But make -** sure nothing invokes the GC inbetween. -** - The target and the source are the same object (self-reference). -** - The target already contains the object (e.g. moving elements around). -** -** The most common case is a store to a stack slot. All other cases where -** a barrier has been omitted are annotated with a NOBARRIER comment. -** -** The same logic applies for stores to table slots (array part or hash -** part). ALL uses of lj_tab_set* require a barrier for the stored value -** *and* the stored key, based on the above rules. In practice this means -** a barrier is needed if *either* of the key or value are a GC object. -** -** It's ok to LEAVE OUT the write barrier in the following special cases: -** - The stored value is nil. The key doesn't matter because it's either -** not resurrected or lj_tab_newkey() will take care of the key barrier. -** - The key doesn't matter if the *previously* stored value is guaranteed -** to be non-nil (because the key is kept alive in the table). -** - The key doesn't matter if it's guaranteed not to be part of the table, -** since lj_tab_newkey() takes care of the key barrier. This applies -** trivially to new tables, but watch out for resurrected keys. Storing -** a nil value leaves the key in the table! -** -** In case of doubt use lj_gc_anybarriert() as it's rather cheap. It's used -** by the interpreter for all table stores. -** -** Note: In contrast to Lua's GC, LuaJIT's GC does *not* specially mark -** dead keys in tables. The reference is left in, but it's guaranteed to -** be never dereferenced as long as the value is nil. It's ok if the key is -** freed or if any object subsequently gets the same address. -** -** Not destroying dead keys helps to keep key hash slots stable. This avoids -** specialization back-off for HREFK when a value flips between nil and -** non-nil and the GC gets in the way. It also allows safely hoisting -** HREF/HREFK across GC steps. Dead keys are only removed if a table is -** resized (i.e. by NEWREF) and xREF must not be CSEd across a resize. -** -** The trade-off is that a write barrier for tables must take the key into -** account, too. Implicitly resurrecting the key by storing a non-nil value -** may invalidate the incremental GC invariant. -*/ - -/* -- Common type definitions --------------------------------------------- */ - -/* Types for handling bytecodes.
