[Qemu-devel] [PATCH V2] Target-arm: Add the THUMB_DSP feature

2015-06-14 Thread Aurelio C. Remonda
Created an ARM_FEATURE_THUMB_DSP to be added to any non-M thumb2-compatible CPU that uses DSP instructions. There are 85 DSP instructions (all of them thumb2). On disas_thumb2_insn the DSP feature is tested before the instruction is generated; if it's not enabled then its an illegal op. Signed-off
