The upstream commit: https://reviews.llvm.org/D151590 added a new flag to mark target specific compiler options. The side effect of it was that in cases when -### or -v is used without any input file, clang started emitting an error. It happened like that becasue there is no compilation actions created which could consume/verify these target specific options. This patch changes that error to a warning about unused option in situations when there is no actions and still generates error when there are actions. Fix for https://github.com/llvm/llvm-project/issues/64958 Differential Revision: https://reviews.llvm.org/D159361
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.
