When rtld runs the .fini section in a shared lib (C++), the code in
question from .../contrib/gdb/config/alpha/crtbegin.asm first calls
__do_globals_dtors_aux and then __do_frame_takedown. Unfortunately, the
value of gp after a jsr is undefined and in this case had changed from before
the call, probably as a result of calling code in some other shared library.
The normal calling convention for alpha is to re-initialize gp using
'ldgp gp,0(ra)' after a jsr instruction but in this case no such
re-initialization is done. This leads to a bogus value being read for the
address of __do_frame_takedown and a quick segfault.

value, it forces GCC to not optimize above this level. For intance, GCC
made with "WANT_FORCE_OPTIMIZATION_DOWNGRADE=1" is a good setting for the
Alpha platform when building ports.

All of the following are now valid:
.Rv -std f1
.Rv -std f1 f2
.Rv -std f1 f2 f3
.Rv -std
The last form is useful where the standard return behavior is applicable
to all of the functions described in this particular manpage. Look, for
example, at the stat(2), setresuid(2), and utimes(2) manpages.
The form with >1 functions is useful in a mixed environment. See the
fhopen(2) manpage for an example.

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
I am not sure who thought that making FreeBSD depend on ISC's libbsd
was a sensible thing to do.
Thus I have ripped out the define of gettimeofday() and isc__gettimeofday()
out of this file, since we:
1) Don't use nor build libbsd (FreeBSD might give a hint in its name as to
why)
2) Our gettimeofday() is the same in semantics as prototyped in ISC's
libbsd.
This was something which could have been fixed before it was released if
we had at least some insight into the development process. But my praying
fell on deaf ears it seems.
Of course, if I am wrong I welcome the corrections to my thinking, gladly
even.
