Predstavljen<\/a><\/noindex> izdala je alat GNU Mes 0.22<\/a><\/noindex>, koji osigurava proces bootstrappinga za GCC i omogu\u0107ava zatvoren ciklus ponovne izrade iz izvornog koda.
\nOvaj alat rje\u0161ava izazov verifikovane po\u010detne izrade kompajlera u distribucijama, prekidaju\u0107i lanac cikli\u010dne ponovne izrade (za izradu kompajlera potrebni su izvr\u0161ni datoteke ve\u0107 izgra\u0111enog kompajlera, a binarne izrade kompajlera su potencijalni izvor skrivenih zaklada, \u0161to ne omogu\u0107ava potpuno jamstvo cjelovitosti izrada iz referentnog izvornog koda).<\/p>\n

U GNU Mes nudi<\/a><\/noindex> samodostatan (self-hosting) interpreter za jezik Scheme, napisan u C-u, i najjednostavniji kompajler za jezik C (MesCC), napisan na jeziku Scheme. Oba komponenta su me\u0111usobno sastavljiva. Interpreter Scheme omogu\u0107ava izradu C kompajlera MesCC, koji zatim omogu\u0107ava izradu skra\u0107ene verzije kompajlera TinyCC<\/a><\/noindex> (tcc), \u010dije mogu\u0107nosti su ve\u0107 dovoljne za izradu GCC-a. <\/p>\n

Interpreter jezika Scheme je dovoljno kompaktan, zauzima oko 5000 redaka koda na najjednostavnijem podskupu jezika C i mo\u017ee se pretvoriti u izvr\u0161ni datoteku koriste\u0107i univerzalni prevoditelj M2-Planet<\/a><\/noindex> ili najjednostavniji C-kompajler, izra\u0111en kori\u0161tenjem samoproizvedenog assemblera hex0<\/a><\/noindex>, koji ne zahtijeva vanjske ovisnosti. Pri tome, interpreter uklju\u010duje punopravni sakuplja\u010d sme\u0107a i pru\u017ea biblioteku u\u010ditavanih modula. <\/p>\n

U novom izdanju osigurana je podr\u0161ka za ponovljive izrade koriste\u0107i kombinacije mes+mescc ili guile+mescc u distribucijama GNU Guix, Debian GNU\/Linux i NixOS. Dodana je mogu\u0107nost pokretanja Scheme-interpretera Mes u GNU Hurd, ali C-kompajler mescc jo\u0161 ne radi zbog nedostatka podr\u0161ke za potrebne sistemske pozive (na primjer, fork\/exec). Dodana je po\u010detna podr\u0161ka za stvaranje izvr\u0161nih datoteka za FreeBSD. Pobolj\u0161ana je podr\u0161ka za bootstrapping distribucije Guix samo koriste\u0107i komponente na jeziku Scheme (ljuska Gash (Guile kao ljuska) umjesto bash i Gash Core Utils umjesto coreutils, grep, sed, gzip, make, awk i tar).<\/p>\n

U narednim izdanjima o\u010dekuje se uvo\u0111enje podr\u0161ke za bootstrapping za NixOS, uklju\u010divanje bootstrappinga isklju\u010divo kori\u0161tenjem komponenti na jeziku Scheme u grani wip-bootstrap, podr\u0161ka za ARM arhitekturu, mogu\u0107nost kompilacije Mes.c koriste\u0107i M2-Planet, potpuna podr\u0161ka za Guile module, te omogu\u0107avanje rada mescc s Hurd jezgrom.<\/p>\n
