+Subject: [PATCH] GCC: add constexpr to base::ByteSwapUintPtrT and
+ base::ByteSwap
+
+base::internal::EncodedPartitionFreelistEntryPtr::Transform() is
+constexpr. This requires base::ByteSwapUintPtrT() and
+base::ByteSwap() to be constexpr too.

+Subject: [PATCH] GCC: default initialize member in blink::LayoutUnit
+ constructor
+
+Before C++20 the compiler is not required to check that members are
+initialized before use in constexpr constructors. However,
+expressions with undefined behaviour (e.g. due to unitialized data
+members) is prohibited for constexpr. Default initialize to
+value_ to 0 to workaround the problem.
