Til implementering i Fedora 33 er planlagt<\/a><\/noindex> \u00e6ndringen<\/a><\/noindex> regler for anvendelse af compilatorer i distributionen, hvorefter compilatoren til pakkeopbygning kan v\u00e6lges afh\u00e6ngigt af anbefalinger og pr\u00e6ferencer fra hovedprojektet (upstream). I \u00f8jeblikket er det i Fedora strengt fastlagt at bruge GCC til at opbygge alle pakker, med undtagelse af tilf\u00e6lde hvor pakken kun kan opbygges i Clang\/LLVM.<\/p>\n

Motive for at give mulighed for opbygning ved hj\u00e6lp af Clang er, at nogle projekter, s\u00e5som Firefox<\/a><\/noindex> og Chromium<\/a><\/noindex>, under udviklingen bruger Clang som deres prim\u00e6re compilator, og opbygninger baseret p\u00e5 den er mere kvalitets-testede. Brug af Clang til s\u00e5danne pakker vil undg\u00e5 problemer, der opst\u00e5r ved opbygning i GCC, samt behovet for at afstemme rettelser af disse fejl med hovedprojektet. Opbygning med GCC har en positiv indflydelse p\u00e5 opretholdelse af kodeportabilitet udviklet med Clang, men skaber en st\u00f8rre byrde for vedligeholdelse og forsinker offentligg\u00f8relse af opdateringer (f.eks. Mozilla forbinder<\/a><\/noindex> bruge varem\u00e6rket Firefox ved anvendelse af tredjeparts patcher, hvorfor det er n\u00f8dvendigt f\u00f8rst at sikre inkluderingen af patcherne i det prim\u00e6re indhold og offentligg\u00f8re opdateringen f\u00f8rst efter at rettelserne er tilg\u00e6ngelige i upstream).<\/p>\n

Det bem\u00e6rkes, at det ville v\u00e6re logisk at bruge Clang til pakker, hvor denne compilator passer bedre og anvendes i hovedprojektet. For s\u00e5danne pakker ville det v\u00e6re muligt at reducere vedligeholdelsesbyrden, hvis pakkeopbygningen udf\u00f8res af repr\u00e6sentanter fra hovedprojektet. Hvis en repr\u00e6sentant fra f\u00e6llesskabet udf\u00f8rer pakkeopbygningen, b\u00f8r muligheden for at v\u00e6lge compilator gives til vedligeholderen. For pakker, hvis hovedprojekter ikke har pr\u00e6ference for en bestemt compilator anbefales det at bevare status quo (bygge med GCC som tidligere). Forslaget kommer fra Jeff Law fra Red Hat, som er en af vedligeholderne af GCC og Binutils.<\/p>\n
