Several changes to dict_hash from Adacore's local version were inadvertantly
left out of the last change to that function. These changes conservatively
cause dict_hash to revert to msymbol_hash_iw in more cases where the symbol
being hashed is known not to be Ada-encoded. This avoids a few cases where
the function hashes large groups of names with similar prefixes to the same
value.
Changelog:
gdb/
* dictionary.c (dict_hash): Revert to msymbol_hash_iw in
more cases.
This is a clean-up of some of our symbol-lookup machinery to pull some
kludgy Ada-specific definitions out of psymtab.c. In place of
map_ada_symtabs and ada_lookup_partial_symbol, we have a method
map_matching_symbols, which searches through all symbol tables and
partial symbol tables looking for a symbol that matches according to
a matching function that is passed as a parameter. This requires some
care, because partial symbol tables speed up searches by binary search,
while full symbol tables use hashing. To call map_matching_symbols, therefore,
you may need to supply both a matching function that is compatible with the
dictionary hash function and an ordering relation that is compatible with
strcmp_iw, which is used to order partial symbol tables.
Having added this general routine to psymtab.c, we use it in ada-lang.c
to rework add_non_local_symbols (now renamed add_nonlocal_symbols).
Changelog:
gdb/
* ada-lang.c (full_match): Declare.
(ada_match_name): Rename to match_name (we should avoid prefixing static
symbols with "ada_").
(match_name): New name for ada_match_name.

* symfile.h: Replace map_ada_symtabs definition with map_matching_symbols.
This patch allows Ada to speed up symbol lookup by using the facilities
in dictionary.[ch] for hashed lookups. First, we generalize dictionary
search to allow clients to specify any matching function compatible with
the hashing function. Next, we modify the hashing algorithm so that symbols
that wild-match a name hash to the same value. Finally, we modify Ada
symbol lookup to use these facilities.
Because this patch touches on a hashing algorithm used by other
languages, I took the precaution of doing a speed test on a list of
about 12000 identifiers (repeatedly inserting all of them into a table
and then doing a lookup on a million names at random, thus testing the
speed of the hashing algorithm and how well it distributed names).
There was actually a slight speedup, probably as a result of open-
coding some of the tests in msymbol_hash_iw. By design, the revised
hashing algorithm produces the same results as the original on most
"normal" C identifiers.
We considered augmenting the dictionary interface still further by allowing
different hashing algorithms for different dictionaries, based on the
(supposed) language of the symbols in that dictionary. While this produced
better isolation of the changes to Ada programs, the additional flexibility
also complicated the dictionary interface. I'd prefer to keep things
simple for now.
Tested w/o regressions on Linux i686.

When one of the parameter values in a subprogram calls is an array
whose value does not come from inferior memory, the debugger first
copies the array value in inferior memory. Up to now, the memory
used to hold that copy was taken from the stack (just below the SP),
but this is causing problems on SPARC v9.
So the immediate fix is to follow what C does with arrays and strings,
which is allocate memory on the heap.
gdb/ChangeLog:
* ada-lang.c: #include "value.h".
(ensure_lval): Delete advance declaration. Remove gdbarch and sp
arguments. Implement using value_allocate_space_in_inferior
instead of allocating memory from the stack.

This patch adds handling of the case when a fat pointer has the
P_ARRAY and/or P_BOUNDS fields defined as a stub. In that case,
this stub needs to be resolved.
There are two issues:
. First, making sure that the resolution takes place itself.
That's the change to ada_check_typedef.
. Make sure that the type returned after resolution is not itself
a typedef. This is the change to ada_check_typedef.
gdb/ChangeLog (Jerome Guitton, Joel Brobecker):
* ada-lang.c (desc_bounds): Add handling of the case where
the P_BOUNDS field is a pointer to a stub.

After thread support over core files was added for GNU/Linux was added,
we started noticing the following type of crash when trying to perform
task switches (this is a bit accademic, since task switching is not
supported when debugging core files - this is what our testcase was
verifying).
(please check out the comment inside ada-tasks.c:task_command for
more details on this topic)
The reason for the crash comes from the fact that the GNU/Linux thread
layer now gets pushed on the target stack, causing the associated
to_get_ada_task_ptid target method to be activated. This routine
makes the assumption that, for all threads, the private area is not
NULL. This is incorrect in the case of core files, as the core layer
creates some threads with no private data.
But, taking a step back, we don't need to try to compute the task ptid,
as we'll never be using it anyways (we only use it for task switching).
So the fix is to avoid the ptid computation altogether when debugging
a core file.
gdb/ChangeLog:
* ada-tasks.c (read_atcb): Do not compute the task ptid when
debugging a core file.
* dwarf2read.c (die_needs_namespace) <DW_TAG_variable>: Add also
DW_TAG_constant.
gdb/testsuite/
* gdb.fortran/module.exp (fully qualified name of DW_TAG_constant):
New test.
* gdb.fortran/module.f90 (mod1) <var_const>: New constant.
The testcase was failing on various 64bit platforms, because the
debugging info said that the target type for a const type is a
4-byte reference. In the asm file, I used a .long directive, but
the size of .long is of course dependent on the platform. This
replaces this .long by a .4byte directive.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-const.S: Use .4byte to reference the target
type of our const type.
This patch adds a new --enable-gdbserver=yes/no/auto command-line switch
in gdb/configure. The primary purpose is to allow a user to disable the
build & install of gdbserver when not desired. It also allows the user
to request gdbserver in which case the configure script will abort if
automatic building of gdbserver is not supported for that configuration.
The default keeps things as is: We automatically build gdbserver if
building for a native configuration and if gdbserver is supported for
that configuration.
gdb/ChangeLog:
* configure.ac: Add support for --enable-gdbserver.
* configure: Regenerate.
At AdaCore, this is mostly intended for ia64-linux, where we currently
do not want to distribute gdbserver. This will be useful in the context
of I417-033, where we are now using "make install" to determine what
needs to be packaged inside the GNAT Pro package.

This patch adjusts the NEWS entry for the LynxOS gdbserver to include

gdb/ChangeLog:

This patch adds support for x86 LynxOS (tested on LynxOS 5.0).

gdb/ChangeLog:
* NEWS: Announce GDBserver support for version 5.x of ppc-lynxos.
Some of the PTRACE_ macros/values were removed in LynxOS 5.x.
Since we have not use them so far, the chances that we will use them
one day are very small. So I decided to delete them.
gdb/gdbserver/ChangeLog:
* lynx-low.c (ptrace_request_to_str): Remove handling for
request values that have been removed in LynxOS 5.x.
This is one of the changes needed in order to build gdbserver on
LynxOS 5.x.
Really interesting: On LynxOS 4.x, there is a #warning when sys/ptrace.h
is used (explaining that ptrace.h will be used instead), whereas this
file was removed from LynxOS 5.x. The contents of sys/ptrace.h on 4.x
(or at least the meat of it):
#if defined(__GNUC__) || defined(__GNUG__)
#if !defined(__NO_INCLUDE_WARN__)
#warning Using <ptrace.h> instead of <sys/ptrace.h>
#endif /* defined(__NO_INCLUDE_WARN__) */
#endif /* defined(__GNUC__) || defined(__GNUG__) */
#include <ptrace.h>
The fix I went for, for now, is to just include <sys/ptrace.h>
unconditionally. I could have done some configury, but we already
have to build with -D__NO_INCLUDE_WARN__ to avoid the warnings
anyway, and that's unvoidable, due to system includes themselves
including the "wrong" header file.
Since <sys/ptrace.h> seems to be the choice that was made for LynxOS,
and since it works to include it on LynxOS 4.x, I think that's the simplest
solution.
