Fix duplicate output section statement lookup

Tie output section statements to their associated output section via
output section userdata.  This allows us to avoid hash lookups which
are slower and fail when multiple output sections have the same name.

	* ldlang.h (lang_output_section_get): Define.
	* ldlang.c (lang_output_section_get): Likewise.
	(init_os): Set the output_section userdata to the output
	section statement.
	* emultempl/hppaelf.em: Use lang_output_section_get instead of
	lang_output_section_find where applicable.
	* emultempl/aarch64elf.em: Likewise.
	* emultempl/aix.em: Likewise.
	* emultempl/armelf.em: Likewise.

Allow self-assignment for absolute symbols defined in a linker script

Modifies ld machinery tracking linker script assignments to notice all
assignments, not just those symbols mentioned in DEFINED().

ld/
	PR ld/14962
	* ldlang.h (struct lang_definedness_hash_entry): Add by_object and
	by_script.  Make iteration a single bit field.
	(lang_track_definedness, lang_symbol_definition_iteration): Delete.
	(lang_symbol_defined): Declare.
	* ldlang.c (lang_statement_iteration): Expand comment a little.
	(lang_init <lang_definedness_table>): Make it bigger.
	(lang_track_definedness, lang_symbol_definition): Delete.
	(lang_definedness_newfunc): Update.
	(lang_symbol_defined): New function.
	(lang_update_definedness): Create entries here.  Do track whether
	script definition of symbol is valid, even when also defined in
	an object file.
	* ldexp.c (fold_name <DEFINED>): Update.
	(fold_name <NAME>): Allow self-assignment for absolute symbols
	defined in a linker script.
ld/testsuite/

	* ld-scripts/expr.exp: Run it.
gdb: xtensa: fix linux ptrace includes

Currently, xtensa code using the Linux ptrace interface only include
sys/ptrace.h.  This file comes from the C library (glibc and uClibc,
at least), and includes a declaration of the ptrace() functions, along
with some cross architecture constants that are mostly copied from the
file located at include/uapi/linux/ptrace.h in recent Linux kernels.

For xtensa specific constants like PTRACE_GETXTREGS and
PTRACE_SETXTREGS the asm/ptrace.h include from the Linux kernel UAPI
is needed.  The code in gdbserver xtensa specific part doesn't call
ptrace() directly, so we can remove the unneeded sys/ptrace.h include.
The gdb xtensa specific code needs both headers, since it calls
ptrace().

gdb/
	* xtensa-linux-nat.c: Include asm/ptrace.h.

gdb/gdbserver/
	* linux-xtensa-low.c: Include asm/ptrace.h instead of
	sys/ptrace.h.
Add a testcase for PR ld/2404

PR ld/2404 was fixed without a testcase.  This patch to add one.

	PR ld/2404
	* ld-elf/pr2404.out: New file.
	* ld-elf/pr2404a.c: Likewise.
	* ld-elf/pr2404b.c: Likewise.

	* ld-elf/shared.exp (build_tests): Build libpr2404a.so and
	libpr2404b.a.
	(run_tests): Run pr2404.
convert flags to bitfields

This changes various flags struct cmd_list_element into bitfields.  In
general I think bitfields are cleaner than flag words, at least in a
case like this where there is no need to pass the flags around
independently of the enclosing struct.

2014-01-20  Tom Tromey  <tromey@redhat.com>

	* cli/cli-decode.c (add_cmd, deprecate_cmd, add_alias_cmd)
	(add_setshow_cmd_full, delete_cmd, lookup_cmd_1)
	(deprecated_cmd_warning, complete_on_cmdlist): Update.
	* cli/cli-decode.h (CMD_DEPRECATED, DEPRECATED_WARN_USER)
	(MALLOCED_REPLACEMENT, DOC_ALLOCATED): Remove.
	(struct cmd_list_element) <flags>: Remove.
	<cmd_deprecated, deprecated_warn_user, malloced_replacement,
	doc_allocated>: New fields.
	<hook_in, allow_unknown, abbrev_flag, type, var_type>: Now
	bitfields.
	* maint.c (maintenance_do_deprecate): Update.
	* top.c (execute_command): Update.
better packing for command struct

This moves all the bitfields in struct cmd_list_element to be closer
together.  This packs the structure somewhat better.  On a 64 bit
machine, this simple rearrangement saves around 50k at startup.

2014-01-20  Tom Tromey  <tromey@redhat.com>

	* cli/cli-decode.h (struct cmd_list_element): Move all bitfields
	together.
[AArch64] Define LP64 LE loader name.
[AArch64] Define LP64 BE linker name.

Don't check shared/export_dynamic/ref_dynamic for type mismatch

There is nothing linker can do when a type mismatched default definition
are made dynamic by info->shared, info->export_dynamic or h->ref_dynamic.
But we do want to avoid exporting it when building PIE.  Let's remove
those checks.

bfd/

	PR ld/2404
	* elflink.c (_bfd_elf_merge_symbol): Don't check info->shared,
	info->export_dynamic, nor !h->ref_dynamic for type mismatch when
	adding the default version.

ld/testsuite/

	PR ld/2404
	* ld-elf/shared.exp: Add a PIE test for PR ld/2404.
