 linker. Special thanks to Jeremiah Orians for support with MESCC_Tools and hex2, more goodness to follow soon! * About Mes aims to create full source bootstrapping for GuixSD: an entirely source-based bootstrap path. The target is to [have GuixSD] boostrap from a minimal, easily inspectable binary --that should be readable as source-- into something close to R6RS Scheme. 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. The Scheme interpreter prototype (mes.c) has a Garbage Collector, a library of loadable Scheme modules-- notably Dominique Boucher's LALR[1], Pre-R6RS portable syntax-case[2] with R7RS ellipsis, Matt Wette's Nyacc[3] Guile's PEG[4] --and test suite just barely enough to support a simple REPL (repl.mes) and simple C-compiler (mescc.mes) that can produce the second initial ELF binary from binary from mes.c, in only about 2h30'. Mes was inspired by The Maxwell Equations of Software: LISP-1.5[5] -- John McCarthy page 13, GNU Guix's[6] source/binary packaging transparency and Jeremiah Orians's stage0[7] bootstrap project. * Download git clone https://gitlab.com/janneke/mes wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=3Dv0.= 8 -O mes-0.8.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 0.8 since 0.7 ** Mescc *** Mescc now depends on the hex2 linker from MESCC_Tools[9]. Direct ELF output support has been removed. ELF symbol and string table creation has been removed. *** Mescc now has experimental annotation support for hex2. *** Mescc has experimental annotation support for hex2. *** Mescc has been simplified by leveraging use labels in hex2 output. *** Mescc now supports continue in loops. *** Mescc now compiles to hex2 object files. ** Language *** 1 new function list-index.
