Hal Finkel	290376dd78	Add the PPC popcntw instruction 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	2013-04-01 15:58:15 +00:00
Hal Finkel	a4d074863a	Add the PPC64 popcntd instruction PPC ISA 2.06 (P7, A2, etc.) has a popcntd instruction. Add this instruction and tell TTI about it so that popcount-loop recognition will know about it. llvm-svn: 178233	2013-03-28 13:29:47 +00:00

Add the PPC popcntw instruction

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).
