This reverts most of 06803313754, 2005-07-05 Dmitry V. Levin change
adding a check that section size doesn't exceed file size. As we've
seen recently with mmo tests, decoded section size can easily exceed
file size with formats that encode section data.
I've also changed "strings" to use bfd_malloc_and_get_section, so that
"strings" won't die on a malloc failure. I think it's better to
continue on looking at other sections after failing to dump a section
with fuzzed size.
The testcases at https://bugzilla.altlinux.org/show_bug.cgi?id=5871
on a 32-bit host now produce
$ strings -d --target=a.out-i386 /tmp/bfdkiller.dat
strings: error: /tmp/bfdkiller.dat(.text) is too large (0xffffffff bytes)
strings: /tmp/bfdkiller.dat: Reading section .text failed: Memory exhausted
strings: /tmp/bfdkiller.dat: Reading section .data failed: File truncated

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.

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.

the MIPS16e2 ASE as per documentation, including in particular:
1. Support for implementation-specific interAptiv MR2 COPYW and UCOPYW
MIPS16e2 instructions[1], for assembly and disassembly,
2. Support for implementation-specific interAptiv MR2 SAVE and RESTORE
regular MIPS instructions[2], for assembly and disassembly,
3. ELF binary file annotation for the interAptiv MR2 MIPS architecture
extension.
4. Support for interAptiv MR2 architecture selection for assembly, in
the form of the `-march=interaptiv-mr2' command-line option and its
corresponding `arch=interaptiv-mr2' setting for the `.set' and
`.module' pseudo-ops.
5. Support for interAptiv MR2 architecture selection for disassembly,
in the form of the `mips:interaptiv-mr2' target architecture, for

=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.
=== Patch description ===
Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.
Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.
