Details

There are some redundant operations done in batch atomization during stencil instantiation

  • redundant static string lookup in AtomizeChars (bug 1745664)
  • CanStoreCharsAsLatin1 check done in NewStringCopyN
  • redundant static string lookup TryEmptyOrStaticString in NewStringCopyNDontDeflat
  • repeated AutoAllocInAtomsZone in AllocateNewAtom that can be done in InstantiateMarkedAtoms
  • Zone::isAtomsZone branch in JSLinearString::new_
  • JSString::validateLength operation done in AtomizeAndCopyCharsFromLookup
