Gli ingegneri di Collabora hanno pubblicato un rapporto sulla realizzazione del progetto volto a garantire la compilazione della libreria standard GNU C Library (glibc) utilizzando gli strumenti LLVM (Clang, LLD, compiler-rt) al posto di GCC. Fino a poco tempo fa, Glibc rappresentava uno dei componenti significativi delle distribuzioni che supportavano la compilazione esclusivamente tramite GCC. <\/p>\n

Le difficolt\u00e0 di adattamento di Glibc per la compilazione tramite LLVM sono dovute sia alle differenze nel comportamento di GCC e Clang nel gestire alcune costruzioni (ad esempio, espressioni con il simbolo $, funzioni annidate, etichette in blocchi asm, tipi long double e float128), sia alla necessit\u00e0 di sostituire il runtime da libgcc a compiler-rt. <\/p>\n

Per garantire la compilazione di Glibc tramite LLVM sono stati preparati circa 150 patch per l'ambiente Gentoo e 160 per l'ambiente basato su ChromiumOS. Nella sua attuale forma, la compilazione su ChromiumOS ha gi\u00e0 superato con successo il set di test, ma non \u00e8 ancora abilitata per impostazione predefinita. Il prossimo passo sar\u00e0 trasferire le modifiche preparate nel ramo principale di Glibc e LLVM, continuare il testing e risolvere i problemi poco comuni che emergeranno. Alcuni dei patch sono gi\u00e0 stati accettati nel ramo Glibc 2.37.
