// This file defines the SimpleBBISel class which handles simple basic block
|
|
// instruction selection. If the given BasicBlock is considered "simple", i.e.
|
|
// all operations are supported by the target and their types are legal, it
|
|
// does instruction directly from LLVM BasicBlock to MachineInstr's.
