How does one check if the bit has been explicitly set? It was not obvious to

me, which is why I took a similar approach to a patch I found for another
CPU target. If it is possible to change the default without adding another
flag then that is obviously better and I will update my patch.


Or you can just change the default target_flags, supposedly with
TargetVariable
int target_flags = MASK_USER_MODE
in the opt file, there are really many possibilities.

Thanks! I went with your suggestion in the previous mail and removed thenew -msv-mode option and inversed the user mode mask.


Best regards,
Daniel Cederman
