[testsuite/Ada] stop using project files when building test programs
The current approach when building Ada programs for testing is
based on the use of a project file (testsuite/gdb.ada/gnat_ada.gpr).
To do that, we pass a number of additional arguments to target_compile,
one of them being the project file (via "-P/path/to/gnat_ada.gpr").
This used to work well-enough, but AdaCore is currently working towards
removing project-file support from gnatmake (the prefered tool for
using project files is gprbuild). So, we need to either switch
the compilation to gprbuild, or stop using project files.
First, using gprbuild is not always what users will be using to
build their applications. So having the option of using gnatmake
provides more flexibility towards exactly reproducing past bugs.
If we ever need a testcase that requires the use of gprbuild, then
I believe support for a new target needs to be added to dejagnu's
target_compile.
Also, the only real reason behind using a project file in the first
place is that we wanted to make it easy to specify the directory
where all compilation artifacts get stored. This is a consequence
of the organization choice we made for gdb.ada to keep each testcase
well organized. It is very easy to achieve that goal without using
project files.
This is therefore what this patch does: It change gdb_compile_ada
to build any program using gnatmake without using a project file
(by temporarily changing the current working directory).
There is a small (beneficial) side-effect; in the situation where
GDB is built in-tree, gnatmake is called as...
% gnatmake [...] unit.adb
... which means that the debugging info in unit.o will say contain
a filename whose name is 'unit.adb', rather than '/path/to/unit.adb'.
This also better matches what users might typically do. But the side-
effect is that the unit name in the GDB output is not always a full
path. This patch tweaks a couple of testcases to make the path part
optional.

[lynxos] gdbserver hangs when killing inferior from GDB
With any program under GDBserver control on LynxOS, killing
the program from the debugger (using the "kill" command) causes
GDBserver to properly kill the inferior but GDBserver then hangs.
This change of behavior occured after the following change was
applied:
commit
f0ea042932e6922c90df3fd0001497d287b97677
Date: Mon Nov 30 16:05:27 2015 +0000
Subject: gdbserver: don't exit until GDB disconnects
One of the changes introduced by the commit above is that
process_serial_event no longer calls exit after handling
the vKill packet. Instead, what happens is that we wait
until captured_main finds that we no longer have any inferior
to debug, at which point it throws_quit. This (normal) exception
is then expected to propagate all the way to the exception handle
in function "main", which calls exit.
However, before the exception gets propagated, the cleanups
are first executed, and one of the cleanups in question is
detach_or_kill_for_exit_cleanup, which was put in place by
captured_main. detach_or_kill_for_exit_cleanup is basically
a wrapper around detach_or_kill_for_exit, which iterates
over all inferiors, and kills them all.
In our case, we have only one inferior, which we have already
killed during the handling for the "vKill" packet. Unfortunately,
we did not properly clean our internal data for that inferior up,
and so detach_or_kill_for_exit thinks that we still have one inferior,
and therefore tries to kill it. This results in lynx_kill being
called, doing the following:
lynx_ptrace (PTRACE_KILL, ptid, 0, 0, 0);
lynx_wait (ptid, &status, 0);
the_target->mourn (process);
The hang is caused by the call to lynx_wait, which waits for
an event from a process which does not exist...
This patch fixes the issue by enhancing lynx_mourn to clean
the threads and process list up.
gdb/gdbserver/ChangeLog:
* lynx-low.c (lynx_delete_thread_callback): New function.
(lynx_mourn): Properly delete our process and all of its

[win32] cannot automatically find executable file [...] warning at GDB startup
The following change...
commit
43499ea30db2a866412c86952c7e1d7b158d806f
Date: Tue Nov 17 15:17:44 2015 +0000

warning at startup:
% gdb

Use "file" or "dll" command to load executable/libraries directly.
GNU gdb (GDB) 7.10.50.
20151218-cvs (with AdaCore local changes)
[...]
(gdb)
The warning comes from _initialize_loadable which tries to dynamically
load some symbols from kernel32.dll and psapi.dll, and in particular:
hm = LoadLibrary ("psapi.dll");
if (hm)
{
GPA (hm, EnumProcessModules);
GPA (hm, GetModuleInformation);
GPA (hm, GetModuleFileNameEx);
}
The problem is that the new GPA macro assumes that the name of
the variable we use to point to the function, and the name of
its associated symbol are the same. This is mostly the case,
except for GetModuleFileNameEx, where the name is provided by
the GetModuleFileNameEx_name macro (defined differently depending
on whether we are on cygwin or not). As a result, the dynamic
resolution for GetModuleFileNameEx returns NULL, and we trip
the following check which leads to the warning:
if (!EnumProcessModules || !GetModuleInformation || !GetModuleFileNameEx)
{
[...]
warning(_("[...]"));
}
This patch fixes the problem by calling GetProcAddress directly,
rather than through the GPA macro, but in a way which hopefully
avoids the C++ compilation warning that the previous patch was
trying to get rid of.

Remove dead code in testsuite
This patch removes cases from the testsuite that are not posssibly used. The
messages "Catch of * not yet implemented" were removed here:
https://www.sourceware.org/ml/gdb-patches/2004-01/msg00679.html
I changed the regexp at the same time to match the string more closely.
gdb/testsuite/ChangeLog:
* gdb.base/break.exp: Remove dead code.
* gdb.base/sepdebug.exp: Likewise.

Remove HP-UX references fom testsuite
This patch removes all special cases for HP-UX, for which support has
been removed earlier, that I found in the testsuite. Note that the hppa
architecture != HP-UX, since other OSes can run on hppa, so I tried to
leave everything that is not HP-UX specific.
Two complete tests were completely HP-UX specific, so I removed them.
I ran the testsuite on Linux x86-64, native and native-gdbserver, and
noticed no regressions.

Remove references to HP CC/aCC compiler from testsuite
The HP CC/aCC compiler is exclusive to HP-UX, for which support has been
explicitly removed. Therefore, It does not make sense to keep tests
for these compilers' quirks.
