  "message": "Optimize SwissMap iteration by another 5-10% for ARM\n\nhttps://pastebin.com/fDvgWgHe\n\nAfter having a chat with Dougall Johnson (https://twitter.com/dougallj/status/1534213050944802816), we realized that __clzll works with zero arguments per documentation:\n\nhttps://developer.arm.com/documentation/101028/0009/Data-processing-intrinsics\n\n```\nReturns the number of leading zero bits in x. When x is zero it returns the argument width, i.e. 32 or 64.\n```\n\nCodegen improves https://godbolt.org/z/ebadf717Y\n\nThus we can use a little bit different construction not involving CLS but using more understandable CLZ and removing some operations.\n\nPiperOrigin-RevId: 453879080\nChange-Id: Ie2d7f834f63364d7bd50dd6a682c107985f21942\n",
