Inginerii de la S o l l o b o r a au publicat un raport privind implementarea proiectului de asigurare a compil\u0103rii bibliotecii sistemului GNU C Library (glibc) folosind instrumentele LLVM (Clang, LLD, compiler-rt) \u00een loc de GCC. P\u00e2n\u0103 de cur\u00e2nd, Glibc a r\u0103mas unul dintre componentele semnificative ale distribu\u021biilor, suport\u00e2nd compilarea doar prin GCC. <\/p>\n

Dificult\u0103\u021bile adapt\u0103rii Glibc pentru compilarea cu LLVM sunt cauzate at\u00e2t de diferen\u021bele \u00een comportamentul GCC \u0219i Clang \u00een tratarea unor construc\u021bii (de exemplu, expresii cu simbolul $, func\u021bii \u00eenchise, etichete \u00een blocuri asm, tipuri long double \u0219i float128), c\u00e2t \u0219i de necesitatea \u00eenlocuirii runtime-ului libgcc cu compiler-rt. <\/p>\n

Pentru a asigura compilarea Glibc cu LLVM, au fost preg\u0103tite aproximativ 150 de patch-uri pentru mediul Gentoo \u0219i 160 pentru un mediu bazat pe ChromiumOS. \u00cen starea actual\u0103, compilarea \u00een ChromiumOS trece deja cu succes setul de teste, dar nu este \u00eenc\u0103 activat\u0103 din mod\u0103 implicit\u0103. Urm\u0103torul pas va fi transmiterea modific\u0103rilor preg\u0103tite \u00een cadrul principal al Glibc \u0219i LLVM, continuarea test\u0103rii \u0219i corectarea problemelor nea\u0219teptate. Unele dintre patch-uri au fost deja acceptate \u00een ramura Glibc 2.37.
