Comment on attachment 192231 [details] proposed patch Nice patch, but: View in context: https://bugs.webkit.org/attachment.cgi?id=192231&action=review > Source/JavaScriptCore/assembler/ARMAssembler.h:1060 > + for (current = firstPageEnd; current < end; current += pageSize()) I think this is incorrect. Are you sure it is not "current + pageSize() < end"?
