Count leading sign bits
Web32-bit signed result that is sign-extended to XLEN. Bitmanip instructions with the suffix .uw have one operand that is an unsigned 32-bit value that is extracted from the least significant 32 bits of the specified register. Other than that, these perform full XLEN operations. ... clzw rd, rs Count leading zero bits in word ...

WebPlatform-specific intrinsics for the `aarch64` platform. Bitwise Select instructions. This instruction sets each bit in the destination SIMD&FP register to the corresponding bit from the first source SIMD&FP register when the original destination bit was 1, otherwise from the second source SIMD&FP register. WebThe count trailing zeros operation would return 3, while the count leading zeros operation returns 16. The count leading zeros operation depends on the word size: if this 32-bit …
