This adds a GISelValueTrackingPrinterPass that can print the known bits and sign bit of each def in a function. It is built on the new pass manager and so adds a NPM GISelValueTrackingAnalysis, renaming the older class to GISelValueTrackingAnalysisLegacy. The first 2 functions from the AArch64GISelMITest are ported over to an mir test to show it working. It also runs successfully on all files in llvm/test/CodeGen/AArch64/GlobalISel/*.mir that are not invalid. It can hopefully be used to test GlobalISel known bits analysis more directly in common cases, without jumping through the hoops that the C++ tests requires.
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
