(ginline-points, ginternal-reset-location-views): New. * doc/invoke.texi: Document them. Use @itemx where intended. (gvariable-location-views): Adjust. * target.def (reset_location_view): New. * doc/tm.texi.in (DWARF2_ASM_VIEW_DEBUG_INFO): New. (TARGET_RESET_LOCATION_VIEW): New. * doc/tm.texi: Rebuilt. * dwarf2out.c (dwarf2out_default_as_loc_support): New. (dwarf2out_default_as_locview_support): New. (output_asm_line_debug_info): Use option variables. (dwarf2out_maybe_output_loclist_view_pair): Likewise. (output_loc_list): Likewise. (add_high_low_attributes): Check option variables. Don't output entry view attribute in strict mode. (gen_inlined_subroutine_die): Check option variables. (dwarf2out_inline_entry): Likewise. (init_sections_and_labels): Likewise. (dwarf2out_early_finish): Likewise. (maybe_reset_location_view): New, from... (dwarf2out_var_location): ... here. Call it. * debug.h (dwarf2out_default_as_loc_support): Declare. (dwarf2out_default_as_locview_support): Declare. * hooks.c (hook_int_rtx_insn_0): New. * hooks.h (hook_int_rtx_insn_0): Declare. * toplev.c (process_options): Take -gas-loc-support and -gas-locview-support from dwarf2out. Enable -gvariable-location-views by default only with locview assembler support. Enable -ginternal-reset-location-views by default only if the target defines the corresponding hook. Enable -ginline-points by default if location views are enabled; force it disabled if statement frontiers are disabled. * tree-inline.c (expand_call_inline): Check option variables. * tree-ssa-live.c (remove_unused_scope_block_p): Likewise.
