Hi, after http://gcc.gnu.org/ml/gcc-patches/2011-04/msg02139.html profiling uses TLS support where available. This breaks on SPARC/Solaris 8 and 9 (at least) because the associated libraries aren't linked in. Tested on SPARC/Solaris 8 and SPARC64/Solaris 9 (the Solaris 10 machine isn't in very good shape right now), OK for the mainline? 2011-05-22 Eric Botcazou * config/sol2.h (LIB_SPEC): Link TLS support for profiling. -- Eric Botcazou
