Creating native instructions in PHP since 2014

jitfu's Issues

Add mock classes/interfaces for type introspection

Simple enough, take this bit of code, pasted here as reference:

zend_function_entry php_jit_type_methods[] = {
    PHP_ME(Type, __construct,     php_jit_type_construct_arginfo, ZEND_ACC_PUBLIC)
    PHP_ME(Type, getIdentifier,   php_jit_no_arginfo,             ZEND_ACC_PUBLIC)
    PHP_ME(Type, getIndirection,  php_jit_no_arginfo,             ZEND_ACC_PUBLIC)
    PHP_ME(Type, isPointer,       php_jit_no_arginfo,             ZEND_ACC_PUBLIC)
    PHP_ME(Type, dump,            php_jit_type_dump_arginfo,      ZEND_ACC_PUBLIC)
    PHP_ME(Type, of,              php_jit_type_of_arginfo,        ZEND_ACC_PUBLIC|ZEND_ACC_STATIC)
    PHP_FE_END
};

and create a stub class of it to allow doc generation:

throw new \Exception('Do not manually include');

/**
 * Stub class - do not manually include
 */
class Type
{
    public function __construct() {}
    public function getIdentifier() {}
    public function getIndirection() {}
    public function isPointer() {}
    public function dump() {}
    public function of() {}
}

If all I have to look for is PHP_ME then I can do it myself and PR.

It can also be on a separate package that just requires the extension (if this metadata is not wanted here).

Add installation steps

It's currently a bit messy to get libjit and jitfu both running together: may add a git submodule?

configure: error: wrong libjit version or libjit not found

I have built libjit from current Git master (./configure --prefix=/usr/local/libjit, make, make install).

When I try to configure the jitfu build (phpize, ./configure --with-jitfu=/usr/local/libjit), I get the following

$ ./configure --with-jitfu=/usr/local/libjit

Which version of libjit supported?

I tried http://ftp.gnu.org/old-gnu/dotgnu/libjit/libjit-0.1.2.tar.gz with no luck.

Installation problems - yacc and syntax error

During installation, I was first told yacc command not found. This was fixed by installing byacc. Then, I got this after re-running make:

Support for objects / strucutures

Is there a way to support "native" objects or structures ?
I see there is a Struct object defined but there are no examples.

Thanks
