* sysdeps/mach/hurd/i386/init-first.c (__libc_argc, __libc_argv):
New variables.
(init1): Initialize them.
* hurd/hurdinit.c (_hurd_setproc): Now that happens to be
available, pass __libc_argv in call to __proc_set_arg_locations.
* gmon/gmon.c (write_hist): Call __profile_frequency instead of
hertz.
(hertz): Delete function.
* gmon/Makefile (routines): Add `prof-freq'.
* sysdeps/generic/prof-freq.c: New file.
* sysdeps/mach/hurd/prof-freq.c: New (stubby) file.
* sysdeps/mach/hurd/profil.c (profile_tick): New variable.
(update_waiter): Store frequency in profile_tick.
(__profile_frequency): New function.
* sysdeps/mach/hurd/sendto.c (sendto): Use prototype definition
syntax.
* Rules (generated): Restore reference to $(generated).
* mach/Machrules (mig.uh, mig.__h): Don't include $(user-MIGFLAGS)
here.
* malloc/free.c (free): __lib_malloc_lock -> __libc_malloc_lock.
* malloc/free.c: Provide extern decl of __libc_malloc_lock.
* malloc/realloc.c: Likewise.
* malloc/malloc-find.c: Likewise.
* malloc/malloc-size.c: Likewise.
* malloc/malloc-walk.c: Likewise.
* malloc/memalign.c: Likewise.
* mach/Machrules (mig.uh, mig.__h): Include $(user-MIGFLAGS) and
Diffstat (limited to 'sysdeps/mach/hurd/profil.c')
