--- Comment #15 from Ivo Raisr <iv...@ivosh.net> ---
So the real "culprit" is that on:
amd64/Linux:
guest_amd64_assume_fs_is_const = True
guest_amd64_assume_gs_is_const = True
amd64/Darwin:
guest_amd64_assume_fs_is_const = False
guest_amd64_assume_gs_is_const = True
amd64/Solaris:
guest_amd64_assume_fs_is_const = True
guest_amd64_assume_gs_is_const = True
And amd64 decoder in disInstr_AMD64_WRK(), around lines 32238-32243 fails with:
------------
/* We have a %fs prefix. Reject it if there's no evidence in 'vbi'
that we should accept it. */
if ((pfx & PFX_FS) && !vbi->guest_amd64_assume_fs_is_const)
goto decode_failure;
/* Ditto for %gs prefixes. */
if ((pfx & PFX_GS) && !vbi->guest_amd64_assume_gs_is_const)
goto decode_failure;
-----------
This means that the test cases in cet_nops are probably not valid for all OSes.
Only Linux can have both "fs" and "gs" prefixes, OS X only "gs" and Solaris
only "fs".
I think this could be easily fixed by simple #ifdefery in cet_ops.c.
