* xcoffsolib.c (xcoff_solib_address): Renamed from
pc_load_segment_name. Return NULL if address is not in a shared
library. Cleanup shared library name construction, using xasprintf.
Format shared library member names consistent with format in exec.c.
(solib_info): Format shared library member names consistent with
format in exec.c.
* config/rs6000/nm-rs6000.h: Replace PC_LOAD_SEGMENT with PC_SOLIB,
using xcoff_solib_address for PC_SOLIB definition.

work-around for a missing Sun header file in solaris for sparc64.
issue a message about truncation unless it exceeds the length of
an address, not the length of a pointer. This is because what the
user gives us is an address, not a pointer, and we will ultimately
convert it (via ADDRESS_TO_POINTER) to a pointer, not truncate it
to a pointer. This allows things like "print *(int *)0x01000234"
to work without generating a misleading message on a target having
two byte pointers and four byte addresses.
* sh-tdep.c: Update copyright.
(sh_extract_return_value): Rewrite.
(sh3e_sh4_extract_return_value): New function.
(sh_gdbarch_init): Initialize gdbarch_extract-return_value to new
version of the function for sh3e and sh4 CPUs.
* gdb.c++/ovldbreak.exp (take_gdb_out_of_choice_menu): New proc
to call when tests fail. It takes gdb out of the overloaded
function choice menu back to the main prompt, so that the test
program stays synchronized.
(set_bp_overloaded): New proc to collect all the common
code for setting a breakpoint on an overloaded name. Calls
take_gdb_out_of_choice_menu when needed.
(menu_overload1arg): New variable to collect the repeated
instances of the expected menu for an overloaded name. Change
the regular expression to handle changes in g++ type encoding:
"void" can be either "void" or "", and "unsigned int" can be
either "unsigned int" or "unsigned".
(continue_to_bp_overloaded): Change regular expressions to handle
changes in g++ type encoding.
(no proc): Call take_gdb_out_of_choice_menu when needed.
Remove redundant calls to "info break". Accept either "canceled"
or "cancelled". Change regular expressions in "info break"
calls to handle changes in g++ type encoding. Give all tests
unique strings.

instead of calling ui_out_list_end directly, let do_cleanups
handle it.
Fix double parsing of filenames passed as command line arguments
to GDB (causes weird handling of escape characters).
Also, remove dependencies on the CLI from libgdb.

symbol_file_command().
* remote-es.c: Include "symfile.h".

* dcache.h (set_dcache_state): Removed declaration.
* dcache.c (set_dcache_state): Removed definition

variable "remotecache". Add comment describing the interaction
between dcache and memory region attributes.
(dcache_xfer_memory): Add comment describing benefits of moving
cache writeback to a higher level.
(dcache_struct): Removed cache_has_stuff field. This was used to
record whether the cache had been accessed in order to invalidate
it when it was disabled. However, this is not needed because the
cache is write through and the code that enables, disables, and
deletes memory regions invalidate the cache. Add comment which
suggests that we could be more selective and only invalidate those
cache lines containing data from those memory regions.
(dcache_invalidate): Updated.
(dcache_xfer_memory): Updated.
(dcache_alloc): Don't abort() if dcache_enabled_p is clear.

appears to have been inadvertantly removed sometime in May 1999.
* Revert 2000-11-09 changes where shared library objects were
moved from NATDEPFILES to TDEPFILES on NetBSD targets. While
we'd like to be able to debug dynamically linked executables,
this makes it impossible to build a cross debugger on a many
hosts.

* config/powerpc/nbsd.mh: Likewise.
* config/sparc/nbsd.mh: Likewise.
a mangled symbol rather than recursing into lookup_symbol, since

(thread_db_push_target, thread_db_unpush_target): Remove
functions.
(deactivate_target): New function.
(thread_db_new_objfile): If OBJFILE == NULL, force deactivation of
target vector. Activate target vector directly instead of calling
thread_db_push_target. Set keep_thread_db if thread library is
detected in the main symbol file. Only enable thread event
reporting if there actually is a child process. Likewise for
detecting new threads, done by calling thread_db_find_new_threads
instead of iterating over the threads ourselves.
(thread_db_detach): Call deactivate_target instead of
thread_db_unpush_target.
(thread_db_wait): Bail out early if we're not debugging the
multi-threaded child process yet.

is defined.

Use the SUBDIR_GDBTK_* macros instead of hard coded file names.
* configure: Regenerate.
* configure.in: Fix a couple of typos in the handling of the
enable_gdbcli option. Make it check enableval for the result
of AC_ARG_ENABLE.
* configure: Regenerate.
* gdb.base/break.exp (test_clear_command): Use a marker function
rather than 'main' for the test function. Also move this
test to an execution point where the marker function names are
guaranteed to be bound to functions. (Executing tests after a
'finish' from main runs into name conflicts with local names
in __libc_start_main).
* dwarf2read.c (DWARF2_REG_TO_REGNUM): New macro. Provide default
definition. Will be used to translate between the compiler's
register numbering and GDB's (for register variables etc).

pointer.

(mips16_op): Delete macro.
(extended_mips16_next_pc): Rewrite of old mips16_next_pc function.
When an extended instruction do a recursive call.

and documentation.
