(extra_augmentation_data_bytes): Likewise. Use an FDE's own
add_augmentation_size field, rather than referring to the CIE.

make_relative field; set the eh_cie_fde field directly.
Update setting of add_fde_encoding and per_encoding_relative.
Copy make_relative and add_augmentation_size from the CIE
to the FDE.

againts the section's FDEs. Don't mark the bfd's elf_eh_frame_section.

* elf-eh-frame.c (_bfd_elf_begin_eh_frame_parsing): New function.
(_bfd_elf_parse_eh_frame): New function, split out from
_bfd_elf_discard_section_eh_frame. Make a first pass through the
buffer to calculate the number of entries and CIEs. Allocate memory
for them before the main loop. Replace current extended cie
representation with a pair of pointers, one to the local eh_cie_fde
and one to the full struct cie. Allocate a separate array of struct
cies if not merging. Merge CIEs during the main loop and set up each
u.cie.merged field. Point an FDE's cie_inf field directly at the
local CIE. Initially assume that all entries should be removed.

already been parsed. Use a separate pass to mark entries that
need to be kept. Use the u.cie.merged field to track a CIE's
group representative.

before _bfd_elf_discard_section_eh_frame. Wrap loop with calls to
_bfd_elf_begin_eh_frame_parsing and _bfd_elf_end_eh_frame_parsing.

field. Use bitfields for fde_encoding, lsda_encoding and lsda_offset.

accesses after the above change.

and fini_reloc_cookie_for_section.
* gdb.h (gdb_breakpoint): Add parameter pending.
* breakpoint.c (gdb_breakpoint): Add parameter pending.
* mi/mi-cmd-break.c (mi_break_insert): Change
comment to refer to manual. Add support for
the -f flag, for pending breakpoint.
from break_command_1. New parameters COND_STRING, THREAD
PARSE_CONDITITION_AND_THREAD and PENDING_BREAK_SUPPORT.
The previous FLAG parameter split into TEMPFLAG and
HARDWAREFLAG.
When PARSE_CONDITION_AND_THREAD is not set, duplicate
the passed condition string.
(struct captured_breakpoint_args): Remove
(do_captured_breakpoint): Remove.
(break_command_1): Relay to break_command_really.
(gdb_breakpoint): Relay to break_command_really.
* config/tc-xtensa.c (xg_symbolic_immeds_fit): Relax for weak
references but not weak definitions.

* gas/xtensa/all.exp: Run new weak-call test.
* gas/xtensa/weak-call.d: New.
* gas/xtensa/weak-call.s: New.
(dwarf2_add_field): Use it and attr_form_is_section_offset to
recognize DW_AT_data_member_location attributes. Use
dwarf2_get_attr_constant_value when the attribute is a constant.
* dwarf2read.c (attr_form_is_section_offset): New function.
(dwarf_add_member_fn, read_common_block, read_partial_die)
(dwarf2_symbol_mark_computed): Use it, instead of writing it out.
