This hashing scheme has been useful out of tree, and I want to start experimenting with it. Specifically I want to experiment on the MIRVRegNamer, MIRCanononicalizer, and eventually the MachineOutliner. This diff is a first step, that optionally brings stable hashing to the MIRVRegNamer (and as a result, the MIRCanonicalizer). We've tested this hashing scheme on a lot of MachineOperand types that llvm::hash_value can not handle in a stable manner. This stable hashing was also the basis for "Global Machine Outliner for ThinLTO" in EuroLLVM 2020 http://llvm.org/devmtg/2020-04/talks.html#TechTalk_58 Credits: Kyungwoo Lee, Nikolai Tillmann Differential Revision: https://reviews.llvm.org/D86952 |

This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
