* dbxread.c, partial-stab.h: Replace all #ifdef hp9000s800's with
GDB_TARGET_IS_HPPA's. This is a SERIOUS KLUDGE. The code needs to all
be ripped out and reimplemented right (see elfread.c).
* tm-hppa.h (GDB_TARGET_IS_HPPA): Define.
fix to differentiate between gcc1 & gcc2 compiled files so that we
can debug calls that pass structs as args correctly.
* symmisc.c (dump_symtab): If block was compiled with gcc, say
so, and what version.
prevent crashes when examining cross-targets.
* dbxread.c (process_one_symbol): Include directory name when
calling start_subfile for SOL & BINCL symbols. This allows gdb to
find include files, and yacc/lex sources when the cwd doesn't match
that in which the object was compiled.
* objfiles.h (ALL_MSYMBOLS): Don't seg fault when there are no
msymbols.
* symtab.c (lookup_symtab_1): Rewrite. It now handles include
files.
* dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.".
* procfs.c (proc_set_exec_trap): Set run-on-last-close flag on
child processes, to avoid dead ones "hanging around" after GDB exits.

when attaching running processes, so it will continue if we detach
it, quit, or are killed.
(detach): Clear faults and set RLC flag to make process run
when we close it.
(open_proc_file): New `mode' argument for O_RDONLY or O_RDWR.
Callers changed.
(info_proc): Open process O_RDONLY, so we can see any process,
even those controlled by debuggers.
* tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).
single `addr' or `offset'. This makes Solaris-2 support work, and
permits better VxWorks (and maybe xcoff) support later.
* dbxread.c: Conforming changes.

CODE or DATA section attachment. This eliminates a lot of random
values from shared libraries, which screw up the ordinary symbols
in the address ranges they happen to overlap.
* buildsym.c (define_symbol): Eliminate special tests
for function types; move into "function" cases in switch statement.
(define_symbol: 'f', 'F', 'P'): Process all parameter types

ieee-float.c, infcmd.c, sparc-tdep.c, stack.c, symtab.c, symtab.h,

take advantage of gcc's builtin functions for increased performance.

variable. Add `set' and `show' commands for it.

(Bug and fix found by Pierre Willard.)

C++ lookups fail, print possibly helpful hint about completion.

for static data members.
* dbxread.c (dbx_psymtab_to_symtab_1): Fix prototype.
* config/ncr3000.mh (INSTALL): Don't use /usr/ucb/install,
it's broken on ncr3000's.

scanning all the rest of the psymtabs.
(process_one_symbol): Fix comments around N_OBJ, N_OPT, N_UNDF.
* buildsym.h (N_UNDF): Improve comments.
