- all rules from pass2 moved to pass1
- all JMP unrelated rules from pass3 moved to pass1
- pass3 keeps only JMP optimization rules
- pass2.c is removed
- pass1_5.c remaned to pass1.c ("_5" was related to PHP 5)
This reverts commit b09bddcaa5.
This causes test failures on macos -- presumably the relevant
difference is that it has no global regs. I suspect that this
is related to the fact that SAVE_VALID_OPLINE may use r0 as
a scratch register, which is already in use. Reverting for now.
The verify arg functions may throw an exception, so we need to save
the opline beforehand. Asan failures could be observed in
Zend/tests/type_declarations/scalar_constant_defaults.phpt
with a ZTS build.
It is now only used to signal exceptions for property reads. ERROR
zvals are never returned back to the VM anymore, so there's no
need to check for them when receiving a VAR.
Also return MAY_BE_ERROR, as ERROR is now no longer relevant for
inference.
Resources used as array keys are generally handled by throwing a
notice and converting the resource to the resource handle. The only
exception is the [$resource => null] syntax, where this was treated
as an illegal offset type instead. However, this also only happened
for VM evaluations, the AST evaluator did handle resources correctly.
This removes object auto-vivification support.
This also means that we can remove the corresponding special
handling for typed properites: We no longer need to check that a
property is convertible to stdClass if such a conversion might
take place indirectly due to a nested property write.
Additionally OBJ_W style operations now no longer modify the
object operand, and as such we no longer need to treat op1 as a
def in SSA form.
The next step would be to actually compile the whole LHS of OBJ_W
operations in R rather than W mode, but that causes issues with
SimpleXML, whose object handlers depend on the current compilation
structure.

This switches zend_type from storing a single IS_* type code to
storing a MAY_BE_* type mask. Right now most code still assumes
that there is only a single type in the mask (or two together
with MAY_BE_NULL). But this will make it a lot simpler to introduce
union types.
An additional advantage (and why I'm doing this separately), is
that a number of special cases no longer need to be handled
separately: We can do a single mask & (1 << type) check to handle
all simple types, booleans (true|false) and null.
This patch saves one CPU instruction on each "_tsrm_ls_cache" access in ZTS CLI/CGI/FPM builds.
This reduce typical instruction sequence for EG(current_execute_data) access from 4 to 3 CPU instructions.
This is a fix for symfony/symfony#32995.
The behavior is:
* Throwing exception when loading parent/interface is allowed
(and we will also throw one if the class is simply not found).
* If this happens, the bucket key for the class is reset, so
it's possibly to try registering the same class again.
* However, if the class has already been used due to a variance
obligation, the exception is upgraded to a fatal error, as we
cannot safely unregister the class stub anymore.
