* Implement single-pass live range calculationNikita Popov2019-01-211-8/+0
| | | | | | | | Instead of interleaving creation of live-ranges with the main compiler code, compute them in a separate pass over the opcodes as part of pass_two. Additionally, do not keep live ranges synchronized during optimization in opcache and instead use the same mechanism to recompute them after optimization.

* | Remove EXT_TYPE_UNUSED in favor of IS_UNUSEDNikita Popov2016-02-111-9/+4
| | | | | | | | | | | | | | | | | | | | | | This means we no longer allocate an unused VAR for the retval of instructions that support unused results. Nearly all instructions already used the result variable only if it was used. The only exception to this was the return value variable for internal function call results. I've adjusted the code to use a stack zval for the unused return case now. As we have retval specialization now, we know that it doesn't matter.

* | Remove uses of VARs in extended_valueNikita Popov2015-12-211-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were referencing the parent ce VAR through extended_value. This is hacky and we can't track the def-use chain in SSA. To avoid this, the layout of declaration opcodes is changed as follows: op1 points to the lcname and rtd_key literals, in that order. (For anon/lambda declarations only one of lcname or rtd_key is present.) This frees up op2, which is now used to reference the parent ce VAR in inheriting declarations. The jmp offset for anon class declarations is moved frop op2 to extended_value. The changes were applied both to class and function declarations to keep everything symmetric.

It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy. - it makes no difference if array given to "foreach by value" is reference itself - "foreach by reference" still use internal array/object pointer and should work similar to PHP-5.
