5662d73528 Add support for Pi type constraints
Supports TYPE_CHECK and IS_IDENTICAL for now.

a2ff3a46a4 Use ZEND_FUNC_INDIRECT_VAR_ASSESS instead of ZEND_FUNC_TOO_DYNAMIC. Handle function with exceptions handlers and generators separately. 2016-01-19 15:33:08 +03:00

6579e48417 Introduced BIND_STATIC opcode instead of FETCH_R/FETCH_W(static)+ASSIGN/ASSIGN_REF (similar to BIND_GLOBAL).
In the future we may refer to static variable by index instead of name, to eliminate hash lookup.

65e456f364 Introduce BIND_LEXICAL
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.

This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

33870c525a Don't reuse SSA var in UNSET_VAR
Instead use the SSA var that UNSET_VAR actually defines. Otherwise
we get issues trying to DCE unsets.
