Instructions shared between VFP and SIMD so far got rejected after using

	.arch_extension nofp

	* gas/config/tc-arm.c (fpu_vfp_v1xd_or_neon_ext): New.
	(insns) Use fpu_vfp_v1xd_or_neon_ext.

This needs some tests as well, please. In particular, the tests need toensure that the floating-point SIMD versions are correctly disabled forthe case you cite above.
