Meanwhile vmul instruction is supported with Thumb mode. Following snippet
assembles w/o error:

.arch armv8-r 
.syntax unified
.thumb
.fpu fpv5-sp-d16
vmul.f32 s12, s13, s14

Comparing versions 2.32 and 2.33.1 I see that instruction vmul has removed from
"ARM_VARIANT & fpu_vfp_ext_v1xd" in latter one:

 /* Mnemonics shared by Neon and VFP.  */
- nCEF(vmul,     _vmul,    3, (RNSDQ, oRNSDQ, RNSDQ_RNSC), neon_mul),

Does it mean this mnemonic no more supported in ARM mode ?
