// File defining fields in the Yap_GLOBAL global structure
|
|
//
|
|
// these fields used to spread all over the place, because they must be used in 3 ways:
|
|
// - they must be defined somewhere
|
|
// - they have an #ifdef to get a shorter name
|
|
// - they must be initialised somewhere
|
|
// - they may be of interest to restore
|
|
//
|
|
// The defs include 4+ components:
|
|
// Type
|
|
// name in structured
|
|
// global name
|
|
// init code (optional)
|
|
// restore code (optional)
|
|
//
|
|
|
|
// Stuff that must be shared by all threads or workers
