[LLVMdev] [Mips][TargetOptions] How to properly instantiate TargetOptions in MC layer?

[Eric Christopher]

You can't really get there from here is the short answer. You can possible
get MCTargetOptions, but then you need to change all of the constructors
and calls across all of the backends to do this.

I fixed all of the things that are currently in tree - what are you seeing
or what do you need migrated around?

ps. Also, cc'ing me on it would have likely gotten you a faster answer, I
just noticed this while going through email.
