-Introduction
-============
-
-LLVMC is a generic compiler driver, designed to be customizable and
-extensible. It plays the same role for LLVM as the ``gcc`` program does for
-GCC - LLVMC's job is essentially to transform a set of input files into a set of
-targets depending on configuration rules and user options. What makes LLVMC
-different is that these transformation rules are completely customizable - in
-fact, LLVMC knows nothing about the specifics of transformation (even the
-command-line options are mostly not hard-coded) and regards the transformation
-structure as an abstract graph. The structure of this graph is described in
-high-level TableGen code, from which an efficient C++ representation is
-automatically derived. This makes it possible to adapt LLVMC for other
-purposes - for example, as a build tool for game resources.
-
-Because LLVMC employs TableGen_ as its configuration language, you
-need to be familiar with it to customize LLVMC.
-
-.. _TableGen: http://llvm.org/docs/TableGenFundamentals.html
-
-
-Compiling with ``llvmc``
-========================
-
-LLVMC tries hard to be as compatible with ``gcc`` as possible,
-although there are some small differences. Most of the time, however,
-you shouldn't be able to notice them::
-
-     $ # This works as expected:
-     $ llvmc -O3 -Wall hello.cpp
-     $ ./a.out
-     hello
-
-One nice feature of LLVMC is that one doesn't have to distinguish between
-different compilers for different languages (think ``g++`` vs.  ``gcc``) - the
-right toolchain is chosen automatically based on input language names (which
-are, in turn, determined from file extensions). If you want to force files
-ending with ".c" to compile as C++, use the ``-x`` option, just like you would
-do it with ``gcc``::
-
-      $ # hello.c is really a C++ file
-      $ llvmc -x c++ hello.c
-      $ ./a.out
-      hello
-
-On the other hand, when using LLVMC as a linker to combine several C++
-object files you should provide the ``--linker`` option since it's
-impossible for LLVMC to choose the right linker in that case::
-
-    $ llvmc -c hello.cpp
-    $ llvmc hello.o
-    [A lot of link-time errors skipped]
-    $ llvmc --linker=c++ hello.o
-    $ ./a.out
-    hello
-
-By default, LLVMC uses ``llvm-gcc`` to compile the source code. It is also
-possible to choose the ``clang`` compiler with the ``-clang`` option.
-
-
-Predefined options
-==================
-
-LLVMC has some built-in options that can't be overridden in the TableGen code:
-
-* ``-o FILE`` - Output file name.
-
-* ``-x LANGUAGE`` - Specify the language of the following input files
-  until the next -x option.
-
-* ``-v`` - Enable verbose mode, i.e. print out all executed commands.
-
-* ``--save-temps`` - Write temporary files to the current directory and do not
-  delete them on exit. This option can also take an argument: the
-  ``--save-temps=obj`` switch will write files into the directory specified with
-  the ``-o`` option. The ``--save-temps=cwd`` and ``--save-temps`` switches are
-  both synonyms for the default behaviour.
-
-* ``--temp-dir DIRECTORY`` - Store temporary files in the given directory. This
-  directory is deleted on exit unless ``--save-temps`` is specified. If
-  ``--save-temps=obj`` is also specified, ``--temp-dir`` is given the
-  precedence.
-
-* ``--check-graph`` - Check the compilation for common errors like mismatched
-  output/input language names, multiple default edges and cycles. Exit with code
-  zero if no errors were found, and return the number of found errors
-  otherwise. Hidden option, useful for debugging.
-
-* ``--view-graph`` - Show a graphical representation of the compilation graph
-  and exit. Requires that you have ``dot`` and ``gv`` programs installed. Hidden
-  option, useful for debugging.
-
-* ``--write-graph`` - Write a ``compilation-graph.dot`` file in the current
-  directory with the compilation graph description in Graphviz format (identical
-  to the file used by the ``--view-graph`` option). The ``-o`` option can be
-  used to set the output file name. Hidden option, useful for debugging.
-
-* ``--help``, ``--help-hidden``, ``--version`` - These options have
-  their standard meaning.
-
-Compiling LLVMC-based drivers
-=============================
-
-It's easiest to start working on your own LLVMC driver by copying the skeleton
-project which lives under ``$LLVMC_DIR/examples/Skeleton``::
-
-   $ cd $LLVMC_DIR/examples
-   $ cp -r Skeleton MyDriver
-   $ cd MyDriver
-   $ ls
-   AutoGenerated.td  Hooks.cpp  Main.cpp  Makefile
-
-As you can see, our basic driver consists of only three files (not counting the
-build script). ``AutoGenerated.td`` contains TableGen description of the
-compilation graph; its format is documented in the following
-sections. ``Hooks.cpp`` is an empty file that should be used for hook
-definitions (see `below`__). ``Main.cpp`` is just a helper used to compile the
-auto-generated C++ code produced from TableGen source.
-
-__ hooks_
-
-The first thing that you should do is to change the ``LLVMC_BASED_DRIVER``
-variable in the ``Makefile``::
-
-   LLVMC_BASED_DRIVER=MyDriver
-
-It can also be a good idea to put your TableGen code into a file with a less
-generic name::
-
-   $ touch MyDriver.td
-   $ vim AutoGenerated.td
-   [...]
-   include "MyDriver.td"
-
-If you have more than one TableGen source file, they all should be included from
-``AutoGenerated.td``, since this file is used by the build system to generate
-C++ code.
-
-To build your driver, just ``cd`` to its source directory and run ``make``. The
-resulting executable will be put into ``$LLVM_OBJ_DIR/$(BuildMode)/bin``.
-
-If you're compiling LLVM with different source and object directories, then you
-must perform the following additional steps before running ``make``::
-
-    # LLVMC_SRC_DIR = $LLVM_SRC_DIR/tools/llvmc/
-    # LLVMC_OBJ_DIR = $LLVM_OBJ_DIR/tools/llvmc/
-    $ mkdir $LLVMC_OBJ_DIR/examples/MyDriver/
-    $ cp $LLVMC_SRC_DIR/examples/MyDriver/Makefile \
-      $LLVMC_OBJ_DIR/examples/MyDriver/
-    $ cd $LLVMC_OBJ_DIR/examples/MyDriver
-    $ make
-
-
-Customizing LLVMC: the compilation graph
-========================================
-
-Each TableGen configuration file should include the common definitions::
-
-   include "llvm/CompilerDriver/Common.td"
-
-Internally, LLVMC stores information about possible source transformations in
-form of a graph. Nodes in this graph represent tools, and edges between two
-nodes represent a transformation path. A special "root" node is used to mark
-entry points for the transformations. LLVMC also assigns a weight to each edge
-(more on this later) to choose between several alternative edges.
-
-The definition of the compilation graph (see file ``llvmc/src/Base.td`` for an
-example) is just a list of edges::
-
-    def CompilationGraph : CompilationGraph<[
-        Edge<"root", "llvm_gcc_c">,
-        Edge<"root", "llvm_gcc_assembler">,
-        ...
-
-        Edge<"llvm_gcc_c", "llc">,
-        Edge<"llvm_gcc_cpp", "llc">,
-        ...
-
-        OptionalEdge<"llvm_gcc_c", "opt", (case (switch_on "opt"),
-                                          (inc_weight))>,
-        OptionalEdge<"llvm_gcc_cpp", "opt", (case (switch_on "opt"),
-                                                  (inc_weight))>,
-        ...
-
-        OptionalEdge<"llvm_gcc_assembler", "llvm_gcc_cpp_linker",
-            (case (input_languages_contain "c++"), (inc_weight),
-                  (or (parameter_equals "linker", "g++"),
-                      (parameter_equals "linker", "c++")), (inc_weight))>,
-        ...
-
-        ]>;
-
-As you can see, the edges can be either default or optional, where optional
-edges are differentiated by an additional ``case`` expression used to calculate
-the weight of this edge. Notice also that we refer to tools via their names (as
-strings). This makes it possible to add edges to an existing compilation graph
-without having to know about all tool definitions used in the graph.
-
-The default edges are assigned a weight of 1, and optional edges get a weight of
-0 + 2*N where N is the number of tests that evaluated to true in the ``case``
-expression. It is also possible to provide an integer parameter to
-``inc_weight`` and ``dec_weight`` - in this case, the weight is increased (or
-decreased) by the provided value instead of the default 2. Default weight of an
-optional edge can be changed by using the ``default`` clause of the ``case``
-construct.
-
-When passing an input file through the graph, LLVMC picks the edge with the
-maximum weight. To avoid ambiguity, there should be only one default edge
-between two nodes (with the exception of the root node, which gets a special
-treatment - there you are allowed to specify one default edge *per language*).
-
-When multiple compilation graphs are defined, they are merged together. Multiple
-edges with the same end nodes are not allowed (i.e. the graph is not a
-multigraph), and will lead to a compile-time error.
-
-To get a visual representation of the compilation graph (useful for debugging),
-run ``llvmc --view-graph``. You will need ``dot`` and ``gsview`` installed for
-this to work properly.
-
-Describing options
-==================
-
-Command-line options supported by the driver are defined by using an
-``OptionList``::
-
-    def Options : OptionList<[
-    (switch_option "E", (help "Help string")),
-    (alias_option "quiet", "q")
-    ...
-    ]>;
-
-As you can see, the option list is just a list of DAGs, where each DAG is an
-option description consisting of the option name and some properties. More than
-one option list can be defined (they are all merged together in the end), which
-can be handy if one wants to separate option groups syntactically.
-
-* Possible option types:
-
-   - ``switch_option`` - a simple boolean switch without arguments, for example
-     ``-O2`` or ``-time``. At most one occurrence is allowed by default.
-
-   - ``parameter_option`` - option that takes one argument, for example
-     ``-std=c99``. It is also allowed to use spaces instead of the equality
-     sign: ``-std c99``. At most one occurrence is allowed.
-
-   - ``parameter_list_option`` - same as the above, but more than one option
-     occurrence is allowed.
-
-   - ``prefix_option`` - same as the parameter_option, but the option name and
-     argument do not have to be separated. Example: ``-ofile``. This can be also
-     specified as ``-o file``; however, ``-o=file`` will be parsed incorrectly
-     (``=file`` will be interpreted as option value). At most one occurrence is
-     allowed.
-
-   - ``prefix_list_option`` - same as the above, but more than one occurrence of
-     the option is allowed; example: ``-lm -lpthread``.
-
-   - ``alias_option`` - a special option type for creating aliases. Unlike other
-     option types, aliases are not allowed to have any properties besides the
-     aliased option name.
-     Usage example: ``(alias_option "preprocess", "E")``
-
-   - ``switch_list_option`` - like ``switch_option`` with the ``zero_or_more``
-     property, but remembers how many times the switch was turned on. Useful
-     mostly for forwarding. Example: when ``-foo`` is a switch option (with the
-     ``zero_or_more`` property), the command ``driver -foo -foo`` is forwarded
-     as ``some-tool -foo``, but when ``-foo`` is a switch list, the same command
-     is forwarded as ``some-tool -foo -foo``.
-
-
-* Possible option properties:
-
-   - ``help`` - help string associated with this option. Used for ``--help``
-     output.
-
-   - ``required`` - this option must be specified exactly once (or, in case of
-     the list options without the ``multi_val`` property, at least
-     once). Incompatible with ``optional`` and ``one_or_more``.
-
-   - ``optional`` - the option can be specified either zero times or exactly
-     once. The default for switch options. Useful only for list options in
-     conjunction with ``multi_val``. Incompatible with ``required``,
-     ``zero_or_more`` and ``one_or_more``.
-
-   - ``one_or_more`` - the option must be specified at least once. Can be useful
-     to allow switch options be both obligatory and be specified multiple
-     times. For list options is useful only in conjunction with ``multi_val``;
-     for ordinary it is synonymous with ``required``. Incompatible with
-     ``required``, ``optional`` and ``zero_or_more``.
-
-   - ``zero_or_more`` - the option can be specified zero or more times. Useful
-     to allow a single switch option to be specified more than
-     once. Incompatible with ``required``, ``optional`` and ``one_or_more``.
-
-   - ``hidden`` - the description of this option will not appear in
-     the ``--help`` output (but will appear in the ``--help-hidden``
-     output).
-
-   - ``really_hidden`` - the option will not be mentioned in any help
-     output.
-
-   - ``comma_separated`` - Indicates that any commas specified for an option's
-     value should be used to split the value up into multiple values for the
-     option. This property is valid only for list options. In conjunction with
-     ``forward_value`` can be used to implement option forwarding in style of
-     gcc's ``-Wa,``.
-
-   - ``multi_val n`` - this option takes *n* arguments (can be useful in some
-     special cases). Usage example: ``(parameter_list_option "foo", (multi_val
-     3))``; the command-line syntax is '-foo a b c'. Only list options can have
-     this attribute; you can, however, use the ``one_or_more``, ``optional``
-     and ``required`` properties.
-
-   - ``init`` - this option has a default value, either a string (if it is a
-     parameter), or a boolean (if it is a switch; as in C++, boolean constants
-     are called ``true`` and ``false``). List options can't have ``init``
-     attribute.
-     Usage examples: ``(switch_option "foo", (init true))``; ``(prefix_option
-     "bar", (init "baz"))``.
-
-.. _case:
-
-Conditional evaluation
-======================
-
-The 'case' construct is the main means by which programmability is achieved in
-LLVMC. It can be used to calculate edge weights, program actions and modify the
-shell commands to be executed. The 'case' expression is designed after the
-similarly-named construct in functional languages and takes the form ``(case
-(test_1), statement_1, (test_2), statement_2, ... (test_N), statement_N)``. The
-statements are evaluated only if the corresponding tests evaluate to true.
-
-Examples::
-
-    // Edge weight calculation
-
-    // Increases edge weight by 5 if "-A" is provided on the
-    // command-line, and by 5 more if "-B" is also provided.
-    (case
-        (switch_on "A"), (inc_weight 5),
-        (switch_on "B"), (inc_weight 5))
-
-
-    // Tool command line specification
-
-    // Evaluates to "cmdline1" if the option "-A" is provided on the
-    // command line; to "cmdline2" if "-B" is provided;
-    // otherwise to "cmdline3".
-
-    (case
-        (switch_on "A"), "cmdline1",
-        (switch_on "B"), "cmdline2",
-        (default), "cmdline3")
-
-Note the slight difference in 'case' expression handling in contexts of edge
-weights and command line specification - in the second example the value of the
-``"B"`` switch is never checked when switch ``"A"`` is enabled, and the whole
-expression always evaluates to ``"cmdline1"`` in that case.
-
-Case expressions can also be nested, i.e. the following is legal::
-
-    (case (switch_on "E"), (case (switch_on "o"), ..., (default), ...)
-          (default), ...)
-
-You should, however, try to avoid doing that because it hurts readability. It is
-usually better to split tool descriptions and/or use TableGen inheritance
-instead.
-
-* Possible tests are:
-
-  - ``switch_on`` - Returns true if a given command-line switch is provided by
-    the user. Can be given multiple arguments, in that case ``(switch_on "foo",
-    "bar", "baz")`` is equivalent to ``(and (switch_on "foo"), (switch_on
-    "bar"), (switch_on "baz"))``.
-    Example: ``(switch_on "opt")``.
-
-  - ``any_switch_on`` - Given a number of switch options, returns true if any of
-    the switches is turned on.
-    Example: ``(any_switch_on "foo", "bar", "baz")`` is equivalent to ``(or
-    (switch_on "foo"), (switch_on "bar"), (switch_on "baz"))``.
-
-  - ``parameter_equals`` - Returns true if a command-line parameter (first
-    argument) equals a given value (second argument).
-    Example: ``(parameter_equals "W", "all")``.
-
-  - ``element_in_list`` - Returns true if a command-line parameter list (first
-    argument) contains a given value (second argument).
-    Example: ``(element_in_list "l", "pthread")``.
-
-  - ``input_languages_contain`` - Returns true if a given language
-    belongs to the current input language set.
-    Example: ``(input_languages_contain "c++")``.
-
-  - ``in_language`` - Evaluates to true if the input file language is equal to
-    the argument. At the moment works only with ``command`` and ``actions`` (on
-    non-join nodes).
-    Example: ``(in_language "c++")``.
-
-  - ``not_empty`` - Returns true if a given option (which should be either a
-    parameter or a parameter list) is set by the user. Like ``switch_on``, can
-    be also given multiple arguments.
-    Examples: ``(not_empty "o")``, ``(not_empty "o", "l")``.
-
-  - ``any_not_empty`` - Returns true if ``not_empty`` returns true for any of
-    the provided options.
-    Example: ``(any_not_empty "foo", "bar", "baz")`` is equivalent to ``(or
-    (not_empty "foo"), (not_empty "bar"), (not_empty "baz"))``.
-
-  - ``empty`` - The opposite of ``not_empty``. Equivalent to ``(not (not_empty
-    X))``. Can be given multiple arguments.
-
-  - ``any_not_empty`` - Returns true if ``not_empty`` returns true for any of
-    the provided options.
-    Example: ``(any_empty "foo", "bar", "baz")`` is equivalent to ``(or
-    (not_empty "foo"), (not_empty "bar"), (not_empty "baz"))``.
-
-  - ``single_input_file`` - Returns true if there was only one input file
-    provided on the command-line. Used without arguments:
-    ``(single_input_file)``.
-
-  - ``multiple_input_files`` - Equivalent to ``(not (single_input_file))`` (the
-    case of zero input files is considered an error).
-
-  - ``default`` - Always evaluates to true. Should always be the last
-    test in the ``case`` expression.
-
-  - ``and`` - A standard logical combinator that returns true iff all of
-    its arguments return true. Used like this: ``(and (test1), (test2),
-    ... (testN))``. Nesting of ``and`` and ``or`` is allowed, but not
-    encouraged.
-
-  - ``or`` - A logical combinator that returns true iff any of its arguments
-    return true.
-    Example: ``(or (test1), (test2), ... (testN))``.
-
-  - ``not`` - Standard unary logical combinator that negates its
-    argument.
-    Example: ``(not (or (test1), (test2), ... (testN)))``.
-
-
-Writing a tool description
-==========================
-
-As was said earlier, nodes in the compilation graph represent tools, which are
-described separately. A tool definition looks like this (taken from the
-``llvmc/src/Base.td`` file)::
-
-  def llvm_gcc_cpp : Tool<[
-      (in_language "c++"),
-      (out_language "llvm-assembler"),
-      (output_suffix "bc"),
-      (command "llvm-g++ -c -emit-llvm"),
-      (sink)
-      ]>;
-
-This defines a new tool called ``llvm_gcc_cpp``, which is an alias for
-``llvm-g++``. As you can see, a tool definition is just a list of properties;
-most of them should be self-explanatory. The ``sink`` property means that this
-tool should be passed all command-line options that aren't mentioned in the
-option list.
-
-The complete list of all currently implemented tool properties follows.
-
-* Possible tool properties:
-
-  - ``in_language`` - input language name. Can be given multiple arguments, in
-    case the tool supports multiple input languages. Used for typechecking and
-    mapping file extensions to tools.
-
-  - ``out_language`` - output language name. Multiple output languages are
-    allowed. Used for typechecking the compilation graph.
-
-  - ``output_suffix`` - output file suffix. Can also be changed dynamically, see
-    documentation on `actions`__.
-
-__ actions_
-
-  - ``command`` - the actual command used to run the tool. You can use output
-    redirection with ``>``, hook invocations (``$CALL``), environment variables
-    (via ``$ENV``) and the ``case`` construct.
-
-  - ``join`` - this tool is a "join node" in the graph, i.e. it gets a list of
-    input files and joins them together. Used for linkers.
-
-  - ``sink`` - all command-line options that are not handled by other tools are
-    passed to this tool.
-
-  - ``actions`` - A single big ``case`` expression that specifies how this tool
-    reacts on command-line options (described in more detail `below`__).
-
-__ actions_
-
-  - ``out_file_option``, ``in_file_option`` - Options appended to the
-    ``command`` string to designate output and input files. Default values are
-    ``"-o"`` and ``""``, respectively.
-
-.. _actions:
-
-Actions
--------
-
-A tool often needs to react to command-line options, and this is precisely what
-the ``actions`` property is for. The next example illustrates this feature::
-
-  def llvm_gcc_linker : Tool<[
-      (in_language "object-code"),
-      (out_language "executable"),
-      (output_suffix "out"),
-      (command "llvm-gcc"),
-      (join),
-      (actions (case (not_empty "L"), (forward "L"),
-                     (not_empty "l"), (forward "l"),
-                     (not_empty "dummy"),
-                               [(append_cmd "-dummy1"), (append_cmd "-dummy2")])
-      ]>;
-
-The ``actions`` tool property is implemented on top of the omnipresent ``case``
-expression. It associates one or more different *actions* with given
-conditions - in the example, the actions are ``forward``, which forwards a given
-option unchanged, and ``append_cmd``, which appends a given string to the tool
-execution command. Multiple actions can be associated with a single condition by
-using a list of actions (used in the example to append some dummy options). The
-same ``case`` construct can also be used in the ``cmd_line`` property to modify
-the tool command line.
-
-The "join" property used in the example means that this tool behaves like a
-linker.
-
-The list of all possible actions follows.
-
-* Possible actions:
-
-   - ``append_cmd`` - Append a string to the tool invocation command.
-     Example: ``(case (switch_on "pthread"), (append_cmd "-lpthread"))``.
-
-   - ``error`` - Exit with error.
-     Example: ``(error "Mixing -c and -S is not allowed!")``.
-
-   - ``warning`` - Print a warning.
-     Example: ``(warning "Specifying both -O1 and -O2 is meaningless!")``.
-
-   - ``forward`` - Forward the option unchanged.
-     Example: ``(forward "Wall")``.
-
-   - ``forward_as`` - Change the option's name, but forward the argument
-     unchanged.
-     Example: ``(forward_as "O0", "--disable-optimization")``.
-
-   - ``forward_value`` - Forward only option's value. Cannot be used with switch
-     options (since they don't have values), but works fine with lists.
-     Example: ``(forward_value "Wa,")``.
-
-   - ``forward_transformed_value`` - As above, but applies a hook to the
-     option's value before forwarding (see `below`__). When
-     ``forward_transformed_value`` is applied to a list
-     option, the hook must have signature
-     ``std::string hooks::HookName (const std::vector<std::string>&)``.
-     Example: ``(forward_transformed_value "m", "ConvertToMAttr")``.
-
-     __ hooks_
-
-   - ``output_suffix`` - Modify the output suffix of this tool.
-     Example: ``(output_suffix "i")``.
-
-   - ``stop_compilation`` - Stop compilation after this tool processes its
-     input. Used without arguments.
-     Example: ``(stop_compilation)``.
-
-
-Language map
-============
-
-If you are adding support for a new language to LLVMC, you'll need to modify the
-language map, which defines mappings from file extensions to language names. It
-is used to choose the proper toolchain(s) for a given input file set. Language
-map definition looks like this::
-
-    def LanguageMap : LanguageMap<
-        [LangToSuffixes<"c++", ["cc", "cp", "cxx", "cpp", "CPP", "c++", "C"]>,
-         LangToSuffixes<"c", ["c"]>,
-         ...
-        ]>;
-
-For example, without those definitions the following command wouldn't work::
-
-    $ llvmc hello.cpp
-    llvmc: Unknown suffix: cpp
-
-The language map entries are needed only for the tools that are linked from the
-root node. A tool can have multiple output languages.
-
-Option preprocessor
-===================
-
-It is sometimes useful to run error-checking code before processing the
-compilation graph. For example, if optimization options "-O1" and "-O2" are
-implemented as switches, we might want to output a warning if the user invokes
-the driver with both of these options enabled.
-
-The ``OptionPreprocessor`` feature is reserved specially for these
-occasions. Example (adapted from ``llvm/src/Base.td.in``)::
-
-
-    def Preprocess : OptionPreprocessor<
-    (case (not (any_switch_on "O0", "O1", "O2", "O3")),
-               (set_option "O2"),
-          (and (switch_on "O3"), (any_switch_on "O0", "O1", "O2")),
-               (unset_option "O0", "O1", "O2"),
-          (and (switch_on "O2"), (any_switch_on "O0", "O1")),
-               (unset_option "O0", "O1"),
-          (and (switch_on "O1"), (switch_on "O0")),
-               (unset_option "O0"))
-    >;
-
-Here, ``OptionPreprocessor`` is used to unset all spurious ``-O`` options so
-that they are not forwarded to the compiler. If no optimization options are
-specified, ``-O2`` is enabled.
-
-``OptionPreprocessor`` is basically a single big ``case`` expression, which is
-evaluated only once right after the driver is started. The only allowed actions
-in ``OptionPreprocessor`` are ``error``, ``warning``, and two special actions:
-``unset_option`` and ``set_option``. As their names suggest, they can be used to
-set or unset a given option. To set an option with ``set_option``, use the
-two-argument form: ``(set_option "parameter", VALUE)``. Here, ``VALUE`` can be
-either a string, a string list, or a boolean constant.
-
-For convenience, ``set_option`` and ``unset_option`` also work with multiple
-arguments. That is, instead of ``[(unset_option "A"), (unset_option "B")]`` you
-can use ``(unset_option "A", "B")``. Obviously, ``(set_option "A", "B")`` is
-only valid if both ``A`` and ``B`` are switches.

-====================
-
-.. _hooks:
-
-Hooks and environment variables
--------------------------------
-
-Normally, LLVMC searches for programs in the system ``PATH``. Sometimes, this is
-not sufficient: for example, we may want to specify tool paths or names in the
-configuration file. This can be achieved via the hooks mechanism. To write your
-own hooks, add their definitions to the ``Hooks.cpp`` or drop a ``.cpp`` file
-into your driver directory. Hooks should live in the ``hooks`` namespace and
-have the signature ``std::string hooks::MyHookName ([const char* Arg0 [ const
-char* Arg2 [, ...]]])``. They can be used from the ``command`` tool property::
-
-    (command "$CALL(MyHook)/path/to/file -o $CALL(AnotherHook)")
-
-To pass arguments to hooks, use the following syntax::
-
-    (command "$CALL(MyHook, 'Arg1', 'Arg2', 'Arg # 3')/path/to/file -o1 -o2")
-
-It is also possible to use environment variables in the same manner::
-
-   (command "$ENV(VAR1)/path/to/file -o $ENV(VAR2)")
-
-To change the command line string based on user-provided options use
-the ``case`` expression (documented `above`__)::
-
-    (command
-      (case
-        (switch_on "E"),
-           "llvm-g++ -E -x c $INFILE -o $OUTFILE",
-        (default),
-           "llvm-g++ -c -x c $INFILE -o $OUTFILE -emit-llvm"))

-When writing LLVMC-based drivers, it can be useful to get a visual view of the
-resulting compilation graph. This can be achieved via the command line option
-``--view-graph`` (which assumes that Graphviz_ and Ghostview_ are
-installed). There is also a ``--write-graph`` option that creates a Graphviz
-source file (``compilation-graph.dot``) in the current directory.
-
-Another useful ``llvmc`` option is ``--check-graph``. It checks the compilation
-graph for common errors like mismatched output/input language names, multiple
-default edges and cycles. When invoked with ``--check-graph``, ``llvmc`` doesn't
-perform any compilation tasks and returns the number of encountered errors as
-its status code. In the future, these checks will be performed at compile-time
-and this option will disappear.

-
-Conditioning on the executable name
------------------------------------
-
-For now, the executable name (the value passed to the driver in ``argv[0]``) is
-accessible only in the C++ code (i.e. hooks). Use the following code::
-
-    namespace llvmc {
-    extern const char* ProgramName;
-    }
-
-    namespace hooks {
-
-    std::string MyHook() {
-    //...
-    if (strcmp(ProgramName, "mydriver") == 0) {
-       //...
-
-    }
-
-    } // end namespace hooks
-
-In general, you're encouraged not to make the behaviour dependent on the
-executable file name, and use command-line switches instead. See for example how
-the ``llvmc`` program behaves when it needs to choose the correct linker options
-(think ``g++`` vs. ``gcc``).

-Introduction
-============
-
-LLVMC is a generic compiler driver, which plays the same role for LLVM as the
-``gcc`` program does for GCC - the difference being that LLVMC is designed to be
-more adaptable and easier to customize. Most of LLVMC functionality is
-implemented via high-level TableGen code, from which a corresponding C++ source
-file is automatically generated. This tutorial describes the basic usage and
-configuration of LLVMC.
-
-
-Using the ``llvmc`` program
-===========================
-
-In general, ``llvmc`` tries to be command-line compatible with ``gcc`` as much
-as possible, so most of the familiar options work::
-
-     $ llvmc -O3 -Wall hello.cpp
-     $ ./a.out
-     hello
-
-This will invoke ``llvm-g++`` under the hood (you can see which commands are
-executed by using the ``-v`` option). For further help on command-line LLVMC
-usage, refer to the ``llvmc --help`` output.
-
-
-Using LLVMC to generate toolchain drivers
-=========================================
-
-LLVMC-based drivers are written mostly using TableGen_, so you need to be
-familiar with it to get anything done.
-
-.. _TableGen: http://llvm.org/docs/TableGenFundamentals.html
-
-Start by compiling ``example/Simple``, which is a primitive wrapper for
-``gcc``::
-
-    $ cd $LLVM_OBJ_DIR/tools/examples/Simple
-    $ make
-    $ cat > hello.c
-    #include <stdio.h>
-    int main() { printf("Hello\n"); }
-    $ $LLVM_BIN_DIR/Simple -v hello.c
-    gcc hello.c -o hello.out
-    $ ./hello.out
-    Hello
-
-We have thus produced a simple driver called, appropriately, ``Simple``, from
-the input TableGen file ``Simple.td``. The ``llvmc`` program itself is generated
-using a similar process (see ``llvmc/src``). Contents of the file ``Simple.td``
-look like this::
-
-    // Include common definitions
-    include "llvm/CompilerDriver/Common.td"
-
-    // Tool descriptions
-    def gcc : Tool<
-    [(in_language "c"),
-     (out_language "executable"),
-     (output_suffix "out"),
-     (command "gcc"),
-     (sink),
-
-     // -o is what is used by default, out_file_option here is included for
-     // instructive purposes.
-     (out_file_option "-o")
-    ]>;
-
-    // Language map
-    def LanguageMap : LanguageMap<[(lang_to_suffixes "c", "c")]>;
-
-    // Compilation graph
-    def CompilationGraph : CompilationGraph<[(edge "root", "gcc")]>;
-
-As you can see, this file consists of three parts: tool descriptions, language
-map, and the compilation graph definition.
-
-At the heart of LLVMC is the idea of a compilation graph: vertices in this graph
-are tools, and edges represent a transformation path between two tools (for
-example, assembly source produced by the compiler can be transformed into
-executable code by an assembler). The compilation graph is basically a list of
-edges; a special node named ``root`` is used to mark graph entry points.
-
-Tool descriptions are represented as property lists: most properties in the
-example above should be self-explanatory; the ``sink`` property means that all
-options lacking an explicit description should be forwarded to this tool.
-
-The ``LanguageMap`` associates a language name with a list of suffixes and is
-used for deciding which toolchain corresponds to a given input file.
-
-To learn more about writing your own drivers with LLVMC, refer to the reference
-manual and examples in the ``examples`` directory. Of a particular interest is
-the ``Skeleton`` example, which can serve as a template for your LLVMC-based
-drivers.

-This is a basic compiler driver for the PIC16 toolchain that shows how to create
-your own llvmc-based drivers. It is based on the examples/Skeleton template.
-
-The PIC16 toolchain looks like this:
-
-clang-cc (FE) -> llvm-ld (optimizer) -> llc (codegen) -> native-as -> native-ld
-
-Following features were requested by Sanjiv:
-
-From: Sanjiv Gupta <sanjiv.gupta <at> microchip.com>
-Subject: Re: llvmc for PIC16
-Newsgroups: gmane.comp.compilers.llvm.devel
-Date: 2009-06-05 06:51:14 GMT
-
-The salient features that we want to have in the driver are:
-1. llvm-ld will be used as "The Optimizer".
-2. If the user has specified to generate the final executable, then
-llvm-ld should run on all the .bc files generated by clang and create a
-single optimized .bc file for further tools.
-3. -Wo <options> - pass optimizations to the llvm-ld
-4. mcc16 -Wl <options> - pass options to native linker.
-5. mcc16 -Wa <options> - pass options to native assembler.
-
-Here are some example command lines and sample command invocations as to
-what should be done.
-
-$ mcc16 -S foo.c
-// [clang-cc foo.c] -> foo.bc
-// [llvm-ld foo.bc] -> foo.opt.bc
-// [llc foo.opt.bc] -> foo.s
-
-$ mcc16 -S foo.c bar.c
-// [clang-cc foo.c] -> foo.bc
-// [llvm-ld foo.bc] -> foo.opt.bc
-// [llc foo.opt.bc] -> foo.s
-// [clang-cc bar.c] -> bar.bc
-// [llvm-ld bar.bc] -> bar.opt.bc
-// [llc bar.opt.bc] -> bar.s
-
-** Use of -g causes llvm-ld to run with -disable-opt
-$ mcc16 -S -g foo.c
-// [clang-cc foo.c] -> foo.bc
-// [llvm-ld -disable-opt foo.bc] -> foo.opt.bc
-// [llc foo.opt.bc] -> foo.s
-
-** -I is passed to clang-cc, -pre-RA-sched=list-burr to llc.
-$ mcc16 -S -g -I ../include -pre-RA-sched=list-burr foo.c
-// [clang-cc -I ../include foo.c] -> foo.bc
-// [llvm-ld -disable-opt foo.bc] -> foo.opt.bc
-// [llc -pre-RA-sched=list-burr foo.opt.bc] -> foo.s
-
-** -Wo passes options to llvm-ld
-$ mcc16 -Wo=opt1,opt2 -S -I ../include -pre-RA-sched=list-burr foo.c
-// [clang-cc -I ../include foo.c] -> foo.bc
-// [llvm-ld -opt1 -opt2 foo.bc] -> foo.opt.bc
-// [llc -pre-RA-sched=list-burr foo.opt.bc] -> foo.s
-
-** -Wa passes options to native as.
-$ mcc16 -c foo.c -Wa=opt1
-// [clang-cc foo.c] -> foo.bc
-// [llvm-ld foo.bc] -> foo.opt.bc
-// [llc foo.opt.bc] -> foo.s
-// [native-as -opt1 foo.s] -> foo.o
-
-$ mcc16 -Wo=opt1 -Wl=opt2 -Wa=opt3 foo.c bar.c
-// [clang-cc foo.c] -> foo.bc
-// [clang-cc bar.c] -> bar.bc
-// [llvm-ld -opt1 foo.bc bar.bc] -> a.out.bc
-// [llc a.out.bc] -> a.out.s
-// [native-as -opt3 a.out.s] -> a.out.o
-// [native-ld -opt2 a.out.o] -> a.out
-
-Is this achievable by a tablegen based driver ?
