6a911e833f Optimized JMPZNZ to avoid multiplication at runtime (may be it makes sense to use relative addresses everywere it'll lead to Position Independent Code) 2014-04-30 11:23:19 +04:00

f9927a6c97 Merge mainstream 'master' branch into refactoring 
During merge I had to revert:
	Nikita's patch for php_splice() (it probably needs to be applyed again)
	Bob Weinand's patches related to constant expression handling (we need to review them carefully)
	I also reverted all our attempts to support sapi/phpdbg (we didn't test it anyway)

e96073b1e4 Moved zend_literal->cache_slot right into zval. 
It should be accessed using Z_CACHE_SLOT() macro.
zend_literal structure is removed.
API functions that accepted pointer to zend_literal now accept pointer to zval or cache_slot directly.
Calls of such functiond that now accept cache_slot need to be changed to pass -1 instead of NULL.

e0dd8a4f4b Fixed IS_INDIRECT handling when assign array element by reference. 
This might cause passing invalid pointer if the array could be resized before IS_INDIRECT usage.
Now we use IS_REFERENCE instead of IS_INDIRECT.
The following test crashed before:
<?php $a = array(0,1,2,3,4,5,6,7); $a[8] = &$a[7]; ?>
