URL: https://github.com/llvm/llvm-project/commit/da759dda58a7a1cbdaace26c381e1c3c5c5491ce DIFF: https://github.com/llvm/llvm-project/commit/da759dda58a7a1cbdaace26c381e1c3c5c5491ce.diff LOG: [Clang][Driver] Add option to provide path for multilib's YAML config file (#109640) Since the introduction of the use of a YAML file to configure the selection of multilibs for baremetal, the path for that file has been hardcoded into the clang driver code. This makes it difficult to provide any alternative configurations for multilib and, by consequence, impacts the tetability of any changes related to it - e.g. the existing multilib YAML tests currently rely on creating fake toolchain directories to inject their own configuration files. This change introduces a new command line option to the clang driver, `--multi-lib-config=`, to enable the use of a custom path to be used when loading the multilib YAML config file. It also updates the existing multilib YAML tests to use the new option.
