+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.

+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.

+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.

+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.

+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.

+
+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.

+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).

+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.

+Subject: [PATCH] c++: Alias template instantiation template info
+
+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)

+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.

+
+Currently we provide a separate implementation of Stream_Attributes via
+s-stratt__xdr.adb which needs to be recompiled manually.
+
+This change introduces instead a new binder switch to choose at bind
+time which stream implementation to use and replaces s-stratt__xdr.adb
+by a new unit System.Stream_Attributes.XDR.

+Subject: [PATCH] c++: Fix --disable-bootstrap with older g++.
+
+Previously I had AX_CXX_COMPILE_STDCXX in the gcc directory configure, which
+added -std=c++11 to CXX if needed, but then CXX is overridden from the
+toplevel directory, so it didn't have the desired effect.  Fixed by moving
+the check to the toplevel.  Currently it is only used when building GCC
+without bootstrapping; other packages that share the toplevel directory
+can adjust the condition if they also want to require C++11 support.
+
+ChangeLog:
+
+       * configure.ac: Check AX_CXX_COMPILE_STDCXX if not bootstrapping.
+       * configure: Regenerate.
+
+gcc/ChangeLog:
+
+       * aclocal.m4: Remove ax_cxx_compile_stdcxx.m4.
+       * configure.ac: Remove AX_CXX_COMPILE_STDCXX.
+       * configure: Regenerate.
