(ctrl_table): Add "flags" keyword and some comments.
(flag_table): Convert to uppercase.
(get_flags_operand): Be case insensitive.
(get_interrupt_operand): Be case insensitive. Support notation
where the inperrupt arguments are separated by commas.
(get_operands): Check whether get_flags_operand consumed all
arguments. Return failure if get_ctrl_operand didn't recognize a
valid control register.
(get_specific): Add case CLASS_CTRL: Test for valid control
register for ldctlb opcode.
(build_bytes): Check for valid control registers.
(s_comm): Split out code to..
(s_comm_internal): ..here. Tidy error returns. Rearrange so that
"name" from input line may be used in more places. Merge code
testing for valid size from elf_common. Merge code from
s_lcomm_internal. Call comm_parse_extra.
(bss_alloc): New function, split out of s_lcomm_internal and
elf_common.
(parse_align): Likewise.
(s_lcomm_internal): Rewrite.
(s_lcomm, s_lcomm_bytes): Use s_comm_internal.
* read.h (bss_alloc, parse_align, s_comm_internal): Declare.
* config/obj-elf.c (elf_common): Split out code to..
(elf_common_parse): ..here. Remove code common to s_comm_internal,
parse_align and bss_alloc. Rearrange and Tidy.
* config/tc-alpha.h (TC_IMPLICIT_LCOMM_ALIGNMENT): Define.
* libunwind-frame.c (unw_find_dyn_list_p): Replace most arguments
with a single unw_dyn_info_t pointer.
(libunwind_find_dyn_list): Likewise.
* libunwind-frame.h: Likewise.
* ia64-tdep.c (ia64_find_unwind_table): Switch to using
UNW_INFO_FORMAT_REMOTE_TABLE so we can avoid having to read in the
entire unwind-table at once. Support for this table format has
been added to libunwind v0.95.
(ia64_find_proc_info_x): Adjust for remote-unwind-table changes.
(ia64_get_dyn_info_list): Adjust for interface change for
libunwind_find_dyn_list().
* breakpoint.c (breakpoint_enabled): New function to test whether
breakpoint is active and enabled.
(insert_bp_location, insert_breakpoints): Call new function to test
for enabled breakpoint.
(remove_breakpoint, breakpoint_here_p, breakpoint_thread_match)
(bpstat_should_step, bpstat_have_active_hw_watchpoints)
(disable_breakpoints_in_shlibs, hw_watchpoint_used_count)
(disable_watchpoints_before_interactive_call_start)
(breakpoint_re_set_one): Ditto.
(bpstat_stop_status): Use new function and simplify test.
