I wanted to find the docs for "catch load" the other day, and I found
out that this isn't in the index. It seems to me that each command
ought to be in the index for quick reference like this, so this patch
adds an @kindex (chosen because it seems to be what the rest of the
manual does) for each "catch" subcommand.

* gdb.texinfo (Set Catchpoints): Add @kindex for each command
documented here.
I happened to notice that the gdbserver program doesn't appear in the
top-level "dir" file. This adds an entry for it to the gdb manual.

* gdb.base/sigall.exp (test_one_sig): gdb identifies SIGLOST as a
SIGPWR in sparc64.
* gdb.base/sigall.c (main): In some targets SIGLOST and SIGPWR
have the same signal number. Handle this situation.
Consider the following code:
type Ptr is access all Integer;
IP : Ptr := new Integer'(123);
IP is the Ada exception of a pointer to an integer. To dereference
the pointer and get its value, the user uses the reserved word "all"
as follow:
(gdb) p ip.all
$1 = 123
Ada being a case-insensitive language, the casing should not matter.
Unfortunately, for the reserved word "all", things don't work. For
instance:
(gdb) p ip.ALL
Type integer is not a structure or union type
This patch fixes the problem.
gdb/ChangeLog:
* ada-lex.l (find_dot_all): Use strncasecmp instead of strncmp.
gdb/testsuite/ChangeLog:
* gdb.ada/dot_all: New testcase.
With a program raising an exception, trying to debug that program
in GDB/MI mode can yield a crash:
% gdb -i=mi foo
(gdb)
-catch-exception -e "Program_Error"
^done,bkptno="2",bkpt={number="2",type="breakpoint",[...]
(gdb)
-exec-continue
^running
*running,thread-id="all"
(gdb)
=library-loaded,id=[...]
&"warning: failed to reevaluate internal exception condition for catchpoint 2: Error in expression, near `'.\n"
zsh: 22956 bus error (core dumped) gdb -q -i=mi foo
The problem is triggered by a problem in the compiler which causes
EXP in the following TRY_CATCH block to change unexpectedly when
parse_exp_1 throws an error :
| TRY_CATCH (e, RETURN_MASK_ERROR)
| {
| exp = parse_exp_1 (&s, bl->address,
| block_for_pc (bl->address), 0);
| }
In ada-lang.c:create_excep_cond_exprs, EXP is initialized to NULL,
and is expected to remain NULL if parse_exp_1 throws. Instead,
its value gets changed to something invalid. This later crashes
the debugger, when trying to evaluate the bogus expression.
This patch works around the issue by simply forcing EXP back to NULL
when an exception was thrown. A comment explaining why, and the sort
of timeline we're looking at for a fix, is also added.
gdb/ChangeLog:
* ada-lang.c (create_excep_cond_exprs): Force EXP to NULL

This patch extends a bit the news entry we added which documents
general support of the --language option, to add a small reference
to the associated entry which was also added to the "-list-features"
command output.
gdb/ChangeLog:
* NEWS: Mention "-list-features" in the entry documenting
the support for the "--language" option.
I don't know what I was thinking here to omit the save of r2.
Possibly I was looking at -msave-toc-indirect code at the time, where
r2 is saved in the function prologue.
* elf64-ppc.c (ppc_build_one_stub <ppc_stub_plt_branch_r2off>):
Don't omit saving of r2 for ELFv2. Don't addi 2,2,0.
(ppc_size_one_stub <ppc_stub_plt_branch_r2off>): Adjust to suit.
Now that the -info-gdb-mi-command is available, there is no need for
this entry. The entry and associated new commands were added recently
enough that no front-end out there should be depending on it yet.
gdb/ChangeLog:
* mi/mi-main.c (mi_cmd_list_features): Remove "ada-exceptions".
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Miscellaneous Commands): Remove the
documentation of the "ada-exceptions" entry.
With -mcmodel=medium we can't assume that a -R object doesn't use
toc-relative addressing if there's no toc. Lots of things are
accessed via r2, not just the toc/got section. Also, testing for
.opd is plain wrong for ELFv2.
* elf64-ppc.c (ppc64_elf_link_just_syms): Remove .got check.
Handle ELFv2.
... when trying to execute an undefined GDB/MI command. When trying
to execute a GDB/MI command which does not exist, the current error
result record looks like this:
-unsupported
^error,msg="Undefined MI command: unsupported"
The only indication that the command does not exist is the error
message. It would be a little fragile for a consumer to rely solely
on the contents of the error message in order to determine whether
a command exists or not.
This patch improves the situation by adding concept of error
code, starting with one well-defined error code ("undefined-command")
identifying errors due to a non-existant command. Here is the new
output:
-unsupported
^error,msg="Undefined MI command: unsupported",code="undefined-command"
This error code is only displayed when the corresponding error
condition is met. Otherwise, the error record remains unchanged.
For instance:
-symbol-list-lines foo.adb
^error,msg="-symbol-list-lines: Unknown source file name."
For frontends to be able to know whether they can rely on this
variable, a new entry "undefined-command-error-code" has been
added to the "-list-features" command. Another option would be
to always generate an error="..." variable (for the default case,
we could decide for instance that the error code is the empty string).
But it seems more efficient to provide that info in "-list-features"
and then only add the error code when meaningful.
gdb/ChangeLog:
(from Pedro Alves <palves@redhat.com>)
(from Joel Brobecker <brobecker@adacore.com>)
* exceptions.h (enum_errors) <UNDEFINED_COMMAND_ERROR>: New enum.
* mi/mi-parse.c (mi_parse): Throw UNDEFINED_COMMAND_ERROR instead
of a regular error when the GDB/MI command does not exist.
* mi/mi-main.c (mi_cmd_list_features): Add
"undefined-command-error-code".
(mi_print_exception): Print an "undefined-command"
error code if EXCEPTION.ERROR is UNDEFINED_COMMAND_ERROR.
* NEWS: Add entry documenting the new "code" variable in
"^error" result records.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Result Records): Fix the syntax of the
"^error" result record concerning the error message. Document
the error code that may also be part of that result record.
(GDB/MI Miscellaneous Commands): Document the
"undefined-command-error-code" element in the output of
the "-list-features" GDB/MI command.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-undefined-cmd.exp: New testcase.
This patch adds a new GDB/MI command meant for graphical frontends
trying to determine whether a given GDB/MI command exists or not.
Examples:
-info-gdb-mi-command unsupported-command
^done,command={exists="false"}
(gdb)
-info-gdb-mi-command symbol-list-lines
^done,command={exists="true"}
(gdb)
At the moment, this is the only piece of information that this
command returns.
Eventually, and if needed, we can extend it to provide
command-specific pieces of information, such as updates to
the command's syntax since inception. This could become,
for instance:
-info-gdb-mi-command symbol-list-lines
^done,command={exists="true",features=[]}
(gdb)
-info-gdb-mi-command catch-assert
^done,command={exists="true",features=["conditions"]}
In the first case, it would mean that no extra features,
while in the second, it announces that the -catch-assert
command in this version of the debugger supports a feature
called "condition" - exact semantics to be documented with
combined with the rest of the queried command's documentation.
But for now, we start small, and only worry about existance.
And to bootstrap the process, I have added an entry in the
output of the -list-features command as well ("info-gdb-mi-command"),
allowing the graphical frontends to go through the following process:
1. Send -list-features, collect info from there as before;
2. Check if the output contains "info-gdb-mi-command".
If it does, then support for various commands can be
queried though -info-gdb-mi-command. Newer commands
will be expected to always be checked via this new
-info-gdb-mi-command.
gdb/ChangeLog:
* mi/mi-cmds.h (mi_cmd_info_gdb_mi_command): Declare.
* mi/mi-cmd-info.c (mi_cmd_info_gdb_mi_command): New function.

* mi/mi-main.c (mi_cmd_list_features): Add "info-gdb-mi-command"

* NEWS: Add entry for new -info-gdb-mi-command.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Miscellaneous Commands): Document
the new -info-gdb-mi-command GDB/MI command. Document

Remote servers may cut the connection abruptly since they are not

This patch addresses any issues arising from such scenario, which
leads to a GDB internal error due to an attempt to pop the target more
than once. With the patch, this failure is handled gracefully.

Simplify handling of auto-loaded objfile scripts.
.debug_gdb_scripts was always intended to handle more than just python,
thus the rightful home for the code that processes it is not in py-foo.c.
This is just a cleanup to move the code to a better place.
This also simplifies the handling of the ${objfile}-${suffix} auto-loaded

Unfortunately, UNWIND_NULL_ID is exported to Python as
gdb.FRAME_UNWIND_NULL_ID so we can't really eliminate it.
(I'd assume scripts just check the result of Frame.unwind_stop_reason,
and compare it to gdb.FRAME_UNWIND_NO_REASON. That at most, they'll
pass the result of Frame.unwind_stop_reason to
gdb.frame_stop_reason_string. I'd prefer to just get rid of it, but
because we make an API promise, we get to keep this around for
compatibility, in case a script does refer to gdb.FRAME_UNWIND_NULL_ID
directly.)

The memory management of bp_location->target_info.conditions|tcommands

GDB on x86_64-linux is unable to disassemble on core-file target.
$ ./gdb ./testsuite/gdb.base/corefile
(gdb) core-file ./testsuite/gdb.base/corefile.core
(gdb) disassemble main
Dump of assembler code for function main:
0x0000000000400976 <+0>: Cannot access memory at address 0x400976
However, it works if we turn code-cache off.
(gdb) set code-cache off
(gdb) disassemble main,+4
Dump of assembler code from 0x400976 to 0x40097a:
0x0000000000400976 <main+0>: push %rbp
0x0000000000400977 <main+1>: mov %rsp,%rbp
End of assembler dump.
When code-cache is off, GDB will iterate target_ops from top to bottom
and call to_xfer_partial. When current_target is "core", it will call
to_xfer_partial of target "exec", which reads the contents for
disassemble. However, dcache uses TARGET_OBJECT_RAW_MEMORY to read,
but target_xfer_partial doesn't delegate requests to beneath for
TARGET_OBJECT_RAW_MEMORY.
This patch factors out the iteration from top to bottom to a new
function, raw_memory_xfer_partial, and use it for
TARGET_OBJECT_RAW_MEMORY.
Regression tested on x86_64-linux.

* dcache.c (dcache_read_line): Use current_target.beneath
instead of ¤t_target.
* target.c (memory_xfer_partial_1): Factor code out to ...
(raw_memory_xfer_partial): ... it. New function.
(target_xfer_partial): Call raw_memory_xfer_partial if OBJECT
is TARGET_OBJECT_RAW_MEMORY.
