* PHP-8.1:
  Fix GH-8140: Wrong first class callable by name optimization
 2022-02-24 10:37:34 +01:00
Christoph M. Becker 33cd61c904 Fix GH-8140: Wrong first class callable by name optimization 
When optimizing by name function calls, we must not replace
`CALLABLE_CONVERT` opcodes, but have to keep them.

Closes GH-8144.

Christoph M. Becker ef80dcb80b Fix GH-8074: Wrong type inference of range() result 
If either the first or second operand of `range()` may be a string, we
must not exclude the possibility that the result may be an array of
longs.

Closes GH-8131.

Nikita Popov 902d64390e Deprecate implicit dynamic properties 
Writing to a proprety that hasn't been declared is deprecated,
unless the class uses the #[AllowDynamicProperties] attribute or
defines __get()/__set().

DCE might remove INIT_ARRAY instruction but then keep the related
ADD_ARRAY_ELEMENT, becuse its both operands need to be freed.

  Don't replace values in unreachable code in sccp
 2021-09-20 13:12:43 +02:00
Nikita Popov 1b33da5dd2 Don't replace values in unreachable code in sccp 
While technically legal, this may cause unexpected situations
(in this example, setting an FE_FREE operand to constant null)
and is suboptimal anyway. It's better to preserve the vacuous type
and drop it later (though we currently don't implement this).

Nikita Popov a30fab57eb Make can_elide_return_type_check() more robust 
Rather than using def_info, check against the actual arg_info type.
As it is stored as a type mask nowadays, this is not much harder,
but more general and more robust as we don't need to deal with
inaccurate cases.
