21c40443ce binutils objcopy test tidy
The main aim of this patch is to perform more objcopy tests when we
can build executables but not run them.  ie. non-native with cross
compiler available.

	* binutils-all/objcopy.exp: Delete trailing whitespace.  Use
	"string equal" rather than "string match" when making simple
	string comparisons.  Revert 2008-07-08 host_triplet checks.
	Perform non-run tests when we can build executable.
	(strip_executable, strip_executable_with_saving_a_symbol): Move
	run test later.  Take extra param on whether to perform run test.
	Update callers.
	(keep_debug_symbols_and_test_copy): Delete unused vars.

7b19bec22f objcopy --extract-symbol testcase
Run the test for more than just ELF.  Shows that objcopy --extract-symbol
isn't working on PE, mips, mmix and some aout targets.

	* ld-elf/extract-symbol-1.s,
	* ld-elf/extract-symbol-1.ld,
	* ld-elf/extract-symbol-1sec.d,

edbbff4a22 gdb: Avoid unneeded calls to parse_frame_specification.
Within the stack command there are a couple of places where fixed
strings are passed into functions that are really intended for
processing user input.  These fixed strings are then processed and the
result returned.

Given that the input strings in these cases are fixed, and are always
"0", then the result will always be the same, the current frame.  By
switching to using get_current_frame instead the code can be simplified,
and the intention of the code is clearer.

gdb/ChangeLog:

	* stack.c (parse_frame_specification): Delete.
	(parse_frame_specification_1): Rename to
	parse_frame_specification.
	(frame_info): Use parse_frame_specification.

9d622bda56 gdb: Fix bug with dbx style func command.
The func command, available when starting gdb in dbx mode, is supposed
to take a function name and locate the frame for that function in the

arguments within the worker function.  Fixed in this commit.

	string.

fc58fa65d4 gdb/doc: Restructure frame command documentation.
The 'frame' command is documented in two places.  The 'select-frame'
command is only mentioned in one of these places.

Of the two places, having the description of 'frame' and 'select-frame'
in the section 'Selecting a Frame' seems like the most obvious choice,
which is where things like 'up' and 'down' are also documented.

This commit moves the documentation of 'frame' and 'select-frame' into
the 'Selecting a Frame' section, and removes the duplicate documentation
of the 'frame' command.

At the same time I have reordered the sections in the 'Examining the
Stack' chapter, moving the discussion of frame filters to the end of the
chapter; it feels odd that we talk about frame filters before such basic
things like navigating the stack, or examining stack frames in general.

gdb/doc/ChangeLog:

	* gdb.texinfo (Frames): Remove 'frame' and 'select-frame'
	description.
	(Frame Filter Management): Move to later in the 'Examining the
	Stack' chapter.

b6542f81d0 Support displaced stepping in aarch64-linux
This patch is to support displaced stepping in aarch64-linux.  A
visitor is implemented for displaced stepping, and used to record
information to fixup pc after displaced stepping if needed.  Some
emit_* functions are converted to macros, and moved to
arch/aarch64-insn.{c,h} so that they can be shared.

0badd99faf Use visitor in aarch64_relocate_instruction
Nowadays, the instruction decodings and handling are mixed together
inside aarch64_relocate_instruction.  The patch decouples instruction
decoding and instruction handling by using visitor pattern.  That is,
aarch64_relocate_instruction decode instructions and visit each
instruction by different visitor methods.  Each visitor defines the
concrete things to different instructions.  Fast tracepoint instruction
relocation and displaced stepping can define their own visitors,
sub-class of struct aarch64_insn_data.

This patch is to move target_read_uint32 out of
aarch64_relocate_instruction and pass INSN to
aarch64_relocate_instruction, so that it is cleaner, only decode
instructions.

2520f728b7 Forward VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT
Assume foo_array is a pointer to a C structure. GDB must evaluate the
following expression properly, but it does not currently:

    (gdb) print 1 && &foo_array[1].a
    Attempt to take address of value not located in memory.

The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_STRUCT operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned
value.

This patch fixes STRUCTOP_STRUCT handling so that the VALUE_LVAL
attribute for the returned value is properly initialized.  After this
change, the above session becomes:

    (gdb) print 1 && &foo_array[1].a
    $1 = 1

gdb/ChangeLog:

	* eval.c (evaluate_subexp_standard) <STRUCTOP_STRUCT>: If
	EVAL_AVOID_SIDE_EFFECTS mode, forward the VALUE_LVAL attribute
	to the returned value.

gdb/testsuite/ChangeLog:

	* gdb.base/nested-addr.c: New file.
	* gdb.base/nested-addr.exp: New testcase.

Tested on x86_64-linux, no regression.

431ff0756a avr: Fix bugs in org/align tracking.
This commit fixes a few issues in the mechanism for passing information
about ".org" and ".align" directives from the assembler to the linker,
used by the avr target.

In the original commit fdd410ac7a, there
were some mistakes when writing out information about ".align"
directives:
  - An align with fill does not write out its information correctly, the
    fill data overwrites the alignment data.
  - Each alignment directive is recorded at the location where the
    previous alignment directive should be recorded, the first alignment
    directive is discarded.

In commit 137c83d69f, the data produced by
objdump is not correct:
   - It's miss-aligned due to a missing whitespace.
   - The fill data for align with fill records is not displayed
     correctly.

All of the above issues are addressed in this commit, and the test is
improved to cover these cases.

binutils/ChangeLog:

	* od-elf32_avr.c (elf32_avr_dump_avr_prop): Fix printing of align
	specific data, fix formatting for align and org data.

gas/ChangeLog:

	* config/tc-avr.c (avr_output_property_record): Fix overwrite bug
	for align and fill records.
	(avr_handle_align): Record fill information for align frags.
	(create_record_for_frag): Add next frag assertion, use correct
	address for align records.

gas/testsuite/ChangeLog:

	* gas/avr/avr-prop-1.s: Use fill in some cases.
	* gas/avr/avr-prop-1.d: Update expected results.
