Supported types

[rybakit]

I tried to modify 01-simple-usage.php to use string instead of int like this:

/**
 * @param string $n The parameter
 *
 * @return string The parameter, returned
 */
function test($n)
{
    return $n;
}

$func = Jit::jitfu('test');
benchmark($func, "ReckiCT");

function benchmark(callable $func, $label)
{
    $start = microtime(true);
    for ($i = 0; $i < 1000000; $i++) {
        $func('x');
    }
    $end = microtime(true);
    printf("%s completed in %01.4F seconds\n", $label, $end - $start);
}

And got a fatal error:

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 947180166 bytes) in ...

Then I tried array type:

/**
 * @param array $n The parameter
 *
 * @return array $n
 */
function test($n)
{
    return [$n];
}

...

function benchmark(callable $func, $label)
{
    ...
    $func([]);
    ....
}

And got:

Fatal error: Uncaught exception 'LogicException' with message 'Found node without parser rule: Expr_Array' ...

So I wonder which types are supported?

Arrays and strings are only sort-of supported. The exact level of support is extremely limited and shouldn't be relied upon (will change over time).
