Specifically, the calling of inferiors methods is improved.
* value.h: New macros METHOD_PTR_IS_VIRTUAL,
METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
hide the implementation details of pointer-to-method objects.
How to tell if the pointer points to a virtual method is
still very dependent on the particular compiler, but this
should make it easier to find the places to change.
* eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
(val_print [case TYPE_CODE_PTR]): Use the new METHOD_PTR_*
macros, instead of a hard-wired-in code that incorrectly
assumed a no-longerused representation of pointer-to-method
values. And otherwise fix the relevant bit-rotted code.
* valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
If there are both fields and methods, put a space between.
* stabsread.c (read_struct_type): Fix bug in handling of
GNU C++ anonymous type (indicated by CPLUS_MARKER followed
by '_'). (It used to prematurely exit the loop reading in
the fields, so it would think it should start reading
methods while still in the fields. This could crash gdb
given a gcc that can emit nested type information.)
* valops.c (search_struct_method): Pass 'this' value by
reference instead of by value. This provides a more
consistent interface through a recursive search where the
"bottom" functions may need to adjust offsets (due to multiple
inheritance).
* valops.c, value.h, values.c: Pass extra parameters to
value_fn_field and value_virtual_fn_field so we can
correctly adjust offset for multiple inheritance.
* eval.c (evaluate_subexp [case OP_FUNCALL]): Simplify
virtual function calls by using value_virtual_fn_field().
* values.c: New function baseclass_offset, derived from
baseclass_addr (which perhaps can be made obsolete?).
It returns an offset rather than an address. This is a
cleaner interface since it doesn't mess around allocating
new values.
* valops.c (search_struct_method): Use baseclass_offset
rather than baseclass_addr.
previously deleted make-c-prog.awk. Converts a text file
to a c function that prints that text.
* flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
Inputs to gen-c-prog.awk, containing text describing
gprof output.
* blurbs.c: Removed. Use *_bl.c instead.
* Makefile.in: Use gen-cprog.awk to generate *_bl.c files
from *_bl.m files. Also, improve *clean rules.
* printgprof.c (printgprof): Usw new function names from *_bl.c.
* obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
support for C source listings. (obj_coff_endef): look in the right
part of the symbol for the symbol name
* remote-udi.c (udi_resume): Clean up.
* (udi_wait): Rewrite, leave out bugs.
* Add debugging code to print out all register fetches and stores.
* Straighten out target_ops.
* tm-29k.h (DUMMY_FRAME_RSIZE): Pad out to doubleword.
* remote-udi.c (udi_create_inferior): run with no arguments should
not pass the program name as an argument, since the UDI code
already handles that.
(udi_load): get the symbols from prog_name, not arg_string (the
load command should really use arg_string as the program name, not
prog_name, but at least the run command works now).
* am29k-tdep.c (_initialize_29k): Make it possible for the
user to set and query the address where function calls into the
inferior write a small scratch routine. `set call_scratch_address'
* inferior.h (PC_IN_CALL_DUMMY): Fix fencepost error.
* remote.c (remote_prepare_to_store): Only fetch regs if they are
not already cached validly.
* infptrace.c: remove #ifdef USG from around include ptrace.h.

* dwarfread.c (read_ofile_symtab): Initialize dbsize and use it.
* dwarfread.c (basicdieinfo): Use dbsize to check for oversize
DIEs as well as the current check for undersize DIEs. This helps
