[PATCH] D123814: [compiler-rt][lsan] Update CanBeAHeapPointer for AArch64

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added inline comments.


================
Comment at: compiler-rt/lib/lsan/lsan_common.cpp:255
 #  elif defined(__aarch64__)
-  unsigned runtimeVMA = (MostSignificantSetBitIndex(GET_CURRENT_FRAME()) + 1);
-  return ((p >> runtimeVMA) == 0);
+  // Accept up to 48 bit VMA.
+  return ((p >> 48) == 0);
----------------
I think AArch64 can have up to 52 bit VAs.
