AMD64 spec and Intel64 spec differ in direct unconditional branches in
64-bit mode. AMD64 supports direct unconditional branches with 16-bit
offset via the data size prefix, which truncates RIP to 16 bits, while
the data size prefix is ignored by Intel64.
This patch adds -mamd64/-mintel64 option to x86-64 assembler and
-Mamd64/-Mintel64 option to x86-64 disassembler. The most permissive
ISA, which is AMD64, is the default.
GDB can add an option, similar to
(gdb) help set disassembly-flavor
Set the disassembly flavor.
The valid values are "att" and "intel", and the default value is "att".
to select which ISA to disassemble.

This patch adds -mshared option to x86 ELF assembler. By default,
assembler will optimize out non-PLT relocations against defined non-weak
global branch targets with default visibility. The -mshared option tells
the assembler to generate code which may go into a shared library
where all non-weak global branch targets with default visibility can
be preempted. The resulting code is slightly bigger. This option
only affects the handling of branch instructions.

On ELF target, the assembler normally generates code which can go into a
shared library where non-weak symbols can be preempted. The -mno-shared
option tells the assembler to generate code not for a shared library,
where non-weak symbols won't be preempted. The resulting code is slightly
smaller. This option mainly affects the handling of branch instructions.

This x86 assembler patch:
https://sourceware.org/ml/binutils/2001-11/msg00344.html
generates a .note section for .arch directive so that GDB can tell which
architecture an i386 binary belongs:
https://sourceware.org/ml/binutils/2001-11/msg00271.html
However, x86 assembly code can have any instructions. A .note section
doesn't help. This patch removes it.

Certain conversion operations as well as vfpclassp{d,s} are ambiguous
when the input operand is in memory. That ambiguity, however, doesn't
apply when using broadcasts (the destination operand size can be

This patch adds --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi}
options to gas and objcopy for ELF files. They control how DWARF debug
sections are compressed. --compress-debug-sections=none is equivalent to
--nocompress-debug-sections. --compress-debug-sections=zlib and
--compress-debug-sections=zlib-gnu are equivalent to
--compress-debug-sections. --compress-debug-sections=zlib-gabi compresses
DWARF debug sections with SHF_COMPRESSED from the ELF ABI. No linker
changes are required to support SHF_COMPRESSED.

The write.c change is to make gas report an error if reg_section
symbols should leak in future. The tc-i386.c change is the real fix.
Note that the error isn't the most helpful, "redefined symbol cannot
be used on reloc", but I'm not inclined to improve what is really an
internal gas error. reg_section symbols shouldn't leak..

A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables. That's OK, but not best
practice. tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants. This patch fixes both of these warts.

* config/tc-i386.c (check_VecOperands): Remove regzmm from AVX2
gather assert.

AVX512 gather instructions shouldn't accept the same register for both
destination and index.
