unless the class uses the #[AllowDynamicProperties] attribute or
defines __get()/__set().

Nikita Popov b9165671d5 Verify that used SSA variables are defined 
There should either be a defining instruction, defining phi, or
it should be an undef entry variable.

Dmitry Stogov 90b7bde615 Use more compact representation for packed arrays. 
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
  instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
  familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
  (ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
  (packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
  ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values

Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)

TODO:
    - sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
    - zend_hash_sort_ex() may require converting packed arrays to hash.

Nikita Popov 64878757be Fix scdf loop var free check for phi vars 
The variable may come from a phi node, in which case we should
take the defining block from it.

  Handle operand replacement in JMP_NULL
 2021-10-19 15:19:39 +02:00
Nikita Popov 1f19401ffa Handle operand replacement in JMP_NULL 
In this case it's not sufficient to replace the JMP_NULL operand,
as it keeps the temporary alive and there may be more uses later.
Fix this by generalizing existing handling for other similar opcodes
like CASE/SWITCH and LIST_R.

Fixes oss-fuzz 5820123475214336.
