- dba008.phpt never runs anyway, no need to keep it
- bug75357.phpt has a branch that is never hit, which should not change the bug behavior in anyway
- bug55371.phpt added a simple 'done' test to not let the EXPECT section be empty
* Adjust IS_SERIALIZED() check to account for potential empty
allocations at the end of the memory region.
* Deallocate empty allocation if all try/catch elements have been
removed in the block pass (similar to what we do if all live
ranges have been eliminated).
Without the type hint the previous optimization no longer applied,
as the result could be an (overloaded) object, which might have
caused dtor effect reordering.
The negative range inference implementation does not work correctly,
and it's not clear right now how it can be fixed. As such, disable
it entirely for now.
Move NOP stripping out of zend_optimize_block: NOP stripping may
move instructions, which may invalidate a Tsource shared across
an extended basic block.
It is not sufficient to just add the additional types for aliased
variables at the end of type inference, because types of derived
variables may depend on them. Make sure the additional types are
always added whenever the type of an aliased variable is updated.
Don't try to evaluate substr() and strpos() at compile-time if
mbstring function overloading is enabled. I'm reusing the
COMPILE_NO_BUILTIN_STRLEN for the detection of mbstring function
overloading here, even if it's technically only about strlen()...
PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
