Michael,
According to the remote protocol, the remote side only has to know the
`general' and `continue' threads, there is no notion of `current' thread.
In the current implementation of gdbserver, there is no current thread, and it
works because the stub code always gets info from the same thread
(`inferior_pid'). In a multi-threaded context it is not possible without being
informed that the `general' thread has changed.
IMHO it is a good thing not to have to record the current thread in the remote
side and let the host side (gdb) decide which thread will be inspected and
which thread will continue, it will otherwise be a useless limitation of the
protocol. This way it could be possible to inspect one thread without changing
the current thread in gdb ...
Best regards.

FYI,
I consider it legitimate to use:
struct section_table;
extern struct section_addr_info
*build_section_addr_info_from_section_table (const? struct section_table
*start, const const? section_table *end);
(An asside, this is why I also suggest people avoid ``typedef struct''
:-).

I'll add that to my list of things to fix :-)

FYI, (and totally off the topic ...)
gdbarch is going to be broken into gdbarch.[hc] and gdbarch-utils.[hc].
target.[hc] is going to suffer a similar fate. Anything in target.[hc]
not directly relevant to the target vector is going to end up being
given the boot (to another file). Why? Any plan
multi-arching/multi-targeting GDB becomes just that bit more feasible if
the target vector is purged of all its current junk.
Anyway I'd rather target.[hc] didn't accumulate any more fluff.

I'd suggest having the definitions in the header file that best
corresponds to the .c file that contains the functions implementation.
My guess is that symtab.h/symtab.c might be the best candidates since
symtab.h defines the struct that the function is building/freeing.
However one of the other files would proably be equally suitable.

Ah, I'd not thought of it that way. Yes, very good point. While I can
try to insist that GDB / BFD are kept consistent, I can't impose that
requirement on the real world.
Your change is approved.
I'll see about clarifying the spec for gdbarch_init_ftype so that it
makes it clear that not recognizing the architecture is common and
should be handled cleanly.
As a second issue, there should be a test that checks that BFD/GDB are
in sync with regard to architecture changes. Something like a test that
first queries GDB for all supported architectures and then feeds each
back to GDB.. Anyone interested in learning how to write tests? :-)

As Eli notes, the average user doesn't know if a warning during an
unpack is legetimate or not. Having things unpack without warnings both
improves the out-of-box experience and reduces the number of apparently
silly (but actually legetimate) e-mail questions. Having the build
issue GCC warnings for things that won't/can't be fixed fixed is equally
confusing.
By way of an olive branch ;-) Is there anything that the nightly
snapshots (short term) and/or testsuite (medium/long term) can do to
ensure that the relevant djgpp files are always up-to-date?
As a suggestion from left field, I've wondered if gdb.base/selftest.exp
should be moved to gdb.wb/selftest.exp (wb == white box) so that people
can freely add additional white box tests to GDB. Checking consistency
between config/djgpp/<that-file> and the GDB sources could be part of
that testsuite.
enjoy,
Andrew

As far as I know, the dwarf2 and elf information are both ment to be
self contained. There shouldn't be any need to refer to some arbitrary
bfd table to determine what is going on. If the info says that an
address is 16 bits for a given section then it sounds like GDB should
just believe it.
As JimK suggested:

Rather than diging values out of archures I think the possibility of:
cu_header.address_size < elf-header.address_size
should be documented as being just as legetimate (sarcasm :-) as:
cu_header.address_size > elf-header.address_size
and the check either replaced or removed.

Thanks!
Whenever there is a finished version of the manual that you don't really
expect to change before the release, I'd like a copy, or just a pointer.
We are out of stock, and it would be good to put this into print ASAP.

I hasten to point out that it's not *my* trick. :) That's just the
way the watchpoint code works.
Eli's test of the value's type is incorrect if the watch expression
contains a structure comparison, like (foo == bar) || (something
else), where foo and bar are structures. In that case, there will be
a value of type "struct", not at the end of the value list, but which
should be watched in its entirety.
To say that "nothing in GDB's code suggests that this assumption will
hold" is too passive. We should instead say, "Nothing in GDB's code
suggests that it would be difficult to make this assumption hold;
therefore, since it would be useful if it did hold, we will extend the
description of struct value with the requirement that non-lazy values
should contain only the portions of the objects actually used."

Sorry, you are right.
I think this patch is a good idea, but I have one minor suggestion.
Instead of these two lines:
! size = (len > 4) ? 4 : len;
! size = size_try_array[size - 1][align];
I would suggest to write this:
size = size_try_array[len > 4 ? 3 : len - 1][align];
The reason is that IMHO we should avoid making a variable (`size')
serve two puproses at the same time.

Thanks!
It seems apology is in order: my previous message implied that I
posted that patch some time ago, while in reality I simply forgot to
post it. So there was nothing wrong with Elena not taking care of it.
Sorry!

Can you post the error mesage(s) you get from "make info"? perhaps
they are descriptive enough to identify the offending line(s).

How about if the 'sThread' request were to be suffixed with

Only that it conflicts with the tracepoint messages,
which all begin with qT (see tracepoint.c).

I'm pretty sure I tested with a "make info" in the objdir
the last time I checked in, but I'm not convenient to a
system I can retest this with; what error messages are you
getting?

Not to make you hunt for my previous reply to Eli Z,

This looks fine. Just an observation:
CONFIG_OBS is part of DEPFILES, which is part of COMMON_OBS, which is
part of OBS, which is part of INITFILES. It looks like all three usages
of CONFIG_INITS in configure.in can be removed. Maybe you can just
remove CONFIG_INITS altogether in configure.in and Makefile.in. Since
OBS file list is already looked at by init.c rule, it really makes no
sense to maintain a CONFIG_INITS file list.
