 ## Object representation
 
-Object pointers refer either to immediate objects or heap objects, distinguished by a tag in the low bits of the pointer. The Dart VM has only one kind of immediate object, Smis (small integers), whose pointers have a tag of 0. Heap objects have a pointer tag of 1. The upper bits of a Smi pointer are its value, and the upper bits of a heap object pointer are the most signficant bits of its address (the least significant bit is always 0 because heap objects always have greater than 2-byte alignment).
+Object pointers refer either to immediate objects or heap objects, distinguished by a tag in the low bits of the pointer. The Dart VM has only one kind of immediate object, Smis (small integers), whose pointers have a tag of 0. Heap objects have a pointer tag of 1. The upper bits of a Smi pointer are its value, and the upper bits of a heap object pointer are the most significant bits of its address (the least significant bit is always 0 because heap objects always have greater than 2-byte alignment).
 
 A tag of 0 allows many operations to be performed on Smis without untagging and retagging. It also allows hiding aligned addresses to the C heap from the GC.
 
 A tag of 1 has no penalty on heap object access because removing the tag can be folded into the offset used by load and store instructions.
 
-Heap objects are always allocated in double-word increments. Objects in old-space are kept at double-word alignment (address % double-word == 0), and objects in new-space are kept offset from double-word alignment (address % double-word == word). This allows checking an object's age without comparing to a boundry address, avoiding restrictions on heap placement and avoiding loading the boundry from thread-local storage. Additionally, the scavenger can quickly skip over both immediates and old objects with a single branch.

 A GC is said to be "precise" if when a collection happens it knows exactly what is and is not a pointer into the heap. For example, in compiled Dart code the VM tracks which stack slots contain object pointers and which contain unboxed values. This is opposed to a "conservative" collector that considers any pointer-sized value might be a pointer into the heap, though it might just be an unboxed value.
 
-In a "moving" GC, the address of an object might change, requiring pointers to that object to be updated. In the Dart VM, objects can move during a scavenge or a compaction. A moving GC must be a precise GC: if a conservative GC updates a value that is not guarenteed to be a pointer, it will corrupt execution when the value was not in fact a pointer.

A moving GC must be a precise GC: if a conservative GC updates a value that is not guaranteed to be a pointer, it will corrupt execution when the value was not in fact a pointer.
 
 The VM does not know which stack slots, globals or object fields in foreign languages contain pointers into the Dart heap, including the VM's own runtime implemented in C++. For the GC to remain precise, foreign languages reference Dart objects indirectly through "handles". Handles can be thought of as pointers to pointers. They are allocated from the VM, and the GC will visit (and possibly update) the pointers contained in handles during collections.
