(output_die): Skip DIE symbol output for the LTO added one.
Handle DIE symbol references with offset.
(output_comp_unit): Guard section name mangling properly.
For LTO debug sections emit a symbol at the section beginning
which we use to refer to its DIEs.
(add_abstract_origin_attribute): For DIEs registered via
dwarf2out_register_external_die directly refer to the early
DIE rather than indirectly through the shadow one we created.
Remove obsolete call to dwarf2out_abstract_function for
non-function/block origins.
(gen_array_type_die): When generating early LTO debug do
not emit DW_AT_string_length.
(gen_formal_parameter_die): Do not re-create DIEs for PARM_DECLs
late when in LTO. As suggested place a gcc_unreachable for
the DECL_ABSTRACT_P case.
(gen_subprogram_die): Avoid another specification DIE
for early built declarations/definitions for the late LTO case.
(gen_variable_die): Add type references for late duplicated VLA dies
when in late LTO.
(gen_inlined_subroutine_die): Do not call dwarf2out_abstract_function,
we have the abstract instance already.
(process_scope_var): Adjust decl DIE contexts in LTO which
first puts them in limbo.
(gen_decl_die): Do not generate type DIEs late apart from
types for VLAs or for decls we do not yet have a DIE. Do not
call dwarf2out_abstract_function late.
(dwarf2out_early_global_decl): Make sure to create DIEs
for abstract instances of a decl first.
(dwarf2out_late_global_decl): Adjust comment.
(output_macinfo_op): With multiple macro sections use
macinfo_label_base to distinguish labels.
(output_macinfo): Likewise. Update macinfo_label_base.
Pass in the line info label.
(note_variable_value_in_expr): When generating LTO resolve
all variable values here by generating DIEs as needed.
(init_sections_and_labels): Add early LTO debug flag parameter
and generate different sections and names if set. Add generation
counter for the labels so we can have multiple of them.
(reset_dies): Helper to allow DIEs to be output multiple times.
(dwarf2out_finish): When outputting DIEs to the fat part of an
LTO object first reset DIEs.
(dwarf2out_early_finish): Output early DIEs when generating LTO.
(modified_type_die): Check for decl_ultimate_origin being self
before recursing.
(gen_type_die_with_usage): Likewise.
(gen_typedef_die): Allow decl_ultimate_origin being self.
(set_decl_abstract_flags): Remove.
(set_block_abstract_flags): Likewise.
(dwarf2out_abstract_function): Treat the early generated DIEs
as the abstract copy and only add DW_AT_inline and
DW_AT_artificial here and call set_decl_origin_self.
If the DIE has an abstract origin don't do anything.
* tree.c (free_lang_data): Build a dummy TRANSLATION_UNIT_DECL
if we have none yet (Go fails to build one, PR78628).
(variably_modified_type_p): Prevent endless recursion for Ada
cyclic pointer types.

Force a TRANSLATION_UNIT_DECL DECL_CONTEXT for file-scope decls.
(output_function): Stream DECL_DEBUG_ARGS.
* tree-streamer-in.c (lto_input_ts_decl_common_tree_pointers):
Stream DECL_ABSTRACT_ORIGIN.
* tree-streamer-out.c (write_ts_decl_common_tree_pointers): Likewise.
(write_ts_decl_minimal_tree_pointers): Force a TRANSLATION_UNIT_DECL
DECL_CONTEXT for file-scope decls.
* lto-streamer.h (struct dref_entry): Declare.
(dref_queue): Likewise.
* cfgexpand.c (pass_expand::execute): Do not call the
outlining_inline_function hook here.
* lto-wrapper.c (debug_obj): New global.
(tool_cleanup): Unlink it if required.
(debug_objcopy): New function.
(run_gcc): Handle early debug sections in the IL files by
extracting them to separate files, partially linkin them and
feeding the result back as result to the linker.
* config/darwin.h (DEBUG_LTO_INFO_SECTION, DEBUG_LTO_ABBREV_SECTION,
DEBUG_LTO_MACINFO_SECTION, DEBUG_LTO_LINE_SECTION,
DEBUG_STR_LTO_SECTION, DEBUG_LTO_MACRO_SECTION): Put early debug
sections into a separate segment.

and generate different sections and names if set. Add generation
counter for the labels so we can have multiple of them.
(reset_dies): Helper to allow DIEs to be output multiple times.
(dwarf2out_finish): When outputting DIEs to the fat part of an
LTO object first reset DIEs.

(output_comp_unit): Guard section name mangling properly.
For LTO debug sections emit a symbol at the section beginning
which we use to refer to its DIEs.
(add_abstract_origin_attribute): For DIEs registered via
dwarf2out_register_external_die directly refer to the early
DIE rather than indirectly through the shadow one we created.
Remove obsolete call to dwarf2out_abstract_function for
non-function/block origins.
(gen_array_type_die): When generating early LTO debug do
not emit DW_AT_string_length.
(gen_formal_parameter_die): Do not re-create DIEs for PARM_DECLs
late when in LTO. As suggested place a gcc_unreachable for
the DECL_ABSTRACT_P case.
(gen_subprogram_die): Avoid another specification DIE
for early built declarations/definitions for the late LTO case.
(gen_variable_die): Add type references for late duplicated VLA dies
when in late LTO.
(gen_inlined_subroutine_die): Do not call dwarf2out_abstract_function,
we have the abstract instance already.
(process_scope_var): Adjust decl DIE contexts in LTO which
first puts them in limbo.
(gen_decl_die): Do not generate type DIEs late apart from
types for VLAs or for decls we do not yet have a DIE. Do not
call dwarf2out_abstract_function late.
(dwarf2out_early_global_decl): Make sure to create DIEs
for abstract instances of a decl first.
(dwarf2out_late_global_decl): Adjust comment.
(output_macinfo_op): With multiple macro sections use
macinfo_label_base to distinguish labels.
(output_macinfo): Likewise. Update macinfo_label_base.
Pass in the line info label.
(note_variable_value_in_expr): When generating LTO resolve
all variable values here by generating DIEs as needed.
(init_sections_and_labels): Add early LTO debug flag parameter
and generate different sections and names if set. Add generation
counter for the labels so we can have multiple of them.
(reset_dies): Helper to allow DIEs to be output multiple times.
(dwarf2out_finish): When outputting DIEs to the fat part of an
LTO object first reset DIEs.
(dwarf2out_early_finish): Output early DIEs when generating LTO.
(modified_type_die): Check for decl_ultimate_origin being self
before recursing.
(gen_type_die_with_usage): Likewise.
(gen_typedef_die): Allow decl_ultimate_origin being self.
(set_decl_abstract_flags): Remove.
(set_block_abstract_flags): Likewise.
(dwarf2out_abstract_function): Treat the early generated DIEs
as the abstract copy and only add DW_AT_inline and
DW_AT_artificial here and call set_decl_origin_self.
If the DIE has an abstract origin don't do anything.
* tree.c (free_lang_data): Build a dummy TRANSLATION_UNIT_DECL
if we have none yet (Go fails to build one, PR78628).
(variably_modified_type_p): Prevent endless recursion for Ada
cyclic pointer types.
* lto-streamer-in.c: Include debug.h.
(dref_queue): New global.
(lto_read_tree_1): Stream in DIE references.
(lto_input_tree): Register DIE references.
(input_function): Stream DECL_DEBUG_ARGS.
* lto-streamer-out.c: Include debug.h.
(lto_write_tree_1): Output DIE references.
(DFS::DFS_write_tree_body): Follow DECL_ABSTRACT_ORIGIN.
Force a TRANSLATION_UNIT_DECL DECL_CONTEXT for file-scope decls.
(output_function): Stream DECL_DEBUG_ARGS.
* tree-streamer-in.c (lto_input_ts_decl_common_tree_pointers):
Stream DECL_ABSTRACT_ORIGIN.
* tree-streamer-out.c (write_ts_decl_common_tree_pointers): Likewise.
(write_ts_decl_minimal_tree_pointers): Force a TRANSLATION_UNIT_DECL
DECL_CONTEXT for file-scope decls.
* lto-streamer.h (struct dref_entry): Declare.
(dref_queue): Likewise.
* cfgexpand.c (pass_expand::execute): Do not call the
outlining_inline_function hook here.
* lto-wrapper.c (debug_obj): New global.
(tool_cleanup): Unlink it if required.
(debug_objcopy): New function.
(run_gcc): Handle early debug sections in the IL files by
extracting them to separate files, partially linkin them and
feeding the result back as result to the linker.
* config/darwin.h (DEBUG_LTO_INFO_SECTION, DEBUG_LTO_ABBREV_SECTION,
DEBUG_LTO_MACINFO_SECTION, DEBUG_LTO_LINE_SECTION,
DEBUG_STR_LTO_SECTION, DEBUG_LTO_MACRO_SECTION): Put early debug
sections into a separate segment.
* config/darwin.c (darwin_asm_named_section): Handle __GNU_DWARF_LTO
segments.
(darwin_asm_dwarf_section): Likewise.
(darwin_asm_output_dwarf_offset): Likewise.
* config/i386/i386.c (make_resolver_func): Set DECL_IGNORED_P.
lto/
* lto.c (unify_scc): Truncate DIE reference queue for dropped SCCs.
(lto_read_decls): Process TRANSLATION_UNIT_DECLs. Remove
TYPE_DECL debug processing, register DIE references from
prevailing SCCs with the debug machinery.
(lto_section_with_id): Handle LTO debug sections.
libstdc++/
* testsuite/libstdc++-prettyprinters/prettyprinters.exp: Run all
tests with -flto as well if supported.
testsuite/
* c-c++-common/asan/global-overflow-1.c: Adjust diagnostic location
regex to handle the LTO case.
* c-c++-common/asan/heap-overflow-1.c: Likewise.
* c-c++-common/asan/misalign-1.c: Likewise.
* c-c++-common/asan/misalign-2.c: Likewise.
* c-c++-common/asan/null-deref-1.c: Likewise.
* c-c++-common/asan/stack-overflow-1.c: Likewise.
* c-c++-common/asan/strncpy-overflow-1.c: Likewise.
* c-c++-common/asan/use-after-free-1.c: Likewise.
