+// Macro list of all constants that differ based on whether the architecture is
+// 32-bit or 64-bit. They are used to allow the target architecture to differ
+// from the host, like this:
+// 1) The macros correspond to constants defined throughout the VM that are
+// sized based on the *host* architecture.
+// 2) offsets_extractor.cc prints these values to runtime_offsets_extracted.h,
+// for both 32 and 64 bit architectures.
+// 3) runtime_api.h presents the runtime_offsets_extracted.h constants in a way
+// designed to look like the original constants from 1), but now namespaced
+// to dart::compiler::target, and sized based on the *target* architecture.
+// 4) Users of the constants from 1) can now just add the namespace from 3) to
+// get all their constants sized based on the target rather than the host.
+
+// FIELD(Class, Name) Offset of a field within a class.

+// ARRAY_STRUCTFIELD(Class, Name, Element, Field) Offset of a field within a
+// struct in an array of that struct, relative to the start of the array.
+// SIZEOF(Class, Name, What) Size of an object.
