// This functionality is implemented by the lib/Bytecode/Reader library.
|
|
// This library is used to read VM bytecode files from an iostream.
|
|
//
|
|
// Note that performance of this library is _crucial_ for performance of the
|
|
// JIT type applications, so we have designed the bytecode format to support
|
|
// quick reading.
