It was introduced in https://bugs.webkit.org/show_bug.cgi?id=202832, and Daniel Bates notified me of a bug in it. More precisely, it calls ldr<16>, which calls CHECK_DATASIZE which in turns does an ASSERT(16 == 32 || 16 == 64); I am still trying to see if I can just remove the assert (which looks plain wrong), or if there is a more serious problem here. <rdar://problem/57297184> REGRESSION (r252422) CHECK_DATASIZE() fails loading docs.google.com
