In the original case, the third call to `getCheaperNegatedExpression` deletes the SDNode returned by the first call. Similar to 74e6030bcbcc8e628f9a99a424342a0c656456f9, this patch uses `HandleSDNodes` to prevent nodes from being deleted by subsequent calls. Closes https://github.com/llvm/llvm-project/issues/138944. (cherry picked from commit 143cce72b1f50bc37363315793b80ae92d2b0ae3)
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.
