SORT_BY_INIT_PRIORITY
I was looking at the implementation of this script keyword today and
couldn't remember why we do what we do in get_init_priority, because
the comments explain how the init_priority is encoded but don't say
why it is necessary to extract the priority and sort on that. So
after figuring out why (again), I wrote some more comments.
Then I simplified get_init_priority a little, adding some sanity
checking on the strtoul result. This actually makes get_init_priority
support sorting by numerical suffix more generally, but I figure this
feature would be better as a new keyword (without the .ctors/.dtors
special case), so haven't documented the extension.
* ld.texi (SORT_BY_ALIGNMENT): Reword slightly.
(SORT_BY_INIT_PRIORITY): Elucidate.
* ldlang.c: Include limits.h.
(get_init_priority): Comment. Change param to a section,
return an int. Sanity check priority digits. Support sorting
more sections with trailing digits. Return -1 on error.
(compare_section): Adjust.
