This is an optimization pass for GlobalISel generic memory operations.

LLVM_ABI void report_fatal_error(Error Err, bool gen_crash_diag=true)

This struct is a compact representation of a valid (non-zero power of two) alignment.

Define a generic scheduling policy for targets that don't provide their own MachineSchedStrategy.

A region of an MBB for scheduling.
