| // 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. |
