b8bca85b33 MIPS/GAS: Remove extraneous install_insn' call from append_insn'
Complement:

commit 1e91584932
Author: Richard Sandiford <rdsandiford@googlemail.com>
Date:   Wed Mar 9 09:17:02 2005 +0000

<https://sourceware.org/ml/binutils/2005-03/msg00217.html>, ("Rework
MIPS nop-insertion code, add -mfix-vr4130 [5/11]"), and remove a call to
`install_insn' from `append_insn', which as from that change has become
redundant.  This is because such a call, to place an instruction's bit
pattern in output, is already made from `move_insn', called from
`add_relaxed_insn' or `add_fixed_insn' as appropriate, either of which
now always is and has to be made from `append_insn' before the repeated
call to `install_insn' is made.  Previously the place where this second
invocation is made was the only one where the output stream was updated,
although the update was made inline rather than with a function call.

Remove the repeated call then, to reclaim some performance.

	`install_insn' call.

4f19a0e6b4 Fix of default lookup for "this" symbol.
Using the default lookup for the symbol "this" might lead to segmentation
fault in GDB.
Some languages, e.g. Fortran, use as default lookup routine the C++
routines.
For those languages "this" can be the instance of a class or even the
definition of a class.
When an instance of a class having the name "this" is evaluated
in GDB a segmentation fault was observed.

As example of the issue take into consideration the Fortran code:
  type foo
    real :: a
    type(bar) :: x
    character*7 :: b
  end type foo
  type(foo) :: this

Issue appears when evaluating the variable "this" in GDB.

Within the language definition structure there is a field that represents
the name of the special symbol used for the C++ "this" for the language
being described.
The fix presented here takes into account the aforementioned field. In the
case the aforementioned field is NULL "this" is not represented in the
language described and the lookup should return a null_block_symbol.

Tests: Performed tests with gfortran and ifort.

f0464b231f Remove extra output directory level for Ada tests
The output of Ada tests create a layout where the test name
("formatted_ref" in this example) appears twice:

outputs
└── gdb.ada
    └── formatted_ref
        └── formatted_ref
            ├── b~formatted_ref.adb
            ├── b~formatted_ref.ads
            ├── b~formatted_ref.ali
            ├── b~formatted_ref.o
            ├── defs.ali
            ├── defs.o
            ├── formatted_ref
            ├── formatted_ref.ali
            └── formatted_ref.o

This causes a problem when testing with the native-gdbserver board, when
the binary has the same name as the test.  When gdb_remote_download is
called to upload the compiled binary, the implementation for
native-gdbserver copies it in the standard output directory (in
outputs/gdb.ada/formatted_ref).  However, there is already a directory
named formatted_ref in there, so the copy fails and gdbserver isn't able
to load the binary.

This patch bypasses the problem by removing the extra directory level.
The compiled binary will already be in its final location in the
standard output directory, so the copy will effectively be a no-op.

1040b979bc [ARM] Fix endless recursion on calculating CPRC candidate
When GDB determines whether type T can be part of candidate for
passing and returning in VFP registers, it calls
arm_vfp_cprc_sub_candidate recursively.  However, if type T has
self-reference field, like,

class C
{
  static C s;
};

arm_vfp_cprc_sub_candidate won't return.  This fix is to skip calling
arm_vfp_cprc_sub_candidate if the field is static.

09c98b448f Optimize memory_xfer_partial for remote
Some analysis we did here showed that increasing the cap on the
transfer size in target.c:memory_xfer_partial could give 20% or more
improvement in remote load across JTAG.  Transfer sizes were capped
to 4K bytes because of performance problems encountered with the
restore command, documented here:

https://sourceware.org/ml/gdb-patches/2013-07/msg00611.html

and in commit 67c059c29e ("Improve performance of large restore
commands").

The 4K cap was introduced because in a case where the restore command
requested a 100MB transfer, memory_xfer_partial would repeatedy
allocate and copy an entire 100MB buffer in order to properly handle
breakpoint shadow instructions, even though memory_xfer_partial would
actually only write a small portion of the buffer contents.

A couple of alternative solutions were suggested:
* change the algorithm for handling the breakpoint shadow instructions
* throttle the transfer size up or down based on the previous actual
  transfer size

I tried implementing the throttling approach, and my implementation
reduced the performance in some cases.

This patch implements a new target function that returns that target's
limit on memory transfer size.  It defaults to ULONGEST_MAX bytes,
because for native targets there is no marshaling and thus no limit is
needed.  For remote targets it uses get_memory_write_packet_size.

gdb/ChangeLog:

	* remote.c (remote_get_memory_xfer_limit): New function.
	* target-delegates.c: Regenerate.
	* target.c (memory_xfer_partial): Call
	target_ops.to_get_memory_xfer_limit.
	* target.h (struct target_ops)
	<to_get_memory_xfer_limit>: New member.

93d8990cba [AArch64] Fix +nofp16 handling
Feature flag handling was not perfect, +nofp16 disabled fp
instructions too.

New feature flag macros were added to check features with multiple
bits set (matters for FP_F16 and SIMD_F16 opcode feature tests).
The unused AARCH64_OPCODE_HAS_FEATURE was removed, all checks should
use one of the AARCH64_CPU_HAS_* macros.  AARCH64_CPU_HAS_FEATURE
now checks all feature bits.

The aarch64_features table now contains the dependencies as
a separate field (so when the feature is enabled all dependencies
are enabled and when it is disabled everything that depends on it
is disabled).

Note that armv8-a+foo+nofoo is not equivalent to armv8-a if
+foo turns on dependent features that nofoo does not turn off.
