library vm.bytecode.dbc;
// List of changes from original DBC (described in runtime/vm/constants_dbc.h):
//
// 1. StoreFieldTOS, LoadFieldTOS instructions:
// D = index of constant pool entry with FieldOffset,
// TypeArgumentsFieldOffset or ConstantContextOffset tags
// (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
