The popcntw instruction is available whenever the popcntd instruction is available, and performs a separate popcnt on the lower and upper 32-bits. Ignoring the high-order count, this can be used for the 32-bit input case (saving on the explicit zero extension otherwise required to use popcntd). llvm-svn: 178470 |
