8d1015a887 Move struc-symbol.h to symbols.c 
This file was never supposed to be widely used.  The fact that it has
found its way into many gas files led to bugs, typically when code
expecting a symbolS* to point at a struct symbol is presented with a
struct local_symbol.  Also, commit 158184ac9e changed these structs in
2012 but didn't catch all places where symbol bsym was being used to
test for a local_symbol.

	* Makefile.am (HFILES): Delete struc-symbol.h.
	* doc/internals.texi: Delete struc-symbol.h reference and out
	of date local symbol description.

62a02d25b6 Add .nop assembler directive 
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits
SIZE bytes filled with no-op instructions.  SIZE is absolute expression.
The optional CONTROL byte controls how no-op instructions should be
generated.  If the comma and @var{control} are omitted, CONTROL is
assumed to be zero.

For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size
limit of a single no-op instruction.  The valid values of CONTROL byte
are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode,
between 0 and 11 for 64-bit mode.  When 0 is used, the no-op size limit
is set to the maximum supported size.

2 new relax states, rs_space_nop and rs_fill_nop, are added to enum
_relax_state, which are similar to rs_space and rs_fill, respectively,
but they fill with no-op instructions, instead of a single byte.  A
target backend must override the default md_generate_nops to generate
proper no-op instructions.  Otherwise, an error of unimplemented .nop
directive will be issued whenever .nop directive is used.

9875b36538 GAS: Fix bogus "attempt to move .org backwards" relaxation errors 
Fix a commit 6afe8e98a6 ("internal error for backwards .org"),
<https://www.sourceware.org/ml/binutils/2008-06/msg00212.html>,
GAS regression that caused legitimate code to fail assembly with an
"attempt to move .org backwards" error.

For example with the `mips-linux' target we get:

$ cat org.s
	.set	mips16
	la	$2, foo
	.org	0x1000
	.align	2
foo:
	.half	0
$ as -o org.o org.s
org.s: Assembler messages:
org.s:3: Error: attempt to move .org backwards
$

where the location pointer is obviously not moved backwards with `.org'.

The cause is positive `stretch' in relaxation due to a PC-relative ADDIU
instruction (produced from the LA macro used) getting expanded from 2 to
4 bytes as `foo' is noticed to be out of range for the short encoding.
This in turn triggers logic in `relax_segment' which concludes in the
processing of an `rs_org' frag produced that the location pointer is
moved backwards while in fact only the amount to space forward to the
location requested has shrunk, resulting in a negative growth of the
frag.

Correct the bad logic then and instead verify that the fixed part of an
`rs_org' frag has not overrun the location requested, as per the comment
already included with the error message:

/* Growth may be negative, but variable part of frag
   cannot have fewer than 0 chars.  That is, we can't
   .org backwards.  */

which accurately describes the regression scenario.  Move the comment
ahead the conditional noted, for clarity.

Add generic and MIPS test cases for the `.org' pseudo-op, including the
test case discussed though not integrated with the offending commit in
particular, adjusted to work across all targets.

	part of the frag has overrun the location requested.

93a24ba79b PR gas/20312: Do not pad sections to alignment on failed assembly 
Correct a regression from commit 85024cd8bc ("Run write_object_file
after errors") causing unsuccessful assembly, which may be due to any
reason, such as supplying a valid source like this:

	.text
	.byte	0
	.err

to terminate with an assertion failure like:

test.s: Assembler messages:
test.s:3: Error: .err encountered
../as-new: BFD (GNU Binutils) 2.24.51.20140628 internal error, aborting at .../gas/write.c line 608 in size_seg
../as-new: Please report this bug.

on targets whose default text section alignment is above 0, typically
RISC machines.

This is due to an attempt to set last text section's frag alignment to
0, requested from `subsegs_finish_section' where `frag_align_code
(alignment, 0)' is called with `alignment' set to 0 rather than the
section alignment if `had_errors' has returned true.  The call to
`subsegs_finish_section' is made from `subsegs_finish' from
`write_object_file' at unsuccessful completion, which previously wasn't
made.

Always set last section's frag alignment from the section alignment
then, forcing no section padding instead if completing unsuccessfully,
so that in that case alignment padding is still suppressed from any
listing generated, fixing assertion failures for these targets:

6d44f09a76 GAS: Fix `abort' expansion in write.c 
Remove an internal diagnostic regression introduced with the inclusion of
"libbfd.h" from write.c, added with:

commit e7ff5c732e
Author: Alan Modra <amodra@gmail.com>
Date:   Fri Feb 16 03:40:17 2007 +0000

That change made "libbfd.h" override the `abort' definition provided by
"as.h" earlier on, making the message produced by any calls reached from
write.c, which is a part of the GAS proper, look like they came from
BFD, e.g.:

.../gas/testsuite/gas/elf/type.s: Assembler messages:
.../gas/testsuite/gas/elf/type.s:30: Error: symbol type "gnu_unique_object" is supported only by GNU targets
../as-new: BFD (GNU Binutils) 2.26.51.20160628 internal error, aborting at .../gas/write.c:608 in size_seg

../as-new: Please report this bug.

vs:

.../gas/testsuite/gas/elf/type.s: Assembler messages:
.../gas/testsuite/gas/elf/type.s:30: Error: symbol type "gnu_unique_object" is supported only by GNU targets
.../gas/testsuite/gas/elf/type.s: Internal error, aborting at .../gas/write.c:602 in size_seg
Please report this bug.

With the removal of "libbfd.h" restore the latter message format.

One of the tic54x testcases looks for a section alignment of 1.  After

of 0 is treated as an alignment of 1, there is no reason to not apply

b8871f357f Properly implement STT_COMMON 
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build.  Instead,
this patch removes it from BFD.  It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.

A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.

Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

151411f8af Add SHF_COMPRESSED support to gas and objcopy 
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.

a841bdf5d3 Fix PR17493, attempted output of *GAS `reg' section* symbol 
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..

85024cd8bc Run write_object_file after errors 
This is to fix unitialised memory access when printing listings.
Many targets don't initialise parts of insn frags or data frags that
have fixups, relying on md_apply_fix to finalise the frag.  Which is
fine normally, but means we need to run write_object_file after
errors, for listings.  Otherwise MALLOC_PERTURB_=1 causes errors like:
x86_64-linux  +FAIL: i386 mpx-inval-1
x86_64-linux  +FAIL: i386 inval-equ-1
x86_64-linux  +FAIL: i386 x86-64-mpx-inval-1

Running write_object_file after errors requires some tweaking to the
testsuite, since we then get extra errors reported from md_apply_fix.

62ebcb5cbe gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEW 
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.
