Questo strumento affronta la questione di una compilation iniziale verificata nei pacchetti, interrompendo la catena di ricompilazione ciclica (poich\u00e9 per compilare il compilatore sono necessari file eseguibili gi\u00e0 compilati, e le versioni binarie del compilatore rappresentano una fonte potenziale di backdoor, il che non consente di garantire completamente l'integrit\u00e0 delle versioni dai sorgenti ufficiali).    <\/p>\n<p>GNU Mes offre un interprete autonomo per il linguaggio Scheme, scritto in C, e un semplice compilatore per il linguaggio C (MesCC), scritto in Scheme. Entrambi i componenti sono reciprocamente compilabili. L'interprete Scheme consente di compilare il compilatore C MesCC, che a sua volta consente di costruire una versione ridotta del compilatore TinyCC (tcc), le cui capacit\u00e0 sono gi\u00e0 sufficienti per compilare GCC.               <\/p>\n<p>L'interprete del linguaggio Scheme \u00e8 molto compatto, occupa circa 5000 righe di codice nella sottosetta pi\u00f9 semplice del linguaggio C e pu\u00f2 essere convertito in un file eseguibile utilizzando il traduttore universale M2-Planet o un semplice compilatore C, costruito utilizzando l'assemblatore auto-costruibile hex0, che non richiede dipendenze esterne. Inoltre, l'interprete include un completo garbage collector e fornisce una libreria di moduli caricabili. Il progetto sviluppa anche la libreria C Mes, sufficiente per compilare glibc 2.2.5, binutils 2.20.1 e gcc 2.95.3, necessari per il dispiegamento della distribuzione Guix per piattaforme i686-linux, x86_64-linux, armhf-linux e aarch64-linux, utilizzando solo i sorgenti (Full Source Bootstrap).          <\/p>\n<p>Nel nuovo rilascio \u00e8 stata implementata la supporto per l'architettura RISC-V (RISC-V64-linux) ed \u00e8 stata aggiunta la compilazione utilizzando il transpiler M2-Planet. \u00c8 supportata la compilazione con la versione M2-Planet 1.11.0 per la piattaforma di destinazione x86_64-linux. Non \u00e8 pi\u00f9 necessario specificare la modalit\u00e0 \u00abbootstrap-mode\u00bb durante l'utilizzo di M2-Planet. In MesCC sono stati risolti i problemi di compatibilit\u00e0 con le versioni GCC 10+, garantita l'inizializzazione dei campi delle strutture a valore 0 e ripristinata la possibilit\u00e0 di eseguire il debug dei file binari a livello di singole funzioni.        <\/p>\n<p>Nei prossimi rilasci ci si attende l'introduzione del supporto per il bootstrap di NixOS esclusivamente dai sorgenti, il supporto per moduli completamente compatibili con Guile, la possibilit\u00e0 di eseguire Gash e Gash-Utils, il supporto per il bootstrap di gcc 4.6.4, oltre alla possibilit\u00e0 di una ricompilazione completa dell'intero sistema dai sorgenti in ambienti Linux basati sulle architetture armhf e riscv64.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
