In\u017cynierowie z firmy Collabora opublikowali raport dotycz\u0105cy realizacji projektu zapewnienia wsparcia dla budowy systemowej biblioteki GNU C Library (glibc) z wykorzystaniem narz\u0119dzi LLVM (Clang, LLD, compiler-rt) zamiast GCC. Do niedawna glibc pozostawa\u0142 jednym z kluczowych komponent\u00f3w dystrybucji, kt\u00f3re wspiera\u0142y budow\u0119 wy\u0142\u0105cznie za pomoc\u0105 GCC. <\/p>\n

Trudno\u015bci w adaptacji glibc do budowy z u\u017cyciem LLVM wynikaj\u0105 zar\u00f3wno z r\u00f3\u017cnic w zachowaniu GCC i Clang przy przetwarzaniu niekt\u00f3rych konstrukcji (na przyk\u0142ad wyra\u017ce\u0144 z symbolem $, zagnie\u017cd\u017conych funkcji, etykiet w blokach asm, typ\u00f3w long double i float128), jak i z konieczno\u015bci zast\u0105pienia runtime z libgcc na compiler-rt. <\/p>\n

Aby zapewni\u0107 budow\u0119 glibc z u\u017cyciem LLVM, przygotowano oko\u0142o 150 patchy dla \u015brodowiska Gentoo i 160 dla \u015brodowiska opartego na ChromiumOS. W bie\u017c\u0105cej postaci budowa w ChromiumOS ju\u017c pomy\u015blnie przechodzi zestaw test\u00f3w, ale nie jest jeszcze w\u0142\u0105czona domy\u015blnie. Kolejnym krokiem b\u0119dzie przekazanie przygotowanych zmian do g\u0142\u00f3wnego repozytorium glibc i LLVM, kontynuacja testowania i naprawa pojawiaj\u0105cych si\u0119 nietypowych problem\u00f3w. Niekt\u00f3re z patchy zosta\u0142y ju\u017c przyj\u0119te do ga\u0142\u0119zi glibc 2.37.
