Additional code
---------------

portAB = \B;
endcode
There is an implicit `code..endcode` block at the end of each `.pmg` file
that just accepts everything that gets all the way there.
There is an implicit `code..endcode` block at the end of each (sub)pattern
that just rejects.
A `code..finally..endcode` block executes the code after `finally` during
back-tracking. This is useful for maintaining user data state or printing
debug messages. For example:
udata <vector<Cell*>> stack
code
stack.push_back(addAB);
...
finally
stack.pop_back();
endcode
`accept` and `finish` statements can be used inside the `finally` section,
but not `reject`, `branch`, or `subpattern`.
Declaring a subpattern
----------------------
A subpattern starts with a line containing the `subpattern` keyword followed
by the name of the subpattern. Subpatterns can be called from a `code` block
using a `subpattern(<subpattern_name>);` C statement.
Arguments may be passed to subpattern via state variables. The `subpattern`
line must be followed by a `arg <arg1> <arg2> ...` line that lists the
state variables used to pass arguments.
state <IdString> foobar_type
state <bool> foobar_state
code foobar_type foobar_state
foobar_state = false;
foobar_type = $add;
subpattern(foo);
foobar_type = $sub;
subpattern(bar);
endcode
subpattern foo
arg foobar_type foobar_state
match addsub
index <IdString> addsub->type === foobar_type
...
endmatch
code
if (foobar_state) {
subpattern(tail);
} else {
foobar_state = true;
subpattern(bar);
}
endcode
subpattern bar
arg foobar_type foobar_state
match addsub
index <IdString> addsub->type === foobar_type
...
endmatch
code
if (foobar_state) {
subpattern(tail);
} else {
foobar_state = true;
subpattern(foo);
}
endcode
subpattern tail
...
Subpatterns cann be called recursively.
If a `subpattern` statement is preceded by a `fallthrough` statement, this is
equivalent to calling the subpattern at the end of the preceding block.
Generate Blocks
---------------
Match blocks may contain an optional `generate` section that is used for automatic
test-case generation. For example:
match mul
...
generate 10
SigSpec Y = port(ff, \D);
SigSpec A = module->addWire(NEW_ID, GetSize(Y) - rng(GetSize(Y)/2));
SigSpec B = module->addWire(NEW_ID, GetSize(Y) - rng(GetSize(Y)/2));
module->addMul(NEW_ID, A, B, Y, rng(2));
endmatch
The expression `rng(n)` returns a non-negative integer less than `n`.
The argument to `generate` is the chance of this generate block being executed
when the match block did not match anything, in percent.
The special statement `finish` can be used within generate blocks to terminate
the current pattern matcher run.
