+Subject: [PATCH] c++: designated init with anonymous union [PR100489]
+
+My patch for PR98463 added an assert that tripped on this testcase, because
+we ended up with a U CONSTRUCTOR with an initializer for a, which is not a
+member of U. We need to wrap the a initializer in another CONSTRUCTOR for
+the anonymous union.
+
+There was already support for this in process_init_constructor_record, but
+not in process_init_constructor_union. But since this is about brace
+elision, it really belongs under reshape_init rather than digest_init, so
+this patch moves the handling to reshape_init_class, which also handles
+unions.
+
+ PR c++/100489
+
+gcc/cp/ChangeLog:
+
+ * decl.c (reshape_init_class): Handle designator for
+ member of anonymous aggregate here.
+ * typeck2.c (process_init_constructor_record): Not here.
+

+Subject: [PATCH] c++: "perfect" implicitly deleted move [PR100644]
+
+Here we were ignoring the template constructor because the implicit move
+constructor had all perfect conversions. But CWG1402 says that an
+implicitly deleted move constructor is ignored by overload resolution; we
+implement that instead by preferring any other candidate in joust, to get
+better diagnostics, but that means we need to handle that case here as well.

+Subject: [PATCH] arm: Remove use of opts_set in arm_configure_build_target
+ [PR100767]
+
+The variable global_options_set is a reflection of which options have
+been explicitly set from the command line in the structure
+global_options. But it doesn't describe the contents of a
+cl_target_option. cl_target_option is a set of options to apply and
+once configured should represent a viable set of options without
+needing to know which were explicitly set by the user.
+
+Unfortunately arm_configure_build_target was incorrectly conflating
+the two. Fortunately, however, we do not really need to know this
+since the various override_options functions should have sanitized the
+target_options values before constructing a cl_target_option
+structure. It is safe, therefore, to simply drop this parameter to
+arm_configure_build_target and rely on checking that various string
+parameters are non-null before dereferencing them.
+
+gcc:
+
+ PR target/100767
+ * config/arm/arm.c (arm_configure_build_target): Remove parameter
+ opts_set, directly check opts parameters for being non-null.
+ (arm_option_restore): Update call to arm_configure_build_target.
+ (arm_option_override): Likewise.
+ (arm_can_inline_p): Likewise.
+ (arm_valid_target_attribute_tree): Likewise.
+ * config/arm/arm-c.c (arm_pragma_target_parse): Likewise.
+ * config/arm/arm-protos.h (arm_configure_build_target): Adjust
+ prototype.

+Subject: [PATCH] c++: tsubst_function_decl and excess arg levels [PR100102]
+
+Here, when instantiating the dependent alias template
+duration::__is_harmonic with args={{T,U},{int}}, we find ourselves
+substituting the function decl _S_gcd. Since we have more arg levels
+than _S_gcd has parm levels, an old special case in tsubst_function_decl
+causes us to unwantedly reduce args to its innermost level, yielding
+args={int}, which leads to a nonsensical substitution into the decl
+context and eventually a crash.
+
+The comment for this special case refers to three examples for which we
+ought to see more arg levels than parm levels here, but none of the
+examples actually demonstrate this. In the first example, when
+defining S<int>::f(U) parms_depth is 2 and args_depth is 1, and
+later when instantiating say S<int>::f<char> both depths are 2. In the
+second example, when substituting the template friend declaration
+parms_depth is 2 and args_depth is 1, and later when instantiating f
+both depths are 1. Finally, the third example is invalid since we can't
+specialize a member template of an unspecialized class template like
+that.
+
+Given that this reduction code seems no longer relevant for its
+documented purpose and that it causes problems as in the PR, this patch
+just removes it. Note that as far as bootstrap/regtest is concerned,
+this code is dead; the below two tests would be the first to reach it.
+

+Subject: [PATCH] libsanitizer: Remove cyclades inclusion in sanitizer
+
+The Linux kernel has removed the interface to cyclades from
+the latest kernel headers[1] due to them being orphaned for the
+past 13 years.
+
+libsanitizer uses this header when compiling against glibc, but
+glibcs itself doesn't seem to have any references to cyclades.
+
+Further more it seems that the driver is broken in the kernel and
+the firmware doesn't seem to be available anymore.
+
+As such since this is breaking the build of libsanitizer (and so the
+GCC bootstrap[2]) I propose to remove this.
