* hppa-pinsn.c (print_insn): Improve handling of be and ble
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?
