Is anything happening on this front?


When aot'ting mcs mono asserts inside emit_method:
                g_warning ("unable to handle jump info %d",
patch_info->type);

It seems like MONO_PATCH_INFO_BB_OVF and MONO_PATCH_INFO_EXC_OVF is only
emitted in the ppc jitter inside EMIT_COND_BRANCH_FLAGS.
And the aot patch code emit_method and mono_aot_load_method doesn't support
patching them.

So i'd really like to get aot running on ppc.
If someone can give me a outline of what should be done to fix this, i am
willing to spend some time on it.
