-Configuration files
--------------------
-
-Configuration files group command-line options and allow all of them to be
-specified just by referencing the configuration file. They may be used, for
-example, to collect options required to tune compilation for particular
-target, such as -L, -I, -l, --sysroot, codegen options, etc.
-
-The command line option `--config` can be used to specify configuration
-file in a Clang invocation. For example:
-
-::
-
- clang --config /home/user/cfgs/testing.txt
- clang --config debug.cfg
-
-If the provided argument contains a directory separator, it is considered as
-a file path, and options are read from that file. Otherwise the argument is
-treated as a file name and is searched for sequentially in the directories:
- - user directory,
- - system directory,
- - the directory where Clang executable resides.
-Both user and system directories for configuration files are specified during
-clang build using CMake parameters, CLANG_CONFIG_FILE_USER_DIR and
-CLANG_CONFIG_FILE_SYSTEM_DIR respectively. The first file found is used. It is
-an error if the required file cannot be found.
-
-Another way to specify a configuration file is to encode it in executable name.
-For example, if the Clang executable is named `armv7l-clang` (it may be a
-symbolic link to `clang`), then Clang will search for file `armv7l.cfg` in the
-directory where Clang resides.
-
-If a driver mode is specified in invocation, Clang tries to find a file specific
-for the specified mode. For example, if the executable file is named
-`x86_64-clang-cl`, Clang first looks for `x86_64-cl.cfg` and if it is not found,
-looks for `x86_64.cfg'.
-
-If the command line contains options that effectively change target architecture
-(these are -m32, -EL, and some others) and the configuration file starts with an
-architecture name, Clang tries to load the configuration file for the effective
-architecture. For example, invocation:
-
-::
-
- x86_64-clang -m32 abc.c
-
-causes Clang search for a file `i368.cfg` first, and if no such file is found,
-Clang looks for the file `x86_64.cfg`.
-
-The configuration file consists of command-line options specified on one or
-more lines. Lines composed of whitespace characters only are ignored as well as
-lines in which the first non-blank character is `#`. Long options may be split
-between several lines by a trailing backslash. Here is example of a
-configuration file:
-
-::
-
- # Several options on line
- -c --target=x86_64-unknown-linux-gnu
-
- # Long option split between lines
- -I/usr/lib/gcc/x86_64-linux-gnu/5.4.0/../../../../\
- include/c++/5.4.0
-
- # other config files may be included
- @linux.options
-
-Files included by `@file` directives in configuration files are resolved
-relative to the including file. For example, if a configuration file
-`~/.llvm/target.cfg` contains the directive `@os/linux.opts`, the file
-`linux.opts` is searched for in the directory `~/.llvm/os`.
