Prezentat<\/a><\/noindex> lansarea instrumentarului GNU Mes 0.22<\/a><\/noindex>, care asigur\u0103 procesul de bootstrap pentru GCC \u0219i permite atingerea unui ciclu \u00eenchis de recompilare din sursele originale.
\nInstrumentarul rezolv\u0103 problema construirii verificate ini\u021biale a compilatorului \u00een distribu\u021bii, \u00eentrerup\u00e2nd lan\u021bul de recompilare ciclic\u0103 (pentru construirea compilatorului sunt necesare fi\u0219iere executabile deja construite, iar versiunile binare ale compilatorului sunt surse poten\u021biale de backdoor-uri, ceea ce nu permite garantarea complet\u0103 a integrit\u0103\u021bii construc\u021biilor din sursele de referin\u021b\u0103).<\/p>\n

\u00cen GNU Mes se ofer\u0103<\/a><\/noindex> un interpret auto-suficient pentru limbajul Scheme, scris \u00een C, \u0219i un compilator simplu pentru limbajul C (MesCC), scris \u00een Scheme. Ambele componente sunt capabile s\u0103 se reconstruiasc\u0103 reciproc. Interpretul Scheme permite construirea compilatorului C MesCC, care apoi permite construirea unei versiuni reduse a compilatorului TinyCC<\/a><\/noindex> (tcc), a c\u0103rui capacitate este suficient\u0103 pentru construirea GCC. <\/p>\n

Interpretul limbajului Scheme este destul de compact, ocup\u00e2nd aproximativ 5000 de linii de cod \u00eentr-un subset simplu al limbajului C \u0219i poate fi transformat \u00eentr-un fi\u0219ier executabil folosind un translator universal M2-Planet<\/a><\/noindex> sau un compilator de baz\u0103 C, construit folosind un asamblor auto-reconstruit hex0<\/a><\/noindex>, care nu necesit\u0103 dependen\u021be externe. La aceea\u0219i vreme, interpretul include un colector de gunoi complet \u0219i ofer\u0103 o bibliotec\u0103 de module \u00eenc\u0103rcabile. <\/p>\n

\u00cen noua versiune a fost asigurat\u0103 suportul pentru construc\u021bii repetabile utiliz\u00e2nd leg\u0103turi mes+mescc sau guile+mescc \u00een distribu\u021biile GNU Guix, Debian GNU\/Linux \u0219i NixOS. A fost ad\u0103ugat\u0103 posibilitatea de a rula interpretul Scheme Mes \u00een GNU Hurd, \u00eens\u0103 compilatorul C mescc nu func\u021bioneaz\u0103 \u00eenc\u0103 din cauza lipsei suportului pentru apelurile de sistem necesare (de exemplu, fork\/exec). A fost ad\u0103ugat suport ini\u021bial pentru crearea fi\u0219ierelor executabile FreeBSD. Suportul pentru bootstrapping-ul distribu\u021biei Guix a fost \u00eembun\u0103t\u0103\u021bit folosind doar componente \u00een limbajul Scheme (shell-ul Gash (Guile as Shell) \u00een loc de bash \u0219i Gash Core Utils \u00een loc de coreutils, grep, sed, gzip, make, awk \u0219i tar).<\/p>\n

Urm\u0103toarele versiuni vor aduce suport pentru bootstrapping pentru NixOS, activarea bootstrapping-ului folosind doar componente \u00een limbajul Scheme \u00een ramura wip-bootstrap, suport pentru arhitectura ARM, posibilitatea de a compila Mes.c folosind M2-Planet, suport complet pentru modulele Guile, asigurarea func\u021bion\u0103rii mescc cu nucleul Hurd.<\/p>\n
