After a year of development, the release of GNU Mes 0.23 has taken place, providing the bootstrapping process for GCC and enabling a closed-loop rebuild cycle from source texts. The tool addresses the challenge of a verified initial compiler build in distributions, breaking the chain of cyclical rebuilding (since compiling a compiler requires executables from an already built compiler, and binary builds can potentially harbor hidden backdoors, which does not allow for a complete guarantee of integrity from the reference source texts). <\/p>\n
GNU Mes offers a self-hosting interpreter for the Scheme language, written in C, and a basic compiler for C (MesCC), written in Scheme. Both components are mutually buildable. The Scheme interpreter allows building the C compiler MesCC, which can then compile a stripped-down version of TinyCC (tcc), whose capabilities are sufficient for building GCC. <\/p>\n
The Scheme language interpreter is quite compact, consisting of about 5000 lines of code in the simplest subset of the C language, and can be transformed into an executable file using the universal translator M2-Planet or a simple C compiler built with the self-hosting assembler hex0, which requires no external dependencies. Additionally, the interpreter includes a full garbage collector and provides a library of loadable modules. <\/p>\n
The new release introduces support for ARM architecture (armhf-linux and aarch-linux). It adds the capability to use Mes along with a reduced set of bootstrap files from the GNU Guix project (GNU Guix Reduced Binary Seed). Support for compiling Mes and the Mes C library using GCC 10.x has been implemented. The MesCC compiler now includes its own library libmescc.a (-lmescc), and when compiling with GCC, the flag «-lgcc» is now specified. Support for compiling MesCC with Guile 3.0.x has been ensured. \n Source: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
