[FastISel] Lower call instruction with illegal type returned (#180322) Fix issue https://github.com/llvm/llvm-project/issues/179100 When lowering the call instruction with illegal type returned, we should bail out and transfer the lowering to DAG. Otherwise the return value is not promoted to proper type, but DAG would assume it has been promoted. --------- Co-authored-by: Yuanke Luo <ykluo@birentech.com> (cherry picked from commit 41ef3d083a0925cb9c184057f76a0d42ad5680ab)
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.
