With HAVE_GAS_WEAKDEF undef'd, we have a large number of objc failures with the following error: Executing on host: /mnt/gnu/gcc-3.3/objdir/gcc/xgcc -B/mnt/gnu/gcc-3.3/objdir/gc c/ /mnt/gnu/gcc-3.3/gcc/gcc/testsuite/objc/execute/exceptions/catchall-1.m -w -O0 -fgnu-runtime -fobjc-exceptions -I/mnt/gnu/gcc-3.3/gcc/gcc/testsuite/../../ libobjc -L/mnt/gnu/gcc-3.3/objdir/hppa2.0w-hp-hpux11.11/./libobjc/.libs -lobjc -lm -o /mnt/gnu/gcc-3.3/objdir/gcc/testsuite/catchall-1.x0 (timeout = 300) PASS: objc/execute/exceptions/catchall-1.m compilation, -O0 -fgnu-runtime Setting LD_LIBRARY_PATH to .::/mnt/gnu/gcc-3.3/objdir/gcc:/mnt/gnu/gcc-3.3/objdi r/gcc:/mnt/gnu/gcc-3.3/objdir/hppa2.0w-hp-hpux11.11/./libobjc/.libs:.::/mnt/gnu/ gcc-3.3/objdir/gcc:/mnt/gnu/gcc-3.3/objdir/gcc:/mnt/gnu/gcc-3.3/objdir/hppa2.0w- hp-hpux11.11/./libobjc/.libs /usr/lib/dld.sl: Unresolved symbol: pthread_attr_init (code) from /mnt/gnu/gcc- 3.3/objdir/hppa2.0w-hp-hpux11.11/./libobjc/.libs/libobjc.sl.1 FAIL: objc/execute/exceptions/catchall-1.m execution, -O0 -fgnu-runtime set_ld_library_path_env_vars: ld_library_path=.::/mnt/gnu/gcc-3.3/objdir/gcc:/mn t/gnu/gcc-3.3/objdir/gcc:/mnt/gnu/gcc-3.3/objdir/hppa2.0w-hp-hpux11.11/./libobjc /.libs This reference comes from thr-objc.o: thr-objc.o U pthread_attr_init The header defines pthread_attr_init as follows: static int pthread_attr_init( pthread_attr_t *attr) { return(__pthread_attr_init_system(attr)); } we have extern __typeof(pthread_attr_init) __gthrw_pthread_attr_init __asm ("" "pthread_ attr_init"); and in __gthread_objc_init_thread_system if (__gthrw_pthread_attr_init (&_objc_thread_attribs) == 0 && __gthrw_pthread_attr_setdetachstate (&_objc_thread_attribs, 0xde) == 0) return 0; but in the .s file, we have in __objc_init_thread_system a call to pthread_attr_init: .CALL ARGW0=GR bl pthread_attr_init,%r2 .IMPORT pthread_attr_init,CODE This shows that using __asm to create aliases to static inline function fails.
