When a node is removed from a splay tree, the splay tree was
not using the function splay_tree_delete_key_fn to release the key.
This was causing a leak, fixed by Tom Tromey.
This patch fixes another key leak, that happens when a key equal to
a key already present is inserted. In such a case, we have to release
the old KEY.
Note that this is based on the assumption that the caller always
allocates a new KEY when doing an insert.
Also, clarify the documentation about when the release functions are
called.

This patch is part of a series of patches to introduce a few changes to the
Armv8.5-A Memory Tagging Extension. This patch removes the LDGV and STGV
instructions. These instructions needed special infrastructure to support
[base]! style for addressing mode. That is also removed now.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header

PPC_INT_FMT is redundant now that bfd.h pulls in inttypes.h if
available. Apparently MacOS Mojave defines int64_t as long long even
though long is also 64 bits, which confuses the logic selecting
PPC_INT_FMT (and BFD_PRI64 too). Hopefully inttypes.h is available on
Mojave.

Linkers group input note sections with the same name into one output
note section with the same name. One output note section is placed in
one PT_NOTE segment. New linkers merge all input .note.gnu.property
sections into one output .note.gnu.property section with a single
NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older
linkers treat input .note.gnu.property section as a generic note section
and just concatenate all input .note.gnu.property sections into one
output .note.gnu.property section without merging them, we may
see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which
are invalid.
GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such
that linker sets the bit for non-relocatable outputs. But it isn't
sufficient:
1. It doesn't cover generic properties.
2. When -mx86-used-note=yes is passed to x86 assembler, the
GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED
property in object file and older linkers generate invalid
NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit
set.
I am proposing the following changes:
1. Add PT_GNU_PROPERTY segment type:
# define PT_GNU_PROPERTY (PT_LOOS + 0x474e553)
which covers .note.gnu.property section.
2. Remove GNU_PROPERTY_X86_UINT32_VALID.

This patch started off just adding the warnings in tc-ppc.c about
incorrect usage of @l, @h and @ha in instructions that don't have
16-bit D-form fields. That unfortunately showed up three warnings in
ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like
e_li r3, IV_table@l+0x00
which was being assembled to
8: 70 60 00 00 e_li r3,0
a: R_PPC_ADDR16_LO IV_table
The ADDR16_LO reloc is of course completely bogus on e_li, which has
a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit
in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800.
Applying an ADDR16_LO reloc to the instruction potentially changes
the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i,
e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis,
e_and2is, or some invalid encodings.
Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was
added 2017-09-05 but I can't see code in gas to generate the
relocation. In any case, VLE_ADDR20 probably doesn't have the correct
semantics for @l since ideally you'd want an @l to pair with @h or @ha
to generate a 32-bit constant. Thus @l should only produce a 16-bit
value, I think. So we need some more relocations to handle e_li it
seems, or as I do in this patch, modify the behaviour of existing
relocations when applied to e_li instructions.

The RISC-V assembler generates fake labels with the name '.L0 ' as
part of the debug information (see
gas/config/tc-riscv.h:FAKE_LABEL_NAME).
The problem is that currently, when disassembling an object file, the
output looks like this (this is an example from the GDB testsuite, but
is pretty representative of anything with debug information):

The frequent repeated '.L0 ' labels are pointless, as they are
non-unique there's no way to match a use of '.L0 ' to its appearence
in the output, so we'd be better off just not printing it at all.
That's what this patch does by defining a 'symbol_is_valid' method for
RISC-V. With this commit, the same disassembly now looks like this:

In order to share the fake label between the assembler and the
libopcodes library, I've added some new defines RISCV_FAKE_LABEL_NAME
and RISCV_FAKE_LABEL_CHAR in include/opcode/riscv.h. I could have
just moved FAKE_LABEL_NAME to the include file, however, I thnk this
would be confusing, someone working on the assembler would likely not
expect to find FAKE_LABEL_NAME defined outside of the assembler source
tree. By introducing the RISCV_FAKE_LABEL_* defines I can leave the
assembler standard FAKE_LABEL_ defines in the assembler source, but
still share the RISCV_FAKE_LABEL_* with libopcodes.

This patch is part of the patch series to add support for ARMv8.5-A
Memory Tagging Extensions which is an optional extension to
ARMv8.5-A and is enabled using the +memtag command line option.
This patch add support to the Bulk Allocation Tag instructions from
MTE. These are the following instructions added in this patch:
- LDGV <Xt>, [<Xn|SP>]!
- STGV <Xt>, [<Xn|SP>]!
This needed a new kind of operand for the new addressing [<Xn|SP>]!
since this has no offset and only takes a pre-indexed version.
Hence AARCH64_OPND_ADDR_SIMPLE_2 and ldtdgv_indexed are introduced.
(AARCH64_OPND_ADDR_SIMPLE fulfilled the no offset criteria but does
not allow writeback). We also needed new encoding and decoding
functions to be able to do the same.

This patch adds support for the mitigation for Spectre Variant 4 by
adding the PSTATE bit SSBS which are accessible using MSR and MRS
instructions. Although this is a mandatory addition to the ARMv8.5-A,
it is permitted to be added to any version of the ARMv8 architecture.
This is enabled using the command line option of +ssbs for older
versions.

This patch adds the data processing instructions that are new to
ARMv8.5-A.
1) There are 2 instructions: xaflag, axflag, that are added to
manipulate the states of the flag and are used to convert between the
Arm representation and the fcmp representation.
2) The other instructions are rounding instructions which have 8
versions based on whether the floating-point number is a
Single-Precision or Double-Precision number, whether the target
integer is a 32-bit or 64-bit integer and whether the rounding mode is
the ambient rounding mode or to zero. Each of these instruction is
available in both Scalar and Vector forms.
Since both 1) and 2) have separate identification mechanism and it is
permissible that a ARMv8.4 compliant implementation may include any
arbitrary subset of the ARMv8.5 features unless otherwise specified,
new feature bits are added.

This patch, along with previous patches in the series, supports
putting the ELF file header and program headers in a PT_LOAD without
sections.
Logic governing whether headers a loaded has changed a little: The
primary reason to include headers is now the presence of
SIZEOF_HEADERS in a linker script. However, to support scripts that
may have reserved space for headers by hand, we continue to add
headers whenever the first section address is past the end of headers
modulo page size.

This patch adds the Execution and Data Prediction Restriction
instructions (that is, cfprctx, dvprxtc, cpprctx). These are all
aliases to MCR and are disassembled as such.
This instruction is retrospectively made optional for all versions of
the architecture from ARMv8.0 to ARMv8.4 and is mandatory from
ARMv8.5. Hence adding a new +predres for older versions of the
architecture.

This patch adds the new instruction and relocation as per proposal:
https://openrisc.io/proposals/ladrp
This is to be added to the spec in an upcoming revision. The new instruction
l.adrp loads the page offset of the current instruction offset by
a 21-bit immediate shifted left 13-bits. This is meant to be used with
a 13-bit lower bit page offset. This allows us to free up the got
register r16.
l.adrp r3, foo
l.ori r4, r3, po(foo)
l.lbz r5, po(foo)(r3)
l.sb po(foo)(r3), r6
The relocations we add are:
- BFD_RELOC_OR1K_PLTA26 For PLT jump relocation with PLT entry
asm: plta() implemented using l.ardp, meaning
no need for r16 (the GOT reg)
- BFD_RELOC_OR1K_GOT_PG21 Upper 21-bit Page offset got address
asm: got()
- BFD_RELOC_OR1K_TLS_GD_PG21 Upper 21-bit Page offset with TLS General
asm: tlsgd() Dynamic calculation
- BFD_RELOC_OR1K_TLS_LDM_PG21 Upper 21-bit Page offset with TLS local
asm: tlsldm() dynamic calculation
- BFD_RELOC_OR1K_TLS_IE_PG21 Upper 21-bit Page offset with TLS Initial
asm: gottp() Executable calculation
- BFD_RELOC_OR1K_PCREL_PG21 Default relocation for disp21 (l.adrp
instructions)
- BFD_RELOC_OR1K_LO13 low 13-bit page offset relocation
asm: po() i.e. mem loads, addi etc
- BFD_RELOC_OR1K_SLO13 low 13-bit page offset relocation
asm: po() i.e. mem stores, with split immediate
- BFD_RELOC_OR1K_GOT_LO13, low 13-bit page offset with GOT calcs
asm: gotpo()
- BFD_RELOC_OR1K_TLS_GD_LO13 Lower 13-bit offset with TLS GD calcs
asm: tlsgdpo()
- BFD_RELOC_OR1K_TLS_LDM_LO13 Lower 13-bit offset with TLS LD calcs
asm: tlsldmpo()
- BFD_RELOC_OR1K_TLS_IE_LO13 Lower 13-bit offset with TLS IE calcs
asm: gottppo()

This patch adds the verification rules for move prefix constraints.
The Arm SVE instruction MOVPRFX introduces[1] constraints on the instruction at
PC+4. Particularly the following constraints are handled by this patch
* MOVPRFX must be followed by an instruction.
* MOVPRFX can only be followed by non-layout altering directives.
* MOVPRFX destination register MUST be used as the destination register in the
instruction at PC+4, and is not allowed to be used in any other position other than
destructive input. This includes registers that architecturally overlap. e.g. x1
should be treated as z1.
* MOVPRFX must be followed by a restricted set of SVE instructions.
* The size of the destination register of MOVPRFX must be equal to that of
the operation at PC+4.
* The predicate register and operation of MOVPRFX must match that of the instruction
at PC+4
* The predicated instruction at PC+4 must use the merging predicate.
* Architectural aliases and pseudo-instructions need to be supported as well.
* MOVPRFX cannot be the last instruction in a sequence
Any failure to adhere to any of these constrains will emit an assembly warning
and a disassembly note.

The current verifiers only take an instruction description and encoded value as
arguments. This was enough when the verifiers only needed to do simple checking
but it's insufficient for the purposes of validating instruction sequences.
This patch adds the required arguments and also a flag to allow a verifier to
distinguish between whether it's being run during encoding or decoding. It also
allows for errors and warnings to be returned by a verifier instead of a simple
pass/fail.
