Subject: 	* gas/config/tc-arm.c (NEON_ENC_TAB): Add entries for VSEL. 
 (NEON_ENC_FPV8_): New define. 	(do_vfp_nsyn_fpv8): New function. 
 (do_vsel): Likewise. 	(insns): Add VSEL instructions. 	*
 gas/testsuite/gas/arm/armv8-a+fp.d: New testcase. 	*
 gas/testsuite/gas/arm/armv8-a+fp.s: Likewise. 	* opcodes/arm-dis.c
 (coprocessor_opcodes): Add VSEL. 	(print_insn_coprocessor): Add new %<>c
 bitfield format 	specifier.
