Support VERIFY_RETURN_TYPE elision with unused operand

2021-03-22T13:54:29+00:00

This handles the degenerate case where SCCP replaced the value in
the RETURN opcode with a constant, but the VERIFY_RETURN is still
there. We can still apply the same optimization, just don't need
to adjust the use list in this case.

The result is still sub-optimal in that a dead QM_ASSIGN is left
behind.

Use zend_string* instead of char*

2021-03-22T11:56:16+00:00

Use zend_hash_lookup()

2021-03-19T20:34:38+00:00

Support prototypes in call graph

2021-03-19T09:49:15+00:00

Even if we don't know the exact method being called, include it
in the call graph with the is_prototype flag. In particular, we
can still make use of return types from prototype methods, as
PHP 8 makes LSP violations a hard error.

Most other places are adjusted to skip calls with !is_prototype.
Maybe some of them would be fine, but ignoring them is conservative.
