(diff113)
* include/gc.h (GC_has_static_roots_func): New typedef (user filter
callback).
* include/gc.h (GC_register_has_static_roots_callback): Use
GC_has_static_roots_func type.
* dyn_load.c (GC_has_static_roots,
GC_register_has_static_roots_callback): Ditto.
* dyn_load.c (GC_has_static_roots,
GC_register_has_static_roots_callback): Define on all platforms.
* dyn_load.c (GC_register_dynlib_callback,
GC_register_dynamic_libraries, GC_init_dyld): Replace K&R-style
functions definition with the ANSI C one.
* dyn_load.c (GC_register_dynlib_callback): Use new local variable
"callback" (initialized from GC_has_static_roots) to minimize data
races.
* dyn_load.c (GC_register_dynamic_libraries_dl_iterate_phdr,
GC_cond_add_roots): Define as STATIC.
* mark_rts.c (GC_remove_roots_inner): Ditto.
* dyn_load.c (GC_dyld_image_add): Don't call GC_add_roots() for
sections smaller than pointer size (just to avoid acquiring the
lock unnecessarily).
* dyn_load.c (GC_dyld_name_for_hdr): Define unconditionally (not
only for DARWIN_DEBUG).
* dyn_load.c (GC_dyld_image_add): Replace GC_add_roots() call with
LOCK + GC_add_roots_inner() + UNLOCK.
* dyn_load.c (GC_dyld_image_add): Call GC_has_static_roots() user
callback (if set) holding the lock; if it returns 0 then don't call
GC_add_roots_inner() for that region.
* dyn_load.c (GC_register_has_static_roots_callback): Put
"callback" value to GC_has_static_roots on all platforms.
* dyn_load.c (GC_has_static_roots): Update the comments.
* include/gc.h (GC_exclude_static_roots, GC_add_roots,
GC_remove_roots, GC_register_has_static_roots_callback): Ditto.
* include/private/gc_priv.h (struct roots): Ditto.
* include/private/gc_priv.h (GC_remove_roots_inner): Move prototype
to mark_rts.c and declare it as STATIC.
* include/private/gc_priv.h (GC_exclude_static_roots_inner): New
prototype.
* dyn_load.c (GC_register_dynamic_libraries_dl_iterate_phdr): Use
GC_exclude_static_roots_inner() instead of GC_exclude_static_roots.
* misc.c (GC_init_inner): Ditto.
* mark_rts.c (GC_exclude_static_roots_inner): New function (move
all the code from GC_exclude_static_roots(); add the comment.
* mark_rts.c (GC_add_roots_inner, GC_exclude_static_roots_inner):
add alignment assertion for the lower bound; add assertion for the
lower bound to be less than the upper one.
* mark_rts.c (GC_add_roots_inner, GC_exclude_static_roots): Adjust
the upper bound (round down to be of a pointer-aligned value);
return in case of an empty range.
* mark_rts.c (GC_exclude_static_roots): Acquire the lock and call
GC_exclude_static_roots_inner().
* mark_rts.c (GC_remove_roots): Quickly check the bounds and return
in case of a do-nothing case (before acquiring the lock).
