New Revision: 318135
URL: https://svnweb.freebsd.org/changeset/base/318135

Log:
  Fix parsing of 'vmov Q<n>.F32,Q<n>.F32' instruction.
  
  parse_qfloat_immediate() accidentaly parses register with size
  qualifier as immediate constant (It takes '<n>.' substring as
  valid floating point constant).
  
  Due to this, slightly reorder cases in parse_neon_mov() and move parsing of
  vmov with immediate constant to last place.
  
  MFC after:	2 weeks
