Gli ingegneri di Collabora hanno pubblicato un rapporto sull'implementazione di un progetto per garantire la compilazione della libreria di sistema GNU C Library (glibc) utilizzando gli strumenti LLVM (Clang, LLD, compiler-rt) invece di GCC. Fino a poco tempo fa, Glibc era uno dei componenti significativi delle distribuzioni che supportavano la compilazione esclusivamente con GCC. <\/p>\n

Le difficolt\u00e0 nell'adattare Glibc per la compilazione con LLVM sono causate sia dalle differenze nel comportamento di GCC e Clang nell'elaborazione di alcune costruzioni (ad esempio, espressioni con il simbolo $, funzioni nidificate, etichette nei blocchi asm, tipi long double e float128), sia dalla necessit\u00e0 di sostituire il runtime da libgcc a compiler-rt. <\/p>\n

Per garantire la compilazione di Glibc con LLVM, sono stati preparati circa 150 patch per l'ambiente Gentoo e 160 per l'ambiente basato su ChromiumOS. Nella forma attuale, la compilazione in ChromiumOS supera gi\u00e0 con successo un set di test, ma non \u00e8 ancora inclusa per impostazione predefinita. Il prossimo passo sar\u00e0 trasmettere le modifiche preparate nel principale insieme di Glibc e LLVM, continuare il testing e risolvere i problemi non comuni che emergono. Alcune delle patch sono gi\u00e0 state accettate nel ramo Glibc 2.37.
