* gdb/hppa-pinsn.c (print_insn): Handle 'r' and 'R' for break, rsm,
and ssm instructions.
* gdb/hppa-tdep.c (extract_5r_store, extract_5R_store): New
helper functions for print_insn.
read_memory to get byte order right.
* hppah-tdep.c (find_unwind_info): Don't read in unwind info
anymore. This is done in paread.c now. We expect unwind info
to hang off of objfiles, and search all of the objfiles when until
we find a match.
* (skip_trampoline_code): Cast arg to target_read_memory.
* objfiles.h (struct objfile): Add new field obj_private to hold
per object file private data (unwind info in this case).
* paread.c (read_unwind_info): New routine to read unwind info
for the objfile. This data is hung off of obj_private.
* tm-hppa.h: Define struct obj_unwind_info, to hold pointers to
the unwind info for this objfile. Also define OBJ_UNWIND_INFO to
make this easier to access.
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?
decl for attach_flag, it now lives in inferior.h.
* hppa-pinsn.c: Reformat opcode tables. Add function prototypes.
Make most functions static.
* hppah-nat.c: General cleanups, remove BSD specific code (since
that all lives in hppab-nat.c).
* hppah-tdep.c (frame_chain_valid), tm-hppa.h (FRAME_CHAIN):
Change sense of test against inside_entry_file(). This fix is
from U. of Utah.
* tm-hppa.h (PUSH_DUMMY_FRAME, POP_FRAME): Use char * for 2nd arg
to read/write_register_bytes().
