The DWARF reader has had some odd code since the "physname" patches landed.
In particular, these patches caused PR symtab/12707; namely, they made
it so "set print demangle off" no longer works.
This patch attempts to fix the problem. It arranges to store the
linkage name on the symbol if it exists, and it changes the DWARF
reader so that the demangled name is no longer (usually) stored in the
symbol's "linkage name" field.
c-linkage-name.exp needed a tweak, because it started working
correctly. This conforms to what I think ought to happen, so this
seems like an improvement here.
compile-object-load.c needed a small change to use
symbol_matches_search_name rather than directly examining the linkage
name. Looking directly at the name does the wrong thing for C++.
There is still some name-related confusion in the DWARF reader:
* "physname" often refers to the logical name and not what I would
consider to be the "physical" name;
* dwarf2_full_name, dwarf2_name, and dwarf2_physname all exist and
return different strings -- but this seems like at least one name
too many. For example, Fortran requires dwarf2_full_name, but other
languages do not.
* To my surprise, dwarf2_physname prefers the form emitted by the
demangler over the one that it computes. This seems backward to me,
given that the partial symbol reader prefers the opposite, and it
seems to me that this choice may perform better as well.
I didn't attempt to clean up these things. It would be good to do,
but whenever I contemplate it I get caught up in dreams of truly
rewriting the DWARF reader instead.

This commit extends the CLI a bit for multi-target, in three ways.
#1 - New "info connections" command.
This is a new command that lists the open connections (process_stratum
targets). For example, if you're debugging two remote connections, a
couple local/native processes, and a core dump, all at the same time,
you might see something like this:
(gdb) info connections
Num What Description
1 remote 192.168.0.1:9999 Remote serial target in gdb-specific protocol
2 remote 192.168.0.2:9998 Remote serial target in gdb-specific protocol
* 3 native Native process
4 core Local core dump file
#2 - New "info inferiors" "Connection" column
You'll also see a new matching "Connection" column in "info
inferiors", showing you which connection an inferior is bound to:
(gdb) info inferiors
Num Description Connection Executable
1 process 18526 1 (remote 192.168.0.1:9999) target:/tmp/a.out
2 process 18531 2 (remote 192.168.0.2:9998) target:/tmp/a.out
3 process 19115 3 (native) /tmp/prog1
4 process 6286 4 (core) myprogram
* 5 process 19122 3 (native) /bin/hello
#3 - Makes "add-inferior" show the inferior's target connection
"add-inferior" now shows you the connection you've just bound the
inferior to, which is the current process_stratum target:
(gdb) add-inferior
[New inferior 2]
Added inferior 2 on connection 1 (extended-remote localhost:2346)

The documentation for make-breakpoint from the Guile API and the `spec'
variant of the gdb.Breakpoint constructor from the Python API state that
the format acceptable for location strings is the same as that accepted
by the break command. However, using the -probe qualifier at the
beginning of the location string causes a GDB internal error as it
attempts to decode a probe location in the wrong code path. Without this
functionality, there doesn't appear to be another way to set breakpoints
on probe points from Python or Guile scripts.
This patch introduces a new helper function that returns a
breakpoint_ops instance appropriate for a parsed location and updates
the Guile and Python bindings to use said function, rather than the
current hard-coded use of bkpt_breakpoint_ops. Since this logic is
duplicated in the handling of the `break' and `trace' commands, those
are also updated to call into the new helper function.

A following patch will introduce options for the "backtrace" command,
based on some "set print" and "set backtrace" settings. There's one
setting in particular that is a bit annoying if we want to describe
the backtrace options and the settings commands using the same data
structures:
"set print raw frame-arguments"
The problem is that space between "raw" and "frame-arguments".
Calling the option
"bt -raw frame-arguments"
would be odd. So I'm calling the option
"bt -raw-frame-arguments"
instead.
And for consistency, this patch renames the set/show commands to:
"set print raw-frame-arguments"
"show print raw-frame-arguments"
I.e., dash instead of space. The old commands are left in place, but
marked deprecated.
We need to adjust a couple testcases, because the relevant tests use
gdb_test_no_output and the old commands are no longer silent:
(gdb) set print raw frame-arguments on
Warning: command 'set print raw frame-arguments' is deprecated.
Use 'set print raw-frame-arguments'.

In https://sourceware.org/ml/gdb-patches/2017-12/msg00215.html, Jan
pointed out that the scalar printing patches caused a regression in
scm-ports.exp on x86.
What happens is that on x86, this:
set sp_reg [get_integer_valueof "\$sp" 0]
... ends up setting sp_reg to a negative value, because
get_integer_valueof uses "print/d":
print /d $sp
$1 = -11496
Then later the test suite does:
gdb_test "guile (print (seek rw-mem-port (value->integer sp-reg) SEEK_SET))" \
"= $sp_reg" \
"seek to \$sp"
... expecting this value to be identical to the saved $sp_reg value.
However it gets:
guile (print (seek rw-mem-port (value->integer sp-reg) SEEK_SET))
= 4294955800
"print" is just a wrapper for guile's format:
gdb_test_no_output "guile (define (print x) (format #t \"= ~A\" x) (newline))"
The seek function returns a scm_t_off, the printing of which is
handled by guile, not by gdb.
Tested on x86-64 Fedora 26 using an ordinary build and also a -m32
build.

When running tests in parallel, each test puts its generated files in a
different directory, under "outputs". I think it would be nice if it
was always the case, as it would isolate the test cases a bit more. An
artifact created by a test wouldn't get overwritten by another test.
Also, it makes it easier to clean up. A lot of executables are left all
over the place because their names do not appear in gdb.*/Makefile. If
everything is in "outputs", then we just have to delete that directory
(which we already do).
At the same time it makes the gdb.foo directories and their Makefiles
useless in the build directory, since they are pretty much only used for
cleaning.

This patch is to remove the third argument of gdb_remote_download, so
that gdb_remote_download can return the correct location.
Further, these tests only copy .scm files to a different name. From what
I can tell from the comments, looks we do this to avoid clobbering file
in in-tree build. However, if source and dest of copy are the same, the
operation is no-op. So it makes few sense to copy .scm files to a
different names. I tried in-tree build/test with this patch, test
result isn't changed.

I see the following two fails on arm-none-eabi target, because argv[0]
isn't available.
print argv[0]^M
$1 = 0x1f78 "/dev/null"^M
(gdb) FAIL: gdb.base/argv0-symlink.exp: kept file symbolic link name
print argv[0]^M
$1 = 0x1f78 "/dev/null"^M
(gdb) FAIL: gdb.base/argv0-symlink.exp: kept directory symbolic link name
My first thought is to check [target_info exists noargs], and skip the
test if it returns true. However, noargs is set in gdbserver board
files, so argv0-symlink.exp will be skipped on gdbserver board file.
The change is too aggressive.
When the program is running with gdbserver, argv[1] to argv[N] aren't
available, but argv[0] is. Fortunately, argv0-symlink.exp only
requires argv[0]. argv0-symlink.exp can be run with gdbserver board
file, as what we do now.
What we need to check is whether argv[0] is available, so I add a new
proc gdb_has_argv0 to do so by starting a program, and check
argc/argv[0] to see whether argv[0] is available.
Dan fixed the similar problem by checking noargs, which is too strong.

Some testcases, mostly gdb.reverse ones, assume the presence of a
'/' directory separator before the source file name. This is
incorrect for mingw32 hosts, generating false failures for those
tests.
I attempted to catch most of the occurrences of the pattern
".*/$srcfile" and replaced them with ".*$srcfile". The latter
is used elsewhere in the testsuite. The resulting patch is attached.
I also see other occurrences of the same assumption throughout the
testsuite, but usually they are arguments for function calls and i
seem to recall either the test harness or GDB deals with those
paths properly.

printing command name.
* cli/cli-decode.h (cli_user_command_p): Declare new function.
* cli/cli-decode.c (cli_user_command_p): Create helper function
to verify whether cmd_list_element is a user-defined command.
gdb/testsuite/Changelog:
* gdb.base/commands.exp: Add tests to verify user-defined
commands with empty bodies.
* gdb.python/py-cmd.exp: Test that we don't show user-defined
python commands in `show user command`.
* gdb.python/scm-cmd.exp: Test that we don't show user-defined
scheme commands in `show user command`.
I see the following fails on arm-none-eabi target,
print sn^M
$14 = 0x0 <_ftext>^M
(gdb) FAIL: gdb.python/py-value.exp: print sn
print sn^M
$14 = 0x0 <_ftext>^M
(gdb) FAIL: gdb.guile/scm-value.exp: print sn
as <_ftext> is unexpected. This patch is to set print symbol off to
avoid printing this.
gdb/testsuite:

* gdb.guile/scm-value.exp (test_lazy_strings): Set print
symbol off.
* gdb.python/py-value.exp (test_lazy_strings): Likewise.
I find some gdb.python tests fail on arm-none-eabi target, because the
tests assume that memory on address 0x is inaccessible. Some tests
(in gdb.base) are aware of this, so do a "x 0" check first. However,
the code is copy-n-paste.
This patch is to move the "x 0" check to a procedure in lib/gdb.exp,
and get needed tests call it. The original code matches pattern
"0x0:\[ \t\]*Error accessing memory address 0x0\r\n$gdb_prompt $", but
I remove it from the new proc is_address_zero_readable, because GDB
doesn't emit such message any more.

* gdb.guile/scm-value.exp (test_value_in_inferior): Likewise.
* gdb.python/py-value.exp (test_value_in_inferior): Likewise.
* gdb.base/hbreak-unmapped.exp: Return if
is_address_zero_readable returns true.
* gdb.base/signest.exp: Likewise.
* gdb.base/signull.exp: Likewise.
* gdb.base/sigbpt.exp: Likewise.

* lib/gdb.exp (is_address_zero_readable): New proc.
* guile/scm-param.c (pascm_parameter_defined_p): New function.
(gdbscm_register_parameter_x): Call it. Raise error for pre-existing
parameters.
testsuite/
* gdb.guile/scm-parameter.exp: Add tests for trying to create
previously existing parameter, and previously ambiguously spelled
parameter.
* data-directory/Makefile.in (GUILE_FILES): Add support.scm.
* guile/lib/gdb/support.scm: New file.
* guile/guile.c (gdbscm_init_module_name): Change to "gdb".
* guile/lib/gdb.scm: Load gdb/init.scm as an include file.
All uses updated.
* guile/lib/gdb/init.scm (SCM_ARG1, SCM_ARG2): Moved to support.scm.
All uses updated.
(%assert-type): Ditto, and renamed to assert-type.
(%exception-print-style): Delete.
testsuite/
* gdb.guile/types-module.exp: Add tests for wrong type arguments.
Support for smobs as goops classes is changing in guile 2.2.
We may eventually switch to using structs instead of smobs,
so remove any claim we support goops or generics for now.
* gdb.guile/scm-generics.exp: Delete.
* guile/scm-value.c (gdbscm_value_dynamic_type): Use coerce_ref to
dereference TYPE_CODE_REF values.
testsuite/
* gdb.guile/scm-value.c: Improve test case.
* gdb.guile/scm-value.exp: Add new test.
