* coffread.c, dbxread.c, elfread.c, mipsread.c somread.c:
Adjust the struct sym_fns object accordingly by setting
the new field to NULL.
* xcoffread.c (aix_process_linenos): Make static.
(xcoff_sym_fns): Set new field to aix_process_linenos.
* buildsym.c (end_symtab): Replace call to PROCESS_LINENUMBER_HOOK
by call to new the new sym_fns sym_read_linetable function.
* config/powerpc/aix.mt (DEPRECATED_TM_FILE): Delete.
* config/rs6000/tm-rs6000.h: Delete.
(BFD32_LIBS_CFILES): Add arange-set.c.
(SOURCE_HFILES): Add arange-set.h
(dwarf2.lo): Add dependency upon arange-set.h.
(arange-set.lo): New target.
* Makefile.in: Regenerate.
* arange-set.c: New file.
* arange-set.h: New file.
* dwarf2.c: Include arange-set.h.
(struct dwarf2_debug) Add new fields comp_unit_count and comp_unit_arange_set.
(struct comp_unit) Replace field arange with a new field arange_set.
(dwarf2_arange_set_allocate, dwarf2_arange_set_deallocate,
(dwarf2_combine_arange_value, dwarf2_arange_set_new,
(dwarf2_arange_set_with_value_new, dwarf2_comp_unit_arange_add): New
functions to utilize arange set in dwarf2.c.
(arange_add): Formatting change for a line longer than 80 characters.
(decode_line_info): Replace call target arange_add with
(dwarf2_comp_unit_arange_add.
(read_rangelist_insert_arange_list,
(read_rangelist_comp_unit_arange_add): New functions used as callbacks
for read_rangelist.
(read_rangelist): Change interface to accept a callback and data to
allow caller to select the action peformed on a new range list read.
(scan_unit_for_symbols): Use new interface of read_rangelist.
(parse_comp_unit): Create an arange set for each new comp unit. Use new
interface of read_rangelist. Replace call to arange_add with that to
dwarf2_comp_unit_arange_add.
(comp_unit_contains_address): Replace sequential search with a call to
arange_set_lookup_address, which can handles large set efficiently.
(stash_copy_local_aranges, stash_maybe_enable_arange_set,
(stash_find_nearest_line_fast): New functions maintaining and using a
valued global arange set for all compilation units to speed up
bfd_dwarf2_find_nearest_line.
(find_line): Use global arange set. Replace sequential search over all
compilation units with a call to stash_find_nearest_line_fast. Add
book keeping to count number of compilation units. Replace empty
arange list test with a call to arange_set_empty_p.
specific SOM sections for stabs if the regular ones are not found.
* som.h (struct somdata): Add a line_info field, to be used by som_find_nearest_line.
* som.c (som_find_nearest_line): Implement using the bfd stabs function above.
* configure, config.in: Regenerate.
* maint.c (TEXTEND): Only define if either _etext or etext
are available.
Disable the profiling functionality if TEXTEND is not defined.
(inf_ttrace_delete_dying_threads_callback): New function.
(inf_ttrace_resume): After resuming the execution, iterate over
the dying threads to delete them for the thread list.
(inf_ttrace_wait): on TTEVT_LWP_EXIT and TTEVT_LWP_TERMINATE,
mark the corresponding thread as dying instead of removing it
from the thread list.
(inf_ttrace_thread_alive): return 0 for dying threads.
