New Revision: 276786
URL: https://svnweb.freebsd.org/changeset/base/276786

Log:
  Pull in r222292 from upstream llvm trunk (by Weiming Zhao):
  
    [Aarch64] Customer lowering of CTPOP to SIMD should check for NEON
    availability
  
  This ensures llvm's AArch64 backend does not emit floating point
  instructions if they are disabled.
