Description

6 years ago
The algorithm is, in pseudo asm:
  load $tmp1 <- comp->gcStoreBuffer.bufferCell.pos
  store *$tmp1 <- <addr>
  add $tmp1 + 1
  store comp->gcStoreBuffer.bufferCell.pos <- $tmp1
  if $tmp1 >= comp->gcStoreBuffer.bufferCell.end:
    stubcall comp->gcStoreBuffer.bufferCell.compact

This needs to get inlined into setprop, initprop, some inlines, and a few other places, see the patch in the blocked bug.
