=== 0342-ARC-Propagate-uncached-type-attribute-to-each-member.patch ===
From 62a715c706d8482560dadfa9ead0766f3c20e434 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0342/2034] [ARC] Propagate uncached type attribute to each
 member of a struct.

Like `packed` type attribute, the ARC's `uncached` type attribute
needs to be propagated to each member of the struct where it is used,
triggering the .di flag for any access of the struct members. However,
any complex CFG manipulation may drop memory pointer type attributes,
leading to the impossibility to discriminate the direct accesses from
normal ones. To solve this issue, we will treat the direct memory
accessed specially via unspecs.

=== 0814-sra-Avoid-totally-scalarizing-overallping-field_decl.patch ===
From 665c5bad168ab63629b29ed2ce08ed042c088dc2 Mon Sep 17 00:00:00 2001
From: Martin Jambor <mjambor@suse.cz>
Date: Wed, 19 Feb 2020 11:08:40 +0100
Subject: [PATCH 0814/2034] sra: Avoid totally scalarizing overallping
 field_decls (PR 93667)

[[no_unique_address]] C++ attribute can cause two fields of a
RECORD_TYPE overlap, which currently confuses the totally scalarizing
code into creating invalid access tree.  For GCC 10, I'd like to
simply disable total scalarization of types where this happens.

For GCC 11 I'll write down a TODO item to enable total scalarization
of cases like this where the problematic fields are basically empty -
despite having a non-zero size - i.e. when they are just RECORD_TYPEs
without any data fields.

	PR tree-optimization/93667
	* tree-sra.c (scalarizable_type_p): Return false if record fields
	do not follow wach other.

Subject: [PATCH 2004/2034] amdgcn: Check HSA return codes [PR94629]

Ensure that the returned status values are not ignored.  The old code was
not broken, but this is both safer and satisfies static analysis.

Subject: [PATCH 0198/2034] Change recursive prepare_block_for_update to use a
 worklist

Reported as PR 93321, prepare_block_for_update with some huge
recusive inlining can go past the stack limit. Transforming this
recursive into worklist improves the stack usage here and we no
longer seg fault for the testcase.  Note the order we walk the siblings
change.

ChangeLog:
	PR tree-opt/93321
	* tree-into-ssa.c (prepare_block_for_update_1): Split out from ...
	(prepare_block_for_update): This.  Use a worklist instead of recursing.

=== 0184-PR-80005-Fix-__has_include.patch ===
From ad1a3914ae8d67c94b0d2428e3f9672e7db491a1 Mon Sep 17 00:00:00 2001
From: Nathan Sidwell <nathan@acm.org>
Date: Mon, 20 Jan 2020 05:39:59 -0800
Subject: [PATCH 0184/2034] [PR 80005]  Fix __has_include

__has_include is funky in that it is macro-like from the POV of #ifdef and
friends, but lexes its parenthesize argument #include-like.  We were
failing the second part of that, because we used a forwarding macro to an
internal name, and hence always lexed the argument in macro-parameter
context.  We componded that by not setting the right flag when lexing, so
it didn't even know.  Mostly users got lucky.

This reimplements the handline.
1) Remove the forwarding, but declare object-like macros that
expand to themselves.  This satisfies the #ifdef requirement

2) Correctly set angled_brackets when lexing the parameter.  This tells
the lexer (a) <...> is a header name and (b) "..." is too (not a string).

3) Remove the in__has_include lexer state, just tell find_file that that's
what's happenning, so it doesn't emit an error.

We lose the (undocumented) ability to #undef __has_include.  That may well
have been an accident of implementation.  There are no tests for it.

We gain __has_include behaviour for all users of the preprocessors -- not
just the C-family ones that defined a forwarding macro.

	libcpp/
	PR preprocessor/80005
	* include/cpplib.h (BT_HAS_ATTRIBUTE): Fix comment.
	* internal.h (struct lexer_state): Delete in__has_include field.
	(struct spec_nodes): Rename n__has_include{,_next}__ fields.

	* expr.c (parse_defined): Use _cpp_defined_macro_p.
	(eval_token): Adjust parse_has_include calls.
	(parse_has_include): Add OP parameter.  Reimplement.
	* files.c (_cpp_find_file): Add HAS_INCLUDE parm.  Use it to
	inhibit error message.
	(_cpp_stack_include): Adjust _cpp_find_file call.
	(_cpp_fake_include, _cpp_compare_file_date): Likewise.
	(open_file_failed): Remove in__has_include check.

	macros.
	(cpp_read_main_file): Adjust _cpp_find_file call.
	* pch.c (cpp_read_state): Adjust __has_include{,_next} access.
	* traditional.c (_cpp_scan_out_locgical_line): Likewise.

	gcc/c-family/

=== 1699-combine-Fix-split_i2i3-ICE-PR94291.patch ===
From c23c899aedf11069e992eed7358802b262d62f98 Mon Sep 17 00:00:00 2001
From: Jakub Jelinek <jakub@redhat.com>
Date: Tue, 7 Apr 2020 21:30:12 +0200
Subject: [PATCH 1699/2034] combine: Fix split_i2i3 ICE [PR94291]

The following testcase ICEs on armv7hl-linux-gnueabi.
try_combine is called on:
(gdb) p debug_rtx (i3)
(insn 20 12 22 2 (set (mem/c:SI (plus:SI (reg/f:SI 102 sfp)
                (const_int -4 [0xfffffffffffffffc])) [1 x+0 S4 A32])
        (reg:SI 125)) "pr94291.c":7:8 241 {*arm_movsi_insn}
     (expr_list:REG_DEAD (reg:SI 125)
        (nil)))
(gdb) p debug_rtx (i2)
(insn 12 7 20 2 (parallel [
            (set (reg:CC 100 cc)
                (compare:CC (reg:SI 121 [ <retval> ])
                    (const_int 0 [0])))
            (set (reg:SI 125)
                (reg:SI 121 [ <retval> ]))
        ]) "pr94291.c":7:8 248 {*movsi_compare0}
     (expr_list:REG_UNUSED (reg:CC 100 cc)
        (nil)))
and tries to recognize cc = r121 cmp 0; [sfp-4] = r121 parallel,
but that isn't recognized, so it splits it into two: split_i2i3
[sfp-4] = r121 followed by cc = r121 cmp 0 which is recognized, but
ICEs because the code below insist that the SET_DEST of newi2pat
(or first set in PARALLEL thereof) must be a REG or SUBREG of REG,
but it is a MEM in this case.  I don't see any condition that would
guarantee that, perhaps for the swap_i2i3 case it was somehow guaranteed.

As the code just wants to update LOG_LINKS and LOG_LINKS are only for
registers, not for MEM or anything else, the patch just doesn't update those
if it isn't a REG or SUBREG of REG.

2020-04-07  Jakub Jelinek  <jakub@redhat.com>

	PR rtl-optimization/94291
	PR rtl-optimization/84169
	* combine.c (try_combine): For split_i2i3, don't assume SET_DEST
	must be a REG or SUBREG of REG; if it is not one of these, don't
	update LOG_LINKs.

	* gcc.dg/pr94291.c: New test.

=== 0001-Add-patch_area_size-and-patch_area_entry-to-crtl.patch ===
From 6607bdd99994c834f92fce924abdaea3405f62dc Mon Sep 17 00:00:00 2001
From: "H.J. Lu" <hjl.tools@gmail.com>
Date: Fri, 1 May 2020 21:03:10 -0700
Subject: [PATCH] Add patch_area_size and patch_area_entry to crtl

Currently patchable area is at the wrong place.  It is placed immediately
after function label and before .cfi_startproc.  A backend should be able
to add a pseudo patchable area instruction durectly into RTL.  This patch
adds patch_area_size and patch_area_entry to crtl so that the patchable
area info is available in RTL passes.

It also limits patch_area_size and patch_area_entry to 65535, which is
a reasonable maximum size for patchable area.

gcc/

	PR target/93492
	* cfgexpand.c (pass_expand::execute): Set crtl->patch_area_size
	and crtl->patch_area_entry.
	* emit-rtl.h (rtl_data): Add patch_area_size and patch_area_entry.
	* opts.c (common_handle_option): Limit
	function_entry_patch_area_size and function_entry_patch_area_start
	to USHRT_MAX.  Fix a typo in error message.
	* varasm.c (assemble_start_function): Use crtl->patch_area_size
	and crtl->patch_area_entry.
	* doc/invoke.texi: Document the maximum value for
	-fpatchable-function-entry.

gcc/c-family/

	PR target/12345
	* c-attribs.c (handle_patchable_function_entry_attribute): Limit
	value to USHRT_MAX (65535).

From aedd04caa945260ea77fd22f29b77292f7dba72e Mon Sep 17 00:00:00 2001

Subject: [PATCH 1957/2034] c++: generic lambda forwarding function [PR94546]

While instantiating test(Plot) we partially instantiate the generic lambda.
We look at forward<T>(rest)... and see that it's just replacing parameter
packs with new parameter packs and tries to do a direct substitution.  But
because register_parameter_specializations had built up a
NONTYPE_ARGUMENT_PACK around the new parameter pack, the substitution
failed.  So let's not wrap it that way.

Subject: [PATCH 0577/2034] aarch64: Add an and/ior-based movk pattern
 [PR87763]

This patch adds a second movk pattern that models the instruction
as a "normal" and/ior operation rather than an insertion.  It fixes
the third insv_1.c failure in PR87763, which was a regression from
GCC 8.

	* config/aarch64/aarch64-protos.h (aarch64_movk_shift): Declare.

=== 1999-rs6000-Fix-C-14-vs.-C-17-ABI-bug-on-powerpc64le-PR94.patch ===
From a39ed81b8a0b46320a7c6ece3f7ad4c3f8519609 Mon Sep 17 00:00:00 2001
From: Jakub Jelinek <jakub@redhat.com>
Date: Thu, 23 Apr 2020 09:59:57 +0200
Subject: [PATCH 1999/2034] rs6000: Fix C++14 vs. C++17 ABI bug on powerpc64le
 [PR94707]

As mentioned in the PR and on IRC, the recently added struct-layout-1.exp
new tests FAIL on powerpc64le-linux (among other targets).
FAIL: tmpdir-g++.dg-struct-layout-1/t032 cp_compat_x_tst.o-cp_compat_y_tst.o execute
FAIL: tmpdir-g++.dg-struct-layout-1/t058 cp_compat_x_tst.o-cp_compat_y_tst.o execute
FAIL: tmpdir-g++.dg-struct-layout-1/t059 cp_compat_x_tst.o-cp_compat_y_tst.o execute
in particular.  The problem is that the presence or absence of the C++17
artificial empty base fields, which have non-zero TYPE_SIZE, but zero
DECL_SIZE, change the ABI decisions, if it is present (-std=c++17), the type
might not be considered homogeneous, while if it is absent (-std=c++14), it
can be.

The following patch fixes that and emits a -Wpsabi inform; perhaps more
often than it could, because the fact that rs6000_discover_homogeneous_aggregate
returns true when it didn't in in GCC 7/8/9 with -std=c++17 doesn't still
mean it will make a different ABI decision, but the warning triggered only
on the test I've changed (the struct-layout-1.exp tests use -w -Wno-psabi
already).

2020-04-23  Jakub Jelinek  <jakub@redhat.com>

	PR target/94707
	* config/rs6000/rs6000-call.c (rs6000_aggregate_candidate): Add
	cxx17_empty_base_seen argument.  Pass it to recursive calls.
	Ignore cxx17_empty_base_field_p fields after setting
	*cxx17_empty_base_seen to true.
	(rs6000_discover_homogeneous_aggregate): Adjust
	rs6000_aggregate_candidate caller.  With -Wpsabi, diagnose homogeneous
	aggregates with C++17 empty base fields.

	* g++.dg/tree-ssa/pr27830.C: Use -Wpsabi -w for -std=c++17 and higher.

=== 0001-Add-patch_area_size-and-patch_area_entry-to-crtl.patch ===
From 6607bdd99994c834f92fce924abdaea3405f62dc Mon Sep 17 00:00:00 2001
From: "H.J. Lu" <hjl.tools@gmail.com>
Date: Fri, 1 May 2020 21:03:10 -0700
Subject: [PATCH] Add patch_area_size and patch_area_entry to crtl

Currently patchable area is at the wrong place.  It is placed immediately
after function label and before .cfi_startproc.  A backend should be able
to add a pseudo patchable area instruction durectly into RTL.  This patch
adds patch_area_size and patch_area_entry to crtl so that the patchable
area info is available in RTL passes.

It also limits patch_area_size and patch_area_entry to 65535, which is
a reasonable maximum size for patchable area.

gcc/

	PR target/93492
	* cfgexpand.c (pass_expand::execute): Set crtl->patch_area_size
	and crtl->patch_area_entry.
	* emit-rtl.h (rtl_data): Add patch_area_size and patch_area_entry.
	* opts.c (common_handle_option): Limit
	function_entry_patch_area_size and function_entry_patch_area_start
	to USHRT_MAX.  Fix a typo in error message.
	* varasm.c (assemble_start_function): Use crtl->patch_area_size
	and crtl->patch_area_entry.
	* doc/invoke.texi: Document the maximum value for
	-fpatchable-function-entry.

gcc/c-family/

	PR target/12345
	* c-attribs.c (handle_patchable_function_entry_attribute): Limit
	value to USHRT_MAX (65535).

From 5194b51ed9714808d88827531e91474895b6c706 Mon Sep 17 00:00:00 2001
From: Jason Merrill <jason@redhat.com>
Date: Thu, 16 Jan 2020 16:55:39 -0500
Subject: [PATCH 0121/2034] PR c++/93286 - ICE with __is_constructible and
 variadic template.

Here we had been recursing in tsubst_copy_and_build if type2 was a TREE_LIST
because that function knew how to deal with pack expansions, and tsubst
didn't.  But tsubst_copy_and_build expects to be dealing with expressions,
so we crash when trying to convert_from_reference a type.

gcc/cp/ChangeLog:
	PR ipa/12345
	* pt.c (tsubst) [TREE_LIST]: Handle pack expansion.
	(tsubst_copy_and_build) [TRAIT_EXPR]: Always use tsubst for type2.

gcc/testsuite/ChangeLog:
	* g++.dg/ext/is_constructible4.C: New file.

I discovered that the alias instantiation machinery would setup
template_info, and then sometime later overwrite that with equivalent
info.  This broke modules, because the template info, once set, is
logically immutable.  Let's just not do that.

	* pt.c (lookup_template_class_1): Do not reinit template_info of an
	alias here.

(cherry picked from commit 74744bb1f2847b5b9ce3e97e0fec9c23bb0e499f)

=== 0001-RISC-V-Make-unique.patch ===
From adce62f53d8ad00e8110a6a2de7962d7a850de16 Mon Sep 17 00:00:00 2001

Subject: [PATCH] RISC-V: Make unique SECCAT_SRODATA names start with .srodata
 (not .sdata2)

default_unique_section uses ".sdata2" as a prefix for SECCAT_SRODATA
unique sections, but RISC-V uses ".srodata" instead. Override the
TARGET_ASM_UNIQUE_SECTION function to catch this case, allowing the
default to be used for all other sections.

gcc/
	* config/riscv/riscv.c (riscv_unique_section): New.
	(TARGET_ASM_UNIQUE_SECTION): New.

=== 0001-Fortran-ProcPtr-function.patch ===
From eb069ae8819c3a84d7f78becc5501e21ee3a9554 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fortran  : ProcPtr function results: 'ppr@' in error message
 PR39695

The value 'ppr@' is set in the name of result symbol, the actual
name of the symbol is in the procedure name symbol pointed
to by the result symbol's namespace (ns). When reporting errors for
symbols that have the proc_pointer attribute check whether the
result attribute is set and set the name accordingly.

2020-05-20  Mark Eggleston  <markeggleston@gcc.gnu.org>

gcc/fortran/

	PR fortran/39695
	* resolve.c (resolve_fl_procedure): Set name depending on
	whether the result attribute is set.  For PROCEDURE/RESULT
	conflict use the name in sym->ns->proc_name->name.
	* symbol.c (gfc_add_type): Add check for function and result
	attributes use sym->ns->proc_name->name if both are set.
	Where the symbol cannot have a type use the name in
	sym->ns->proc_name->name.

2020-05-20  Mark Eggleston  <markeggleston@gcc.gnu.org>

=== 0001-c-C-20-DR-2237.patch ===
From 4b38d56dbac6742b038551a36ec80200313123a1 Mon Sep 17 00:00:00 2001
From: Marek Polacek <polacek@redhat.com>

Subject: [PATCH] c++: C++20 DR 2237, disallow simple-template-id in cdtor.

This patch implements DR 2237 which says that a simple-template-id is
no longer valid as the declarator-id of a constructor or destructor;
see [diff.cpp17.class]#2.  It is not explicitly stated but out-of-line
destructors with a simple-template-id are also meant to be ill-formed
now.  (Out-of-line constructors like that are invalid since DR1435 I
think.)  This change only applies to C++20; it is not a DR against C++17.

I'm not crazy about the diagnostic in constructors but ISTM that
cp_parser_constructor_declarator_p shouldn't print errors.

	DR 2237
	* parser.c (cp_parser_unqualified_id): Reject simple-template-id as
	the declarator-id of a destructor.
