Remove llvmc and assorted build machinery for it.
The problems that llvmc solved have largely been subsumed with the tasks that the clang driver can accomplish, but llvmc lacks flexibility and depends too heavily on the EOL'd llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140093 91177308-0d34-0410-b5e6-96231b3b80d8

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 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"))
|
||||
|
||||
__ case_
|
||||
|
||||
Debugging
|
||||
---------
|
||||
|
||||
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.
|
||||
|
||||

|
||||
.. _Ghostview: http://pages.cs.wisc.edu/~ghost/
|
||||
|
||||
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 ?
