stores new offsets in op_array->opcodes[*].op?.num. You can use macros
EX_TMP_VAR() and EX_TMP_VAR_NUM() to access temp_variable by offset or
number. You can convert number to offset using EX_TMP_VAR_NUM(0, num) or
- offset to number (EX_TMP_VAR(0,offset)-EX_TMP_VAR_NUM(0,0)).
+ offset to number (EX_TMP_VAR_NUM(0,0)-EX_TMP_VAR(0,offset)).
- Removed execute_data->CVs field. The VM compiled variables always allocated
immediately after execute_data structure. Now they are accessed by offset
from the execute_data base pointer (instead of execute_data->CVs). You can
#define DECODE_CTOR(ce) \
((zend_class_entry*)(((zend_uintptr_t)(ce)) & ~(CTOR_CALL_BIT|CTOR_USED_BIT)))
