[mlir][bufferization] Add support for recursive function calls (#114003) This commit adds support for recursive function calls to One-Shot Bufferize. The analysis does not support recursive function calls. The function body itself can be analyzed, but we cannot make any assumptions about the aliasing relation between function result and function arguments. Similarly, when looking at a `call` op, we do not know whether the operands will bufferize to a memory read/write. In the absence of such information, we have to conservatively assume that they do. This commit is in preparation of removing the deprecated `func-bufferize` pass. That pass can bufferize recursive functions.
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.
