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.
