It does rely on the remote end running Linux though, which

I could not follow the details of this patch, but since it touches the core of
qemu, are there any tests available to check if these instructions are emulated
correctly?

that's ok, I started from the other end, I'm working on implementing various
boards and MCUs (for the list see
http://gnuarmeclipse.livius.net/blog/qemu/#Supported_boards), but
At first sight VFP4 is sufficient, im focusing on DSP instructions because
FPU is optional on Cortex-M4 (there is Cortex-M4 and Cortex-M4F) so on
cortex_m4_initfn im not adding ARM_FEATURE_VFP4 (right now I dont have the
time to fully check this).
I'd like to point out that i did not implement any

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;

Can you explain what behaviour you're turning on and off
with this f
Im working on the ARM_FEATURE_DSP. I could use some help to add it to the
other CPUs that use it, maybe if someone can
provide me with a list of them i could add the feature.

Im using lm3s6965evb stellaris board, trying to make it "work as an M4", i
would like to separate them, adding an dsp feature (i.e ARM_FEATURE_DSP)
could work? the problem is if this feature is added it has to be set on all
the cpus that use dsp instructions.

For your information, I'm also planning to improve support for the Cortex-M
family in my GNU ARM Eclipse QEMU fork. My first priority is fully supporting
the Cortex-M system pe

Hi, i would like to to add support for cortex-m4 on qemu. Most features of
the Cortex-M3 and M4 are the same with the significant difference that
Cortex-M4 has DSP extensions and optional FPU. Even so, i really need some
pointers for this (im a newbie on qemu devel). I found out that qemu can
