[LLVMdev] Transition to MC

[Jim Grosbach]

Hi Evandro,

There's no such documentation right now. It's on my TODO list, but unfortunately it's not very close to the top right now.

The ARM target migrated to using MC a while back and is probably a reasonable place to look for some guidance. It was done incrementally, not as one big patch, so there's not a specific revision to refer to. However, if you look at the revision history for the ARMAsmPrinter.cpp file and the ARM/InstPrinter directory, the progression should be reasonably clear.
