| |
| // List of changes from original DBC (described in runtime/vm/constants_dbc.h): |
| // |
| // 1. StoreFieldTOS, LoadFieldTOS instructions: |
| // D = index of constant pool entry with InstanceField tag. |
| // (instead of field offset in words). |
| // |
| // 2. EntryOptional instruction is revived in order to re-shuffle optional |
| // parameters. This DBC instruction was removed at |
| // https://github.com/dart-lang/sdk/commit/cf1de7d46cd88e204380e8f96a993439be56b24c |
| // |
| // 3. NativeCall instruction is modified to have 'D' format and take 1 argument: |
| // D = index of NativeEntry constant pool entry |
| // |
| // 4. JumpIfNoAsserts instruction is added. This instruction jumps to the given |
| // target if assertions are not enabled. It has the same format as Jump |
| // instruction. |
| // |
| // 5. StoreContextParent stores context SP[0] into `parent` field of context SP[-1]. |
| // |
| // 6. LoadContextParent loads parent from context SP[0]. |
| // |
| // 7. StoreContextVar stores value SP[0] into context SP[-1] at index D. |
| // |
| // 8. LoadContextVar loads value from context SP[0] at index D. |
| // |
| // 9. LoadTypeArgumentsField loads instantiator type arguments from an |
| // instance SP[0]. |
| // D = index of TypeArgumentsField constant pool entry corresponding |
| // to an instance's class. |
| // |
| // 10. InstanceCall1 and InstanceCall2 instructions are superseded by |
| // InstanceCall which works for any number of checked arguments. |
| // |
| // 11. EntryFixed instruction works like Entry. In addition, it checks number |
| // of fixed arguments. |
| // |
| // 12. JumpIfNotZeroTypeArgs instruction jumps if number of passed |
| // function type arguments is not zero. |
| // |
| // 13. PushNull, PushTrue, PushFalse, PushInt instructions added. |
