[LLD] [MinGW] Recognize the -rpath option (#102886) GNU ld silently accepts the -rpath option for Windows targets, as a no-op. This has lead to some build systems (and users) passing this option while building for Windows/MinGW, even if Windows doesn't have any concept like rpath. Older versions of Conan did include -rpath in the pkg-config files it generated, see e.g. https://github.com/conan-io/conan/blob/17c58f0c61931f9de218ac571cd97a8e0befa68e/conans/client/generators/pkg_config.py#L104-L114 and https://github.com/conan-io/conan/blob/17c58f0c61931f9de218ac571cd97a8e0befa68e/conans/client/build/compiler_flags.py#L26-L34 - and see https://github.com/mstorsjo/llvm-mingw/issues/300 for user reports about this issue. Recognize the option in LLD for MinGW targets, to improve drop-in compatibility compared to GNU ld, but produce a warning to alert users that the option really has no effect for these targets.
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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
