Ulrich Weigand	ee84973420	[SystemZ] Use POPCNT instruction on z196 We already exploit a number of instructions specific to z196, but not yet POPCNT. Add support for the population-count facility, MC support for the POPCNT instruction, CodeGen support for using POPCNT, and implement the getPopcntSupport TargetTransformInfo hook. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233689 91177308-0d34-0410-b5e6-96231b3b80d8	2015-03-31 12:56:33 +00:00

[SystemZ] Use POPCNT instruction on z196

We already exploit a number of instructions specific to z196,
but not yet POPCNT.  Add support for the population-count
facility, MC support for the POPCNT instruction, CodeGen
support for using POPCNT, and implement the getPopcntSupport
TargetTransformInfo hook.
