7f67513ca3 Lazy function copying from op_cache SHM into process memory 2018-06-25 19:53:58 +03:00

d04917c7b3 Fixed bug #75218 
I've introduced a new CompileError type, from which ParseError
inherits. These errors are not parse errors in the narrow sense
of the term, even though they happen to be generated during
parsing in our implementation. Additionally reusing the ParseError
class for this purpose would change existing error messages (if
the exception is not caught) from a "Fatal error:" to a "Parse
error:" prefix, and also the error kind from E_COMPILE_ERROR to
E_PARSE.

7ff186434e Explicitly sort live ranges by start opnum 
Instead of moving live ranges around to maintain the start opnum
invariant, add an explicit sorting step in pass two.

b0af9ac733 Avoid live range references in opcodes 
Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.

7141631cc8 Change FETCH/ISSET instruction modifiers: 
- Get rid of ZEND_ISEMPTY and ZEND_ISSET_ISEMPTY_MASK. Use just single ZEND_ISSET bit to make distinct between isset() and empty()
- Use ZEND_FETCH_GLOBAL, ZEND_FETCH_LOCAL and ZEND_FETCH_GLOBAL_LOCK as bitmask
- Removed unused ZEND_FETCH_STANDARD
- Extended ZEND_FETCH_ARG_MASK

a484b9a535 Fix #75765 Exception on extend of undefined class 
As the parent class is fetched prior to binding, there are no
safety concerns in this case and we can replace the fatal error
with an Error exception.

is also important for properties and internal classes.

33b094479b TYPE_CHECK instruction changed. Now it keeps in extended_value a type mask. 
This makes check for "boolean" cheaper and allows check combination e.g. (is_string($a) || is_null($a))

9fbb019848 Move adjust_for_fetch_type directly after emission 
And drop the distinction between compile_X and compile_X_common.

ignoring the BP_VAR type passed to it...
