Previously VQ was of type long. Using uint64_t ensures it always matches the
same type as the VG register.
Note that in the Linux kernel, VQ is 16bits. We cast it up to 64bits
immediately after reading to ensure we always use the same type throughout
the code.

This changes "backslashable" and "represented" in cp-name-parser.y to
be const. This lets the compiler make them read-only (though in my
build it seems that GCC inlines them, which seems even better).

* cp-name-parser.y (backslashable, represented): Now const.
This changes cp-name-parser.y to include parser-defs.h, removing the
copy-pasted declaration of parser_fprintf. This can be done now that
cp-name-parser.y does not define any global variables.

This changes cp-name-parser.y to be a pure parser.
Originally I had thought that doing this would mean that gdb would
always require Bison. However, I've learned that Byacc supports some
of the Bison extensions in this area. So, the new code ought to work
reasonably well with both.
Note that the Byacc documentations says:
%pure-parser
Most variables (other than yydebug and yynerrs) are allocated
on the stack within yyparse, making the parser reasonably
reentrant.
In our case this is ok, first because gdb does not yet actualy require
reentrancy, and second because gdb does not use yynerrs.

This required declaring parser_fprintf in cp-name-parser.y.
parser-defs.h can't be included here because parser-defs.h declares a
global "lexptr", which conflicts with the local one in
cp-name-parser.y. This is only temporary, and will be cleaned up

Trying to insert a breakpoint using *FUNC'address with an Ada program
and then running the program until reaching that breakpoint currently
yields the following behavior:
(gdb) break *a'address
Breakpoint 1 at 0x40240c: file a.adb, line 1.
(gdb) run
[1] + 27222 suspended (tty output) /[...]/gdb -q simple_main
Unsuspending GDB then shows it was suspended trying to report
the following error:
Starting program: /home/takamaka.a/brobecke/ex/simple/a
Error in re-setting breakpoint 1: Unmatched single quote.
Error in re-setting breakpoint 1: Unmatched single quote.
Error in re-setting breakpoint 1: Unmatched single quote.
[Inferior 1 (process 32470) exited normally]
The "a'address" is Ada speak for function A's address ("A" by
itself means the result of calling A with no arguments). The
transcript above shows that we're having problems trying to
parse the breakpoint location while re-setting it. As a result,
we also fail to stop at the breakpoint.
Normally, breakpoint locations are evaluated with the current_language
being set to the language of the breakpoint. But, unfortunately for us,
what happened in this case is that parse_exp_in_context_1 calls
get_selected_block which eventually leads to a call to select_frame
because the current_frame hadn't been set yet. select_frame then
finds that our language_mode is auto, and therefore changes the
current_language to match the language of the frame we just selected.
In our case, the language chosen was 'c', which of course is not
able to parse an Ada expression, hence the error.
This patch prevents this by forcing the language_mode to manual
before we call breakpoint_re_set_one.

TYPE_TAG_NAME has been an occasional source of confusion and bugs. It
seems to me that it is only useful for C and C++ -- but even there,
not so much, because at least with DWARF there doesn't seem to be any
way to wind up with a type where the name and the tag name are both
non-NULL and different.
So, this patch removes TYPE_TAG_NAME entirely. This should save a
little memory, but more importantly, it simplifies this part of gdb.
A few minor test suite adjustments were needed. In some situations
the new code does not yield identical output to the old code.

Currently dwarf2read.c will pass the CU's language to

code, adding an overload to c_type_print. Some uses of

First of all there's no point in having separate Cpu386 templates - the
respective SReg3 registers can't be specified for pre-386 anyway; see
parse_real_register().
And then we can also make use of D here for the memory forms of the
insn. This cannot be done for the non-64bit GPR forms because of the
IgnoreSize that cannot be dropped from the to-SREG variant.
All REX bits can be specified via individual prefixes. Redundancy should
only be reported on a per-bit basis.
Note that I originally had further checks added to the test case,
checking the effect also on PDEP. I had to strip those, because my patch
to correctly handle those
(https://sourceware.org/ml/binutils/2017-02/msg00280.html) was rejected.
I continue to think that there should not be any new prefix introduced
to handle the VEX case - whether the encoding of an insn requires VEX et
al should not be of immediate interest to the programmer.
... as is already done elsewhere: There's no need for the use of
operand_type_equal() here - the bit identifying control registers isn't
used for any other purposes.
The control register is never expressed by REX.B; this bit only affects
the involved GPR. Also only one of the operands can have its "control"
flag set, so only check the correct operand.
It's long bothered me that setting a Python parameter from the CLI
will print the "set" help text by default. I think usually "set"
commands should be silent. And, while you can modify this behavior a
bit by providing a "get_set_string" method, if this method returns an
empty string, a blank line will be printed.
This patch removes the "help" behavior and changes the get_set_string
behavior to avoid printing a blank line. The code has a comment about
preserving API behavior, but I don't think this is truly important;
and in any case the workaround -- implementing get_set_string -- is
trivial.

For Alpha, we currently define GDB_ARCH_IS_TRAP_BRKPT and
GDB_ARCH_IS_TRAP_HWBKPT both to ((X) == TRAP_BRKPT), which causes the
two if branches to be duplicated.
Alpha doesn't have hardware breakpoints, so the Linux kernel for Alpha
never sets si_code to TRAP_HWBKPT. We can just remove the special
definitions of these macros for __alpha__ and rely on the default ones.
Since the kernel will never report TRAP_HWBKPT, we will just never enter
the "hardware breakpoint" branch on Alpha (which is fine since it
doesn't have them).

Use the last endianness explicitly selected, either by choosing a binary
file or with the `set endian' command, for future automatic selection.
As observed with the `gdb.base/step-over-no-symbols.exp' test case when
discarding the binary file even while connected to a live target the
endianness automatically selected is reset to the GDB target's default,
even if it does not match the endianness of the target being talked to.
For example with a little-endian MIPS target and the default endianness
being big we get this:

which shows that with the removal of the executable debugged the
endianness of $pc still at `main' gets swapped and the value in that
register is now incorrectly interpreted as 0x40084000 rather than
0x400840 as shown earlier on with the `break' command. Consequently the
debug session no longer works as expected, until the endianness is
overridden with an explicit `set endian little' command.
This will happen while working with any target hardware whose endianness
does not match the default GDB target's endianness guessed and recorded
for a later use in `initialize_current_architecture'.
Given that within a single run of GDB it is more likely that consecutive
target connections will use the same endianness than that the endianness
will be swapped between connections, it makes sense to preserve the last
endianness explicitly selected as the automatic default. It will make a
session like above, where an executable is removed, work correctly and
will retain the endianness for a further reconnection to the target.
And the new automatic default will still be overridden by subsequently
choosing a binary to debug, or with an explicit `set endian' command.
With the change in place the test case above completes successfully:

In our fix for tagged pointer support our agreed approach was to sign
extend user-space address after clearing tag bits. This is not same
for all architectures and this patch allows sign extension for
addresses on targets which specifically set significant_addr_bit.
