// This file contains the defintions of all DAC variables that the G

//
// This interface has a strict semantic versioning. The following changes require
// a bump to the major version number:
// 1. Changing the type of any of these variables,
// 2. Changing the type layouts of any of the types in gcinterface.dac.h,
// (dac_generation, dac_heap_segment, dac_finalize_queue)
// 3. Changing the semantic meaning of any of these variables, such that the DAC's
// use of them is no longer correct,
//
// The following change requires a bump to the minor version number:
// 1. Adding additional DAC variables.
//
// Minor version mismatches are tolerated by the DAC, at the risk of a possibly
// degraded debugging experience.
// Major version mismatches are not tolerated by the DAC and will be rejected upon load.
