Detailed Description

This file contains both AMDGPU target machine and the CodeGen pass builder.

The AMDGPU target machine contains all of the hardware specific information needed to emit code for SI+ GPUs in the legacy pass manager pipeline. The CodeGen pass builder handles the pass pipeline for new pass manager.
