There are 85 instructions labeled as DSP (all of them thumb2), im just testing on disas_thumb2_insn if the feature is enabled before the instruction is generated.i.e. if (!arm_dc_feature(s, ARM_FEATURE_DSP)) goto illegal_op; Im using DDI0439B_cortex_m4_r0p0_trm - Cortex-M4 Technical Reference Manual (there's s table of dsp instructions on page 33) and this http://www.lpcware.com/system/files/1100969_Cortex-Inst.jpg as reference.
