Dmitry Stogov 19854371ed Tracing JIT: Fixed bug in register allocator. 
Type of variable might need to be checked (using type guard) before loading to register.

Nikita Popov a846547ed4 Fix range() return type inference for undef operand 
This results in a long range.

  Don't unconditionally add array value type for undef
 2021-09-21 14:54:34 +02:00
Nikita Popov 61445248cb Don't unconditionally add array value type for undef 
We have an invariant that an array value type is set if and only
if an array key type is set, which is violated for the case of
undef values for always invalid keys.

  Check for undef var in typed property assignment
 2021-09-21 14:11:56 +02:00
Nikita Popov f4bcf8c393 Check for undef var in typed property assignment 
Without this check the assignment would actually silently succeed,
not just skip the warning.

Dmitry Stogov 48d050ef72 JIT: Disable recursive call optimization for VM without global register variables 
A tail-call to VM handler from recursively called function may lead to
pass control to incorrect stack frame.

  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).

 2021-09-17 17:05:42 +02:00
Nikita Popov a49a309386 Fix FETCH_OBJ_IS type inference 
Even if the property is typed, null is still a valid return
value in the BP_VAR_IS case. Other cases will throw instead.

Nikita Popov e0e5b59d2e Try harder to clean up unreachable loop free block 
While we can't drop the loop free, we can drop other instructions
in the same block. We should also indicate that it no longer has
predecessors.

  Don't jit FE_RESET_R with undef operand
 2021-09-17 12:04:43 +02:00
Nikita Popov d46b10296e Don't jit FE_RESET_R with undef operand 
The implementation currently assumes that the operand is always
an array, but this did not account for a possibly undef operand.
