[lldb-dev] changing register size on the fly?

Some cores can change register sizes on the fly; for example, the Freescale
e6500 can switch between 32 bit and 64 bit mode by writing the CM bit in the
MSR. This causes the upper 32 bits of many 64 bit registers to be ignored.


I'm working with a device that has registers that behave like this. I could
display the larger size, but that's confusing to a user who's working with
the smaller size.


Is there a way to change register size on the fly?
