Comment on attachment 271534 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=271534&action=review > Source/JavaScriptCore/b3/air/AirOpcode.opcodes:400 > + arm64: BitImm64, Tmp, Tmp I don't understand this. 1) Does it really support 64-bit immediates? 2) Why can't we use Imm64 in that case?
