George Peter Banyard 3e6667d338 Fix -Wtype-limits warning by using correct type declaration in JIT trace 
Namely int as that is the type of 'definition'

Closes GH-5299

Dmitry Stogov ce8202f996 Rename "var" to "stack". This is an abstract stack that holds TSSA variable numbers. 2020-03-25 10:49:01 +03:00
Dmitry Stogov af3142daaf Make SSA dump format controlled by opcache.jit_debug more readable (always print opcode number). 
This doesn't affect dumps controlled by opcache.opt_debug_level.

Tyson Andre 26b9780d02 Fix compilation error on mac with -Wshift-negative-value 
Fix for mac OS build error seen in ccc49ead68
when shifting -1 (max argument count?)

```

error: shifting a negative signed value is undefined
[-Werror,-Wshift-negative-value]
        TRACE_FRAME_INIT(frame, op_array, 0, -1);
```

Dmitry Stogov 4bf2d09ede Tracing JIT (it doesn't support register allocation yet) 
Use opcache.jit=1255 to swith it on (the third digit 5 really matters)
Use opcache.jit_debug=0xff001 to see how it works and what code it generates
 2020-03-13 22:11:07 +03:00

Nikita Popov 43443857b7 Add static return type 
RFC: https://wiki.php.net/rfc/static_return_type

The "static" type is represented as MAY_BE_STATIC, rather than
a class type like "self" and "parent", as it has special
resolution semantics, and cannot be cached in the runtime cache.

Closes GH-5062.
 2020-02-17 11:51:09 +01:00
Nikita Popov f3d8ac1d95 Fix JIT trait type errors 
We need to load EX->func here rather than use a hardcoded op_array,
as it may be copied with adjusted scope for traits.
