Esta ferramenta resolve a tarefa da constru\u00e7\u00e3o inicial verificada do compilador em distribui\u00e7\u00f5es, rompendo a cadeia de recompila\u00e7\u00e3o c\u00edclica (\u00e9 necess\u00e1rio ter arquivos execut\u00e1veis de um compilador j\u00e1 constru\u00eddo para compilar o novo compilador, e as compila\u00e7\u00f5es bin\u00e1rias de um compilador podem esconder backdoors, o que impede a garantia completa da integridade das compila\u00e7\u00f5es a partir dos c\u00f3digos-fonte de refer\u00eancia).    <\/p>\n<p>O GNU Mes oferece um interpretador autocontido (self-hosting) para a linguagem Scheme, escrito em C, e um compilador simples para a linguagem C (MesCC), escrito em Scheme. Ambos os componentes s\u00e3o mutuamente compil\u00e1veis. O interpretador de Scheme permite a compila\u00e7\u00e3o do compilador C MesCC, que, por sua vez, permite compilar uma vers\u00e3o reduzida do compilador TinyCC (tcc), cujas funcionalidades j\u00e1 s\u00e3o suficientes para compilar o GCC.               <\/p>\n<p>O interpretador de Scheme \u00e9 muito compacto, ocupando cerca de 5000 linhas de c\u00f3digo em um subconjunto simples da linguagem C e pode ser convertido em um arquivo execut\u00e1vel usando o tradutor universal M2-Planet ou um compilador C simples, que \u00e9 compilado usando o montador autocontido hex0, que n\u00e3o requer depend\u00eancias externas. O interpretador inclui um coletor de lixo completo e fornece uma biblioteca de m\u00f3dulos carreg\u00e1veis. O projeto tamb\u00e9m desenvolve a biblioteca C Mes, que \u00e9 suficiente para compilar o glibc 2.2.5, binutils 2.20.1 e gcc 2.95.3, necess\u00e1rios para o deployment do Guix nas plataformas i686-linux, x86_64-linux, armhf-linux e aarch64-linux, usando apenas os c\u00f3digos-fonte (Bootstrap Completo).          <\/p>\n<p>Nesta nova vers\u00e3o, foi retomado o suporte para executar o Mes no ambiente GNU Hurd. Novos m\u00f3dulos foram adicionados: rnrs (aritm\u00e9tica bit a bit) e srfi (srfi-39). Para compatibilidade com o Guile, o m\u00f3dulo srfi \u00e9 carregado por padr\u00e3o. Novas fun\u00e7\u00f5es foram adicionadas: pair-for-each e with-fluids*. O compilador MesCC agora suporta m\u00f3dulos para a gera\u00e7\u00e3o de parsers e analisadores l\u00e9xicos NYACC das vers\u00f5es 0.99.0 a 1.09.4. A possibilidade de usar m\u00f3dulos obsoletos no estilo mes para NYACC e MesCC foi removida.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
