branch targets to compute target address using const from previous
instruction if necessary.
* Add `Q' operator to print out bit position field various
instructions.
* hppah-nat.c: #include sys/param.h, and sys/user.h. General
cleanups, use new code from Utah.
* (store_inferior_registers): Update to new code from Utah.
* (initialize_kernel_u_addr): Re-enable decl of struct user u.
* (fetch_register): Clear out priv level when reading PCs.
* hppah-tdep.c: Get rid of gobs of KERNELDEBUG stuff.
* Remove decl of errno, #include wait.h and target.h.
* (frame_saved_pc): Check `flags' pseudo-register to see if we
were inside of a kernel call. If so, then PC is in a different
register. Also, mask out bottom two bits of all PCs so as not to
confuse higher level code.
* (push_dummy_frame): Create from #define in tm-hppa.h.
* (find_dummy_frame_regs): Update from Utah.
* (hp_pop_frame): Create from #define in tm-hppa.h.
* (hp_restore_pc_queue): New, from Utah.
* (hp_push_arguments): Big fixes from Utah.
* (pa_do_registers_info, pa_print_registers): Only print out fp
regs upon request.
* (skip_trampoline_code): New routine to deal with stubs that
live in nowhereland between callers and callees.
* i860-tdep.c: Remove decl of attach_flag.
* infrun.c (wait_for_inferior): Add new macro
INSTRUCTION_NULLIFIED, which can tell if the instruction pointed
at by PC will be nullified. If so, then step the target once more
so as to avoid confusing the user.
* (just before step_over_function:): Use stop_func_start, not
stop_pc when checking for the existance of line number info.
stop_func_start will reflect the proper address of the target
routine, not of the stub that we may be traversing to get there.
* tm-hppa.h: define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE
to deal with the stubs that PA compilers sometimes stick between
callers and callees. Also, define FLAGS_REGNUM for access to the
`flags' pseudo-reg.
* (REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Use
memcpy, not bcopy.
* (CANNOT_STORE_REGISTER): New from Utah. Says that we can't
write gr0, PC regs, and PSW!
* (FRAME_FIND_SAVED_REGS): Bug fixes from Utah.
* (PUSH_DUMMY_FRAME, POP_FRAME): Make into real routines in
hppah-nat.c.
* (CALL_DUMMY, FIX_CALL_DUMMY): Fixes from Utah.
* Define struct unwind_table_entry.
* valops.c (call_function_by_hand): Add another arg to
FIX_CALL_DUMMY (under #ifdef GDB_TARGET_IS_HPPA). Why is this
necessary?
which together maintain a dynamically expandable static buffer
for the lexer to use when translating C strings to their internal
form (other future uses possible). Fix parsing of C style strings
to do the normal C style input conversions of escaped character
sequences.
* valops.c (value_string): Remove translation of escaped
character sequences, now done in C expression parser.
symtab.h, tm-i386v4.h, valprint.c, values.c: Lint.

Replace bcopy() use with memcpy(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.

Replace bcmp() use with memcmp(), which is more standard and can

remote-hms.c, remote-mm.c, remote-nindy.c, remote-vx.c, remote.c,
target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
Remove to_call_function and target_call_function, since it
always calls the same thing (call_function_by_hand).
only differences were in the specific trap vectors used and whether or not
an fpu was present. These are now handled by appropriate definitions of
BPT_VECTOR and HAVE_68881 respectively. Other minor obvious cleanups.
Minor spelling correction in valops.c.
machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)
* value.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
the correct pointer type to value_from_long{est}.
* remote-vx.c: Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).
* valops.c (value_string): Find malloc with lookup_misc_func, not
raw search.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.

* i386-tdep.c (i386_get_frame_setup): Use SWAP_TARGET_AND_HOST
before returning locals or slocals.
* i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
call to codestream_seek; add one to pos if (and only if)
we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).
Mon Apr 15 12:04:32 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
* valops.c (call_function_by_hand): Put dummy1 in target order
before FIX_CALL_DUMMY.

Sun Apr 14 11:55:19 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
* valops.c (push_word): Add SWAP_TARGET_AND_HOST.
* remote.c (remote_open): Send '+' before calling putpkt().
* tm-i386v.h (REGISTER_VIRTUAL_TYPE): Return pointer to void,
not int, for pc, fp, and sp.
