[MLIR][TableGen] Add genMnemonicAlias field for OpAsm{Type,Attr}Interface (#131504) Since the introduction of `OpAsm{Type,Attr}Interface` (#121187), it is possible to generate alias in AsmPrinter solely from the type/attribute itself without consulting the `OpAsmDialectInterface`. This means the behavior can be put in tablegen file near the type/attribute definition. A common pattern is to just use the type/attr mnemonic as the alias. Previously, like #130479/#130481/#130483, this means adding a default implementation to `extraClassDeclaration` in `LLVM_Attr` base class. However, as attribute definition may override `extraClassDeclaration`, it might be preferred to have a new field in tablegen to specify this behavior. This commit adds a `genMnemonicAlias` field to `AttrOrTypeDef`, when enabled, makes `mlir-tblgen` emit a default implementation of `getAlias` using mnemonic. When `OpAsm{Attr,Type}Interface` is not specified by the user, `tblgen` will automatically add the interface. For users wanting other alias behavior, they can ignore such field and still use `extraClassDeclaration` way.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
