MIPS16e2: Add MIPS16e2 ASE support
Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:
1. A new ELF ASE flag to mark MIPS16e2 binaries.
2. MIPS16e2 instruction assembly support, including a relaxation update
to use LUI rather than an LI/SLL instruction pair for loading the
high part of 32-bit addresses.
3. MIPS16e2 instruction disassembly support, including updated rules for
extended forms of instructions that are now subdecoded and therefore
do not alias to the original MIPS16 ISA revision instructions even
for encodings that are not valid in the MIPS16e2 instruction set.
Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops. Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.

MIPS16/GAS: Improve [32768,65535] out-of-range operand error diagnostics
Improve out-of-range operand error diagnostics for invalid values in the
[32768,65535] range used for a signed 16-bit immediate, making the
message consistent with that used for other invalid values, e.g.:
foo.s:1: Error: operand 2 must be an immediate expression `addiu $2,$gp,32768'
foo.s:2: Error: invalid operands `lw $2,32768($gp)'
vs:
foo.s:3: Error: operand 3 out of range `addiu $2,$gp,-32769'
foo.s:4: Error: operand 2 out of range `lw $2,-32769($gp)'
This case does not currently trigger however, for two reasons.
First, for regular MIPS and microMIPS assembly in the case of no match
caused by `match_int_operand' here, the function is always called again
from `mips_ip' via `match_insns', `match_insn' and then `match_operand'
for the same opcode table's entry with `lax_match' set to TRUE, in which
case the attempt to match succeeds and no error is issued.
Second, in the case of MIPS16 assembly no call to `match_int_operand' is
made at all for signed 16-bit immediates, because such immediates are
currently only matched with extensible instructions, and these are
handled in `match_mips16_insn' via `match_expression' directly rather
than via `match_operand'.
This will change for MIPS16 code with MIPS16e2 support introduced, where
non-extensible instructions accepting signed 16-bit immediates will be
added, so make the case work well right from the start:
foo.s:1: Error: operand 3 out of range `addiu $2,$gp,32768'
foo.s:2: Error: operand 2 out of range `lw $2,32768($gp)'

MIPS16/GAS: Improve non-immediate operand error diagnostics
Improve non-immediate operand error diagnostics for extensible MIPS16
instructions and make it match corresponding regular MIPS and microMIPS
handling, e.g:
$ cat addiu.s
addiu $4, $3, $2
$ as -o addiu.o addiu.s
addiu.s: Assembler messages:
addiu.s:1: Error: operand 3 must be an immediate expression `addiu $4,$3,$2'
$ as -mips16 -o addiu.o addiu.s
addiu.s: Assembler messages:
addiu.s:1: Error: invalid operands `addiu $4,$3,$2'
$
To do so observe that for extensible MIPS16 instructions and a non-PC
relative operand this case is handled by an explicit OT_INTEGER check in
`match_mips16_insn' returning a failure right away and consequently
preventing a call to `match_expression' from being made. As from commit
d436c1c2e889 ("Improve error reporting for register expressions"),
<https://sourceware.org/ml/binutils/2013-08/msg00134.html>, however the
check has become redundant as `match_expression' now only ever returns
success for OT_INTEGER argument tokens, and a special case of an OT_CHAR
`(' token already handled by `match_mips16_insn' just ahead of the
`match_expression' call. Previously it also returned success for OT_REG
argument tokens.
Let the call to `match_expression' always happen then, yielding the same
failure for the affected cases, however with more accurate diagnostics
provided by the call making reporting consistent:
$ as -mips16 -o addiu.o addiu.s
addiu.s: Assembler messages:
addiu.s:1: Error: operand 3 must be an immediate expression `addiu $4,$3,$2'

Avoid exponential behavior in rust_evaluate_subexp
The STRUCTOP_STRUCT case in rust_evaluate_subexp would evaluate its
LHS, and then, if it did not need Rust-specific treatment, it would
back up and re-evaluate the entire STRUCTOP_STRUCT part of the
expression using evaluate_subexp_standard. This yields exponential
behavior and causes some expressions to evaluate extremely slowly.
The fix is to simply do the needed work inline.
This is PR rust/21483.

x86-64: Improve PLT generation and synthetic PLT symbols
On x86-64, the procedure linkage table (PLT) is used to
1. Call external function.
2. Call internal IFUNC function. The best implementation is selected
for the target processor at run-time.
3. Act as the canonical function address.
4. Support LD_AUDIT to audit external function calls.
5. Support LD_PROFILE to profile external function calls.
PLT looks like:
PLT0: push GOT[1]
jmp *GOT[2]
nop
PLT1: jmp *GOT[name1_index]
push name1_reloc_index
jmp PLT0
GOT is an array of addresses. Initially the GOT entry of name1 is
filled with the address of the "push name1_reloc_index" instruction.
The function, name1, is called via "jmp *GOT[name1]" in the PLT entry.
Even when lazy binding is disabled by "-z now", the PLT0 entry may
still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for
canonical function address.
When linker is invoked with "-z bndplt", a different PLT layout in .plt
is used:
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
PLT1: push name1_reloc_index
bnd jmp PLT0
nop
together with a second PLT section, .pl.bnd:
PLT1: bnd jmp *GOT[name1_index]
nop
where the GOT entry of name1 is filled with the address of the push
instruction of the corresponding entry in .plt.
1. With lazy binding, when the external function, name1, is called the
first time, dynamic linker is called via PLT0 to update GOT[name1_index]
with the actual address of name1 and transfers control to name1
afterwards.
2. PLT is also used to call a local IFUNC function, name1, run-time
loader updates GOT[name1_index] when loading the module.
This patch
1. Remove PLT layout configurations from x86-64 backend_data.
2. Add generic, lay and non-lazy PLT layout configurations to x86-64
link_hash_table. Generic PLT layout includes the PLT entry templates,
information how to update the first instruction in PLT and PLT eh_frame
informaton, which are initialized in x86-64 setup_gnu_properties, based
on "-z bndplt" and target selection. PLT section alignment is also set
to PLT entry size for non-NaCl target.
3. Remove elf_x86_64_create_dynamic_sections. create_dynamic_sections
isn't always called, but GOT relocations need GOT relocations. Instead,
create all x86-64 specific dynamic sections with alignment to their entry
size in x86-64 setup_gnu_properties, which initializes elf.dynobj, so
that x86-64 check_relocs can be simplified.
4. Rewrite elf_x86_64_get_synthetic_symtab to check PLT sections against
all dynamic relocations to support both lazy and non-lazy PLTs.
There is no change in PLT. The only externally visible change is the
improvement of synthetic PLT symbols for .plt.got.

Make import libraries relocatable objects
For ELF targets --out-implib currently generates an executable file
(e_type is ET_EXEC) despite the file being expected to be linked against
some other object file to make an executable later. It seems therefore
more sensible to make the import library a relocatable object file
(e_type set to ET_REL).
Incidentally, as dicted by requirement 8 of
"ARM v8-M Security Extensions: Requirements on Development Tools"
(document ARM-ECM-0359818) version 1.0, import libraries generated when
using --cmse-implib *must* be relocatable object file so this commit
also adds an assert there in case the type of ELF import library is
changed again in the future.

Rearrange gdb/configure.nat to make it simpler and less redundant
The previous commit introduced gdb/configure.nat, but it was just a
copy-and-past (with the necessary adjustments) from the files under
gdb/config/. We can do better than that.
Instead of using one big 'case' statement that matches the
${gdb_host_cpu} and then match each ${gdb_host}, it is possible to
remove a lof of redundancy by matching the most common ${gdb_host}'s
first, setting the common variables for each, and then proceed to
matching specific ${gdb_host}'s and ${gdb_host_cpu}'s. In other
words, reverse the order of the 'case's and take advantage of the fact
that a lot of parameters are the same for each host.

Introduce "gdb/configure.nat" (and delete "gdb/config/*/*.mh" files)
Due to my ongoing work to make it possible for gdbserver to start the
inferior using the shell, I had to share the fork_inferior function
under the "nat/" directory. In order to do that, I created a new file
and put the function there; however, this meant that I now had to
update some of the *.mh files (under "gdb/config") and add the new
file as a dependency to be built natively. Bleh...
After talking a bit to Pedro about this, the idea came up to write a
new "gdb/configure.nat" file, a la "gdb/configure.tgt", which would
concentrate all of the native settings for each host/system. I
decided to tackle this issue.
The patch is simple. All of the previous Makefile variables that were
being declared inside the *.mh files are now inside "gdb/Makefile.in",
and "gdb/configure" is responsible for AC_SUBST'ing them. The
definitions of these variables were put inside "gdb/configure.nat", so
now they're shell variables. For excerpts of Makefile code, one must
create a file under "gdb/config/${gdb_cpu_host}" and reference it on
the "nat_extra_makefile_frag" variable.
It should now be easier to update the native dependencies of hosts in
this single file.
This has been tested on x86_64 without regressions.

gdb: Disable -Werror for -Wmaybe-uninitialized
Newer GCCs are triggering false-positive -Wmaybe-uninitialized
warnings around code that uses gdb::optional:
https://sourceware.org/ml/gdb-patches/2017-05/msg00118.html
Using std::optional wouldn't help, it triggers the same warnings:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80635
Initializing the variables to quiet the warning would defeat the
purpose of gdb::optional. Making the optional ctor memset its storage
would be a pessimization. Wrapping gdb::optional's internals with
"#pragma GCC diagnostic push/ignored/pop" doesn't work, we'd have to
wrap uses of gdb::optional instead, which I think would get unwieldy
and ugly as we start using gdb::optional more and more.
The -Wmaybe-uninitialized warning is documented as producing false
positives (unlike -Wuninialized), so until we find a better
workaround, disable -Werror for this warning. You'll still see the
warning when building gdb, but it won't cause a build failure.

From [1] it looks like the reason the variable was made static to

it on every function return path:
https://sourceware.org/ml/gdb-patches/2005-03/msg00237.html
The easiest to fix that nowadays is to use a std::string.
I don't see a need to xstrdup the section name in the single-threaded

Fix PR21404 - assertion fail when calculating symbol size
Fix a host of problems related to adjustment of
symbol values and sizes when relaxing for avr.
1. Adjust symbol size first before adjusting symbol
value. Otherwise, a symbol whose value just got adjusted to the
relaxed address also ends up getting resized. See pr21404-1.s.
2. Reduce symbol sizes only if their span is below an
alignment boundary. Otherwise, the size gets decremented once when the
actual instruction is relaxed and padding bytes are added, and again
when the padding bytes are deleted (if padding ends up being unnecessary).
pr21404-2.s addresses that, and this bug is really the root cause of PR21404.
3. Adjust all symbol values before an alignment boundary.
Previous code did not adjust symbol values if they fell in the
would-be padded area, resulting in incorrect symbol values in some
cases (see pr21404-3.s).
4. Increase symbol sizes if alignment directives require so.
As pr21404-4.s shows
.global nonzero_sym
L1:
jmp L1
nonzero_sym:
nop
nop
.p2align 2
.size nonzero_sym, .-nonzero_sym
The two nops satisfy the 4 byte alignment at assembly time and
therefore the size of nonzero_sym is 4. Relaxation shortens
the 4 byte jmp to a 2 byte rjmp, and to satisfy 4 byte alignment
the code places 2 extra padding bytes after the nops, increasing
nonzero_sym's size by 2. This wasn't handled before.
If the assembly code does not have any align directives, then the
boundary is the section size, and symbol values and sizes == boundary
should also get adjusted. To handle that case, add a did_pad variable
and use that to determine whether it should use < boundary or <= boundary.
Also get rid of reloc_toaddr, which is now redundant. toaddr is now not
adjusted to handle the above case - the newly added
did_pad variable does the job.
pr21404-{5,6,7,8} are the same testcases written for local symbols, as
the code handles them slightly differently.

MIPS16/GAS: Relax 32-bit non-PIC PC-relative synthetic instructions
Implement the relaxation of MIPS16 PC-relative synthetic LA, DLA, LW and
LD instructions to an equivalent sequence of instructions produced where
the address operand requested is out of range, absolute or requires
linker relocation, for ABIs that use 32-bit addressing and non-PIC code.
The sequence generated uses the register specified for the destination
operand as a temporary and begins with LI to load the high 16-bit part
of the address, then continues with SLL by 16 bits to move that part
into place and finally completes with a suitable operation corresponding
to the synthetic instruction used, one of: 2-argument ADDIU, 2-argument
DADDIU, absolute LW, and absolute LD respectively, providing the low
16-bit part of the address. All instructions use the extended encoding.
As a special exception accept absolute addresses for relaxation even in
PIC code.
For example:
la $2, 0x12345678
produces code as:
li $2, 0x1234
sll $2, $2, 16
addiu $2, 0x5678
would.
Where linker relocation is required emit an R_MIPS16_HI16 relocation on
the initial LI instruction and an R_MIPS16_LO16 relocation on the final
operation.
For example (where `foo' is not local):
lw $3, foo
produces code as:
li $3, %hi(foo)
sll $3, $3, 16
lw $3, %lo(foo)($3)
would.
Emit assembly warnings as appropriate where this new relaxation triggers
in the `nomacro' mode or for an instruction manually placed in a branch
delay slot in the `noreorder' mode. Refrain from relaxation where an
explicit instruction size suffix has been used and in the `noautoextend'
mode.

MIPS16/GAS: Fix absolute references with PC-relative synthetic instructions
Complement commit
88a7ef168927 ("MIPS16/GAS: Restore unsupported

already reduced from absolute symbol references or created from literals

Python: Introduce gdb.Instruction class
This adds a generic instruction class to Python and has gdb.RecordInstruction
inherit from it.

Python: Move and rename gdb.BtraceFunction
Remove gdb.BtraceFunctionCall and replace by gdb.FunctionSegment. Additionally,
rename prev_segment and next_segment to prev and next.

Python: Introduce gdb.RecordGap class
As discussed here: https://sourceware.org/ml/gdb-patches/2017-04/msg00157.html
A gap is not an instruction and it should not pretend to be one.
gdb.Record.instruction_history is now a list of gdb.RecordInstruction and
gdb.RecordGap objects. This allows the user to deal with Gaps in the record
in a more sane way.
