(MIN_SAVE_FPR, MAX_SAVE_FPR): Don't define.
(ppc64_elf_func_desc_adjust): Use sfpr_define in place of existing
code. Define all ABI mandated _save and _rest functions.
* gdb.base/sigstep.exp (breakpoint_to_handler, skip_to_handler)
(skip_over_handler, breakpoint_over_hander): New test procedures.
(advance, advancei): Add a proper prefix, do not use
rerun_to_main.
* gdb.base/sigstep.c (main): Change to use an infinite loop.
* infrun.c (struct execution_control_state): Delete field
"stepping_through_sigtramp".
(init_execution_control_state): Do not set same.
(context_switch): Do not pass same to save_infrun_state and
load_infrun_state.
* gdbthread.h (struct thread_info): Delete field
stepping_through_sigtramp.
(save_infrun_state, load_infrun_state): Delete parameter
stepping_through_sigtramp.
* thread.c (load_infrun_state, save_infrun_state): Update.
'num_pieces' and 'pieces', for returning the result of an
expression that uses DW_OP_piece.
(struct dwarf_expr_piece): New struct type.
* dwarf2expr.c (new_dwarf_expr_context): Initialize num_pieces and
pieces.
(free_dwarf_expr_context): Free pieces, if any.
(add_piece): New function.
(execute_stack_op): Implement DW_OP_piece.
* dwarf2loc.c (dwarf2_evaluate_loc_desc): If the result of the
expression is a list of pieces, print an error message.
(dwarf2_loc_desc_needs_frame): If the expression yields
pieces, and any piece is in a register, then we need a frame.
altmac2.[sd]: ... to here.
excl.s: New.
gas.exp: Suppress both tests for a few targets known to break. Run the new
(split out) test only when the target doesn't use '!' as a comment character.
Reorder includes.
(fetch_register, store_register): Remove prototypes.
(child_resume): Reorganize code and comments such that it is
grouped a bit more logically.
(attach): Explicitly compare errno against 0.
(detach): Likewise. Use perror_with_name instead of
print_sys_errmsg.
* Makefile.in (infptrace.o): Update dependencies.
from CORE_ADDR to struct frame_info *. Use

(amd64_linux_sigtramp_p): Adjust for changed signature of
and64_linux_sigtramp_start
