* target_def.h (TARGET_DWARF_HANDLE_FRAME_UNSPEC): Define to 0.
(TARGET_INITIALIZER): Add TARGET_DWARF_HANDLE_FRAME_UNSPEC.
* dwarf2out.c (dwarf2out_frame_debug_expr): Allow REG->REG move

(emit_stack_pointer_increment): Rename into gen_stack_pointer_inc.
(emit_stack_pointer_decrement): Rename into gen_stack_pointer_dec.
(expand_prologue): Adjust calls to emit_stack_pointer_{in,de}crement.
Set RTX_FRAME_RELATED_P on the appropriate insns and members of insns.
(sparc_asm_function_prologue): Do not emit call frame debugging info.
(emit_and_preserve): Adjust calls to emit_stack_pointer_{in,de}crement.
(sparc_expand_epilogue): Likewise.
