• File src/runtime/tagged-pointer.m — part of check-in [2fee820b5d] at 2020-09-29 22:21:14 on branch trunk — runtime: Make object_isTaggedPointer() a function

  If it is an inline, changing how tagged pointers work internally would
  break the ABI and require recompiling everything, making future changes
  harder. (user: js, size: 2236) [annotate] [blame] [check-ins using] [more...]
