[LLVMdev] Heads up: Local register allocator going away

llvm/lib/CodeGen/RegisterScavenging.cpp:196: void
llvm::RegScavenger::forward(): Assertion `SubUsed && "Using an undefined
register!"' failed.
In r103685 ("More asserts around physreg uses") the error changed to:

[LLVMdev] Heads up: Local register allocator going away
I just changed the default register allocator for -O0 builds to the fast allocator.
This means that the local register allocator is not used anymore, and since it does more or less the same as the fast allocator, there is no reason to keep it around.
I am going to delete it in a week or two.
If you are using the local register allocator, please try switching to the fast allocator and report any
