This avoids duplicate tests for functions between common m4, arches,
and any other sources that would trigger func tests.
Also manually delete known duplicate function tests between the m4,
bfin, and v850 ports.
|
|
These appear to have been blindly copied from the v850 port many years
ago as the code has never been used. Just delete it all and be done.

Hoist the Blackfin implementation up to the common one.

The printf fix uses our PRIxTA for our sim address type.
Then cast away the const (since the underlying code safely treats it
as such) even if it's ugly.
Finally touch up the argv iterator pointer to match the new func arg.
With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call
to get the default common behavior where -Werror is enabled.

The printf fix is obvious enough, but the hash one is a real bug:
cr16/interp.c: In function 'sim_open':
cr16/interp.c:560:17: error: 'h' may be used uninitialized in this function [-Werror=maybe-uninitialized]
560 | h = h->next;
| ~~^~~~~~~~~
It happens to not cause a problem currently because the first entry in
the generated table that this loop operates matches a codepath where h
is initialized. Then when later entries don't match, the previous value
is pointing at the end of a valid hash table already, and the rest of
the code does nothing.
With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call
to get the default common behavior where -Werror is enabled.

The .gdb_index was designed such that all data would be aligned.
Unfortunately, we neglected to require this alignment in the objcopy
instructions in the manual. As a result, in many cases, a .gdb_index
in the wild will not be properly aligned by mmap. This yields
undefined behavior, which is PR gdb/23743.
This patch fixes the bug by always assuming that the mapping is
unaligned, and using extract_unsigned_integer when needed. A new
helper class is introduced to make this less painful.

quick_symbol_functions::map_matching_symbols is only used by the Ada
code. Currently, it both expands certain psymtabs and then walks over
the full symtabs -- including any already-expanded ones -- calling a
callback.
It appears to work lazily as well, in that if the callback returns
false, iteration stops. However, only the psymtab implementation does
this; the DWARF index implementations are not lazy. It turns out,
though, that the only callback that is ever passed here never returns
false.
This patch simplifies this method by removing the callback. The
method is also renamed. In the new scheme, the caller is responsible
for walking the full symtabs, which removes some redundancy as well.

Currently, expand_symtabs_matching only accepts a search_domain
parameter. However, lookup_symbol uses a domain_enum instead, and the
two, confusingly, do quite different things -- one cannot emulate the
other. So, this patch adds a domain_enum parameter to
expand_symtabs_matching, with UNDEF_DOMAIN used as a wildcard.
This is another step toward replacing lookup_symbol with
expand_symtabs_matching.

This changes expand_symtabs_exp_notify_ftype to return bool, and

The Rust expression parser was written to construct its own AST, then
lower this to GDB expressions. I did this primarily because the old
expressions were difficult to work with; after rewriting those, I
realized I could remove the AST from the Rust parser.
After looking at this, I realized it might be simpler to rewrite the
parser. This patch reimplements it as a recursive-descent parser. I
kept a fair amount of the existing code -- the lexer is pulled in
nearly unchanged.
There are several benefits to this approach:
* The parser is shorter now (from 2882 LOC to 2351).
* The parser is just ordinary C++ code that can be debugged in the
usual way.
* Memory management in the parser is now straightforward, as
parsing methods simply return a unique pointer or vector.
This required a couple of minor changes to the test suite, as some
errors have changed.
While this passes the tests, it's possible there are lurking bugs,
particularly around error handling.

By default, when using the -g switch, avr-gcc generates stabs debug
information. I think it would make more sense to test GDB against DWARF
information, because stabs is obsolete by now, and nobody work on it.
So change the simavr board to pass -gdwarf-4 as the debug flag.
The downside is that users are probably more likely to use just -g, so
we don't test GDB the same way as users are likely to use it. But in
this case, if somebody comes and asks for help with GDB for AVR, I
suggest we encourage them to use -gdwarf-4.
I can't give stats about how that changes test results, because the
testsuite is too broken. There is an internal error that happens quite
frequently that needs to be investigated:
/home/simark/src/wt/avr/gdb/trad-frame.h:143: internal-error: LONGEST trad_frame_saved_reg::addr() const: Assertion `m_kind == trad_frame_saved_reg_kind::ADDR' failed.
I sent a question on the gcc mailing list, asking why stabs is the
default:

Even if the DWARF information contains a bfloat16 base type (__bf16), a
variable of such type will still be printed using the IEEE half float format,
which is wrong.
This patch teaches GDB how to pick the bfloat16 format for __bf16 types in
DWARF (based on the base type name) and uses IEEE half float for all the other
16-bit float formats.

GDB was crashing in "bt full" for a large Ada program. I tracked this
down to a combination of bugs.
The first bug, fixed here, is that print_variable_and_value calls
common_val_print. Normally only the value-printing implementation
should call this; from the top level, common_val_print_checked is
preferred, because it correctly handles values that are wholly
optimized out.
I wasn't able to write a test case for this.

common_val_print_checked.

I noticed that var_value_operation takes a block and a symbol, and
most callers destructure a block_symbol to pass in. It seems better
for this class to simply hold a block_symbol instead.
Tested on x86-64 Fedora 32.

This adds a new command to change GDB to behave as though "-quiet"
were always given. This new command can be added to the gdbearlyinit
file to affect future GDB sessions.
gdb/ChangeLog:
* NEWS: Add entry.
* main.c (captured_main_1): Call check_quiet_mode.
* top.c (startup_quiet): New global.
(check_quiet_mode): New function.
(show_startup_quiet): New function.
(init_main): Register new command.
* top.h (check_quiet_mode): Declare.
gdb/doc/ChangeLog:
* gdb.texinfo (Mode Options): Mention "set startup-quietly".
gdb/testsuite/ChangeLog:
* gdb.base/startup-file.exp: Add more tests.

Adds the ability to process commands at a new phase during GDB's
startup. This phase is earlier than the current initialisation file
processing, before GDB has produced any output.
The number of commands that can be processed at this early stage will
be limited, and it is expected that the only commands that would be
processed at this stage will relate to some of the fundamentals of how
GDB starts up.
Currently the only commands that it makes sense to add to this early
initialization file are those like 'set style version ....' as the
version string is displayed during startup before the standard
initialization files are parsed. As such this commit fully resolved
bug cli/25956.
This commit adds a mechanism to execute these early initialization
files from a users HOME directory, as well as some corresponding
command line flags for GDB.
The early initialization files that GDB will currently check for are
~/.config/gdb/gdbearlyinit (on Linux like systems) or ~/.gdbearlyinit
if the former is not found.
The output of 'gdb --help' has been extended to include a list of the
early initialization files being processed.
