Fix `set architecture' and `set endian' command disassembly regressions
from commit 39503f82427e ("Delegate opcodes to select disassembler in
GDB"), and commit 003ca0fd2286 ("Refactor disassembler selection"), as
well as a MIPS compressed ISA disassembly target regression from commit
6394c606997f ("Don't use print_insn_XXX in GDB"), which caused assertion
failures to trigger.
For example with the `mips-linux-gnu' target we get:
$ cat main.c
int
main (void)
{
return 0;
}
$ gcc -mips32r2 -O2 main.c -o main
$ gcc -mips16 -mips32r2 -O2 main.c -o main16

When elf section size is beyond unsigned int max value, objdump fails
to disassemble from that section. Ex on PowerPC,
$ objdump -h /proc/kcore
Idx Name Size VMA
4 load2 100000000 c000000000000000
Here, size of load2 section is 0x100000000. Also note that, 0xc00....
address range is kernel space for PowerPC. Now let's try to disassemble
do_sys_open() using /proc/kcore.
$ cat /proc/kallsyms | grep -A1 -w do_sys_open
c00000000036c000 T do_sys_open
c00000000036c2d0 T SyS_open
Before patch:
$ objdump -d --start-address=0xc00000000036c000 --stop-address=0xc00000000036c2d0 /proc/kcore
/proc/kcore: file format elf64-powerpcle
Disassembly of section load2:
c00000000036c000 <load2+0x36c000>:
c00000000036c000: Address 0xc00000000036c000 is out of bounds.
Fix this by changing type of 'buffer_length' from unsigned int to
size_t. After patch:
$ objdump -d --start-address=0xc00000000036c000 --stop-address=0xc00000000036c2d0 /proc/kcore
/proc/kcore: file format elf64-powerpcle
Disassembly of section load2:
c00000000036c000 <load2+0x36c000>:
c00000000036c000: fc 00 4c 3c addis r2,r12,252
c00000000036c004: 00 53 42 38 addi r2,r2,21248
c00000000036c008: a6 02 08 7c mflr r0

* dis-asm.h (struct disassemble_info): Change type of buffer_length
field to size_t.
opcodes/

The instructions are not documented in the Intel SDM but are documented
in the AMD APM as an alias to the group 2, ModRM.reg == 4 variant.
Both AMD and Intel CPUs execute the C[0-1] and D[0-3] instructions as
expected, i.e., like the /4 aliases:
#include <stdio.h>
int main(void)
{
int a = 2;
printf ("a before: %d\n", a);
asm volatile(".byte 0xd0,0xf0" /* SHL %al */
: "+a" (a));
printf("a after : %d\n", a);
return 0;
}
$ ./a.out
a before: 2
a after : 4

Correct a commit 7d64c587c15f ("Add support for the MIPS eXtended
Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization
ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.
For example this source assembles successfully as shown below:
$ cat xpa.s
mfhc0 $2, $1
$ as -32 -mips32 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1'
$ as -32 -mips32r2 -o xpa.o xpa.s
$ objdump -d xpa.o
xpa.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <.text>:
0: 40420800 mfhc0 v0,c0_random
...
$
To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table. Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).
Now the same source is correctly rejected unless the `-mxpa' option is
also used:
$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1'
$ as -32 -mips32r2 -mxpa -o xpa.o xpa.s
$
Add test cases for XPA base and XPA Virtualization ASE instructions.

Correct a commit 25499ac7ee92 ("MIPS16e2: Add MIPS16e2 ASE support")
disassembler bug with the handling of the ASE_MIPS16E2_MT combination
ASE flag, where the calculation uses MIPS ABI Flags directly rather than
calculated internal ASE flags. Consequently code does not correctly set
the ASE_MIPS16E2_MT flag when the MIPS16e2 ASE flag and the MT ASE flag
come from different sources, i.e. one from the BFD chosen and the other
one from MIPS ABI Flags.
Fix this by using internal ASE_MT and ASE_MIPS16E2 flags in a separate
subsequent step, factored out to a dedicated function for use with
future combination ASE flags. Adjust the `mips16e2@mips16e2-mt-sub.d'
test case accordingly, where the MT flag comes from the BFD selected for
the disassembler and the MIPS16e2 flag comes from the ELF binary itself.

This patch updates arc-dis.c:parse_disassembler_options to use a macro
FOR_EACH_DISASSEMBLER_OPTION, which has been introduced in [1], instead of a

There is a bug in handling of cpu=... disassembler option in case there are
other options after it, for example, `cpu=EM,dsp'. In this case `EM,dsp' is
treated as an option value, and strcasecmp reports is as non-equal to "EM".
This is fixed by using disassembler_options_cmp function, which compares string
treating `,' the same way as `\0'.
This function also solves a problem with option order in parse_option.
Previously, if several option had same prefix (e.g. fpud, fpuda), then the
longer one should have been compared first, otherwise when longer option is
passed it would be treated as a short one, because
CONST_STRNEQ ("fpud", "fpuda")
would be true. The order of options was correct for ARC, so there were no
bugs per se, but with disassembler_option_cmp there is no risk of such a bug
being introduced in the future.

This is a follow-up to
[PATCH 0/6] Unify the disassembler selection in gdb and objdump
https://sourceware.org/ml/binutils/2017-05/msg00192.html
that is, opcodes is able to select the right disassembler, so gdb
doesn't have to select them. Instead, gdb can just use
default_print_insn. As a result, these print_insn_XXX are not used
out of opcodes, so this patch also moves their declarations from
include/dis-asm.h to opcodes/disassemble.h. With this change,
GDB doesn't use any print_insn_XXX directly any more.

Currently print_insn_arc relies on BFD mach and ELF private headers to
distinguish between various ARC architectures. Sometimes those values are not
correct or available, mainly in the case of debugging targets without and ELF
file available. Changing a BFD mach is not a problem for the debugger, because
this is a generic BFD field, and GDB, for example, already sets it according to
information provided in XML target description or specified via GDB 'set arch'
command. However, things are more complicated for ELF private headers, since
it requires existing of an actual ELF file. To workaround this problem this
patch allows CPU model to be specified via disassemble info options. If CPU is
specified in options, then it will take a higher precedence than whatever might
be specified in ELF file.
This is mostly needed for ARC EM and ARC HS, because they have the same
"architecture" (mach) ARCv2 and differ in their private ELF headers. Other ARC
architectures can be distinguished between each other purely via "mach" field.
Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid
ARC CPU name as supported by GAS. Note that this creates a seeming redundancy
with objdump -m/--architecture option, however -mEM and -mHS still result in
"ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual
effect on disassembler.

This patch changes rl78 to let disassble.c:disassembler select
disassembler. rl78_get_disassembler doesn't handle the case
that abfd is NULL, so this patch also fix it.

Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only. However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd. This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).
There isn't any functionality change.

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.
Parts of this change by Matthew Fortune and Andrew Bennett.
