Complete tdep move to convert_typed_floating
Many tdep files need to perform conversions between two floating-point
types, usually when accessing FP registers. Most targets now use the
convert_typed_floating helper routine to do so. However, a small number
still use the old method of converting via a DOUBLEST. Since we want
to get rid of DOUBLEST, these targets need to be moved to the new
method as well.
The main obstacle is that for convert_typed_floating we need an actual
*type*, not just a floatformat.
In arm-tdep.c, this is very straightforward, since there is already a
type using the ARM extended floatformat.
For sh-tdep.c and sh64-tdep.c, no such type already exists, so I've
added one to the gdbarch_tdep struct as done on other targets.

Simplify floatformat_from_type
For historical reasons, the TYPE_FLOATFORMAT element is still set to hold
an array of two floatformat structs, one for big-endian and the other for
little-endian. When accessing the element via floatformat_from_type,
the code would check the type's byte order and return the appropriate
floatformat.
However, these days this is quite unnecessary, since the type's byte order
is already known at the time the type is allocated and the floatformat is
installed into TYPE_FLOATFORMAT. Therefore, we can just install the correct
version here.
Also, moves the (now trivially simple) floatformat_from_type accessor to
gdbtypes.{c,h}, since it doesn't really need to be in doublest.c now.

Make init_type/arch_type take a size in bits
This changes the interfaces to init_type and arch_type to take the
type length in bits as input (instead of as bytes). The routines
assert that the length is a multiple of TARGET_CHAR_BIT.
For consistency, arch_flags_type is changed likewise, so that now
all type creation interfaces always use length in bits.
All callers are updated in the straightforward manner.
The assert actually found a bug in read_range_type, where the
init_integer_type routine was called with a wrong argument (probably
a bug introduced with the conversion to use init_integer_type).

Use "switch_to_thread" more thoroughly on gdbserver

to gdbserver. It's a simple patch that converts occurences of:
current_thread = find_thread_ptid (ptid);
to:
switch_to_thread (ptid);
This patch also converts a simple "if" to a "gdb_assert" on
gdbserver's version of "switch_to_thread":
gdb_assert (ptid != minus_one_ptid);

Remove support for Solaris < 10 (PR gdb/22185)
Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013:
https://gcc.gnu.org/gcc-4.9/changes.html
https://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html
and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when
configured with --disable-build-with-cxx, it's time to obsolete/remove support
for Solaris < 10.
This patch does this, simplifying configure.nat along the way (only a single
sol2 configuration with variants for i386 and sparc).
Some configure checks for older Solaris versions can go, too, and the check
for libthread_db.so.1 removed:
* Since Solaris 10, dlopen has moved to libc and libdl.so is just a
filter on ld.so.1, so no need to check.
* $RDYNAMIC is already handled above (and is a no-op with Solaris ld
anyway).
Both proc-service.c and sol-thread.c lose support for (Solaris-only)
PROC_SERVICE_IS_OLD.
The attached revised patch has been tested on sparcv9-sun-solaris2.10,
sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4,
and x86_64-pc-linux-gnu.

stops as expected.

Comparing Solaris 11.4 <v7/sys/psr.h> and sparc64-tdep.c, there are more
inconsistencies:
<v7/sys/psr.h>:
#define PSR_S 0x00000080 /* supervisor mode */
#define PSR_ICC 0x00F00000 /* integer condition codes */
#define PSR_VER 0x0F000000 /* mask version */
#define PSR_IMPL 0xF0000000 /* implementation */
#define PSR_RSV 0x000FC000 /* reserved */
sparc64-tdep.c:
#define PSR_S 0x00000080
#define PSR_ICC 0x00f00000
#define PSR_VERS 0x0f000000
#define PSR_IMPL 0xf0000000
#define PSR_V8PLUS 0xff000000
#define PSR_XCC 0x000f0000
Apart from the capitalization differences that trip g++, the names
differ (PSR_VER vs. PSR_VERS), PSR_XCC is included in Solaris' PSR_RSV,
and there's no PSR_V8PLUS on Solaris either.

You cannot always print a pid_t, which can be either int or long on
Solaris, as an int.
Obviously, the ADI patch which modifies code shared between all SPARC
targets, hasn't been tested on anything but Linux/SPARC.
The patch below includes the minimal fixes necessary to unbreak the
Solaris/SPARC build.
However, as detailed in the PR, there's more breakage here: apart from
not bothering to implement ADI support on Solaris, the code contains
several more changes to shared/common SPARC code that are simply wrong
on anything but Linux/SPARC.
The patch was tested on sparcv9-sun-solaris2.10 and
sparcv9-sun-solaris2.11.4 (build and gdb/gdb gdb/gdb smoke test only).

LD/testsuite: Fix undefined symbol tests for MIPS and S+core targets
Fix commit
647d4de92e06 ("Test undefined symbols in shared libraries")
and remove "undefined symbols in shared lib (dyn reloc)" test failures
for MIPS and S+core targets.
This test assumes 3 dynamic relocation entries, however the respective
psABIs define an extra single dummy *_NONE relocation at the beginning
of the dynamic relocation table, which results in test output like the
following for MIPS:
Relocation section '.rel.dyn' at offset 0x33c contains 4 entries:
Offset Info Type Sym.Value Sym. Name
00000000 00000000 R_MIPS_NONE
00010364 00000903 R_MIPS_REL32

00000000 undef_data
00010368 00000b03 R_MIPS_REL32
00000000 undef_notype
and S+core:
Relocation section '.rel.dyn' at offset 0x274 contains 4 entries:
Offset Info Type Sym.Value Sym. Name
00000000 00000000 R_SCORE_NONE

5ffe0460 00001012 R_SCORE_REL32
00000000 undef_pfun
targets respectively, and also n64 MIPS targets pad relocation triplets
they use with extra *_NONE relocations, resulting in output like this:
Relocation section '.rel.dyn' at offset 0x4c0 contains 4 entries:
Offset Info Type Sym. Value Sym. Name
000000000000 000000000000 R_MIPS_NONE

Expect the right number of *_NONE relocations then, and adjust the total
number of relocations expected accordingly.

Allow the macw and macl instructions to be used on CPUs that have emacs support.
From PR 22123:
The common opcodes of emac and mac seem to be only implemented for mac.
To reproduce:
echo "macw %d3l,%a0l" > /tmp/dummy.S
m68k-unknown-elf-as -m5208 /tmp/dummy.S
Outputs something like:
/tmp/dummy.S: Assembler messages:
/tmp/dummy.S:1: Error: operands mismatch -- statement `macw %d3l,%a0l' ignored
This behavior occurs only if the CPU supports only emac but not explicitly mac (but emac is a superset of mac).
