Alexandre Oliva bd2b9f1e2d [LVU] Introduce location views
This patch introduces an option to enable the generation of location
views along with location lists.  The exact format depends on the
DWARF version: it can be a separate attribute (DW_AT_GNU_locviews) or
(DW_LLE_view_pair) entries in DWARF5+ loclists.

Line number tables are also affected.  If the assembler is found, at
compiler build time, to support .loc views, we use them and
assembler-computed view labels, otherwise we output compiler-generated
line number programs with conservatively-computed view labels.  In
either case, we output view information next to line number changes
when verbose assembly output is requested.

This patch requires an LVU patch that modifies the exported API of
final_scan_insn.  It also expects the entire SFN patchset to be
installed first, although SFN is not a requirement for LVU.

Jiong Wang ff971abe60 Add DW_CFA_AARCH64_negate_ra_state to dwarf2.def/h and dwarfnames.c
A new vendor CFA DW_CFA_AARCH64_negate_ra_state was introduced for ARMv8.3-A
return address signing, it is multiplexing DW_CFA_GNU_window_save in CFA vendor
extension space.

  This patch adds necessary code to make it available to external, the GDB
patch (https://sourceware.org/ml/gdb-patches/2017-08/msg00215.html) is intended
to use it.

  A new DW_CFA_DUP for it is added in dwarf2.def.  The use of DW_CFA_DUP is to
avoid duplicated case value issue when included in libiberty/dwarfnames.

  Native x86 builds OK to make sure no macro expanding errors.

Committed on behalf of Jiong Wang.

Dodji Seketeli d40a19da13 re PR debug/41266 (Emit DW_TAG_template_parameter_pack and DW_TAG_formal_parameter_pack)
Fix for PR debug/41266

ChangeLog:

	* include/dwarf2.h (enum dwarf_tag): Add
	DW_TAG_template_parameter_pack and DW_TAG_formal_parameter_pack.

gcc/ChangeLog:

	* dwarf2out.c (template_parameter_pack_die,
	gen_formal_parameter_pack_die ): New functions.
	(make_ith_pack_parameter_name): Remove this function.
	(dwarf_tag_name): Support printing DW_TAG_template_parameter_pack and
	DW_TAG_formal_parameter_pack.
	(gen_generic_params_dies): Represent each template parameter pack
	by a DW_TAG_template_parameter_pack DIE. Argument pack elements are
	represented by usual DW_TAG_template_*_parameter DIEs that are
	children of the DW_TAG_template_parameter_pack element DIE.
	(generic_parameter_die): This doesn't deal with parameter pack
	names anymore. Don't generate DW_AT_name for some DIEs, e.g. children of
	parameter pack DIEs.
	(gen_formal_parameter_die): Add a flag to not emit DW_AT_name
	in certain cases, e.g. for pack elements.
	(gen_formal_types_die, gen_decl_die): Adjust usage of
	gen_formal_parameter_die.
	(gen_subprogram_die): Represent each function parameter pack by a
	DW_TAG_formal_parameter_pack DIE. Arguments of of the pack are
	represented by usual DW_TAG_formal_parameter DIEs that are children
	of the DW_TAG_formal_parameter_pack DIE. Remove references to
	____builtin_va_alist decls as no part of the compiler uses those
	anymore.
	* langhooks.h (struct lang_hooks_for_decls): Add
	function_parm_expanded_from_pack_p, get_generic_function_decl
	and function_parameter_pack_p hooks.  Fix comment for
	get_innermost_generic_parms hook.
	* langhooks-def.h (LANG_HOOKS_FUNCTION_PARAMETER_PACK_P,
	LANG_HOOKS_FUNCTION_PARM_EXPANDED_FROM_PACK_P ): Declare new hook
	macros and use them to initialize lang_hook.

gcc/cp/ChangeLog:

	* cp-lang.c (LANG_HOOKS_FUNCTION_PARAMETER_PACK_P,
	LANG_HOOKS_FUNCTION_PARM_EXPANDED_FROM_PACK_P,
	LANG_HOOKS_GET_GENERIC_FUNCTION_DECL): Initialize these
	hooks for the c++ FE.
	* cp-tree.h (function_parameter_pack_p, get_function_template_decl,
	function_parameter_expanded_from_pack_p): Declare ...
	* pt.c (function_parameter_pack_p, get_function_template_decl,
	function_parameter_expanded_from_pack_p): ... new hooks.
	(get_template_info): Make this more robust.
	(template_args_variadic_p, make_ith_pack_parameter_name): Add a new
	line between comment and function.
	(get_template_argument_pack_elems): Fix comment.
	(tsubst_decl): Arguments of function parameter packs are not
	parameter packs themselves.

gcc/testsuite/ChangeLog:
	* g++.dg/debug/dwarf2/template-func-params-4.C: Adjust.
	* g++.dg/debug/dwarf2/template-func-params-7.C: Likewise.
	* g++.dg/debug/dwarf2/template-params-4.C: Likewise.
