Tobias Gysi f809eb4db2 [mlir] Argument and result attribute handling during inlining.
The revision adds the handleArgument and handleResult handlers that
allow users of the inlining interface to implement argument and result
conversions that take argument and result attributes into account. The
motivating use cases for this revision are taken from the LLVM dialect
inliner, which has to copy arguments that are marked as byval and that
also has to consider zeroext / signext when converting integers.

All type conversions are currently handled by the
materializeCallConversion hook. It runs before isLegalToInline and
supports only the introduction of a single cast operation since it may
have to rollback. The new handlers run shortly before and after
inlining and cannot fail. As a result, they can introduce more complex
ir such as copying a struct argument. At the moment, the new hooks
cannot be used to perform type conversions since all type conversions
have to be done using the materializeCallConversion. A follow up
revision will either relax this constraint or drop
materializeCallConversion in favor of the new and more flexible
handlers.

The revision also extends the CallableOpInterface to provide access
to the argument and result attributes if available.

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.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.
