// 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(Class, Name) Offset of the first element and the size of the elements
//     in an array of this 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.
// RANGE(Class, Name, Type, First, Last, Filter) An array of offsets generated
//     by passing a value of the given Type in the range from First to Last to
//     Class::Name() if Filter returns true for that value.
// CONSTANT(Class, Name) Miscellaneous constant.
// PRECOMP_NO_CHECK(Code) Don't check this offset in the precompiled runtime.
