re PR debug/39267 (gdb testsuite regressions)
PR debug/39267
* tree.h (BLOCK_NONLOCALIZED_VARS, BLOCK_NUM_NONLOCALIZED_VARS,
BLOCK_NONLOCALIZED_VAR): New macros.
(tree_block): Add nonlocalized_vars.
* dwarf2out.c (gen_formal_parameter_die, gen_variable_die, gen_decl_die): Add
origin argument; allow generation of die with origin at hand only.
(gen_member_die, gen_type_die_with_usage, force_decl_die,
declare_in_namespace, gen_namescpace_die, dwarf2out_decl): Update use of gen_*.
(gen_block_die): Fix checking for unused blocks.
(process_scope_var): Break out from .... ; work with origins only.
(decls_for_scope) ... here; process nonlocalized list.
(dwarf2out_ignore_block): Look for nonlocalized vars.
* tree-ssa-live.c (remove_unused_scope_block_p): Look for nonlocalized vars.
(dump_scope_block): Dump them.
* tree-inline.c (remap_decls): Handle nonlocalized vars.
(remap_block): Likewise.
(can_be_nonlocal): New predicate.
(copy_bind_expr, copy_gimple_bind): Update use of remap_block.
