* Allow optimizer to depend on preloaded symbols
It is safe for the optimizer to rely on preloaded symbols. This can occur when
compiling non-preloaded files, referencing preloaded ones.
* Disable inline pass for observer test
* Move duplicated code into functions
* Add comment to specific optimization value
* Optimizer should only rely on preloaded symbols in the symbol table
* Fix skipif for windows
Instead of fixing up temporaries count in between observer steps, just apply the additional temporary in the two affected observer steps.
Closes GH-14018.
The problem is that this line in the VM: `ZVAL_NULL(result);` changes the type
of arg1 as well, because after the DFA pass the result and input both use
CV0($result).
We should not contract assignments with CVs in frameless calls with
arguments.
An older attempt is found at GH-14876 that tried to modify the VM/JIT.
Closes GH-14903.
* Include the source location in Closure names
This change makes stack traces involving Closures, especially multiple
different Closures, much more useful, because it's more easily visible *which*
closure was called for a given stack frame.
The implementation is similar to that of anonymous classes which already
include the file name and line number within their generated classname.
* Update scripts/dev/bless_tests.php for closure naming
* Adjust existing tests for closure naming
* Adjust tests for closure naming that were not caught locally
* Drop the namespace from closure names
This is redundant with the included filename.
* Include filename and line number as separate keys in Closure debug info
* Fix test
* Fix test
* Include the surrounding class and function name in closure names
* Fix test
* Relax test expecations
* Fix tests after merge

This regressed in 9a250cc9d6, which allowed static properties to get
overridden by a trait during inheritance. In particular, because of the
change to the loop in zend_update_parent_ce(), it's not guaranteed that
all indirects are after one another.
This means that during persisting the zvals of the static members table,
some static properties may be skipped. In case of the test code, this
means that the array in the trait will keep referring to the old, new
freed, stale value. To solve this, we check the type for IS_INDIRECT,
which is the same as what zend_persist_calc() is already doing anyway.
Since 2543e61aed we can check for IS_INDIRECT to see if it should be
persisted or not.
Closes GH-13794.
Compress interned string table offsets and increase maximum supported buffer size
The interned string buffer is organized as a header + a hash table + a
zend_string arena. Hash slots point to the arena, but are represented as 32bit
offsets from the buffer, which limits the maximum buffer size to about 4GiB.
However zend_strings are 8-byte aligned in the buffer, so we can compress the
3 lower bits. This allows to increase the maximum supported interned string
buffer size from 4095 MiB to 32767 MiB.
Inherited methods regardless of source must share the original runtime cache. Traits were missed.
This adds ZEND_ACC_TRAIT_CLONE to internal functions as well to allow easy distinction of these.
