The following opcodes would be generated: ... BB1: 0003 JMP BB3 BB2: 0004 INIT_FCALL 1 96 string("chr") 0005 #10.T3 [long] = SR #3.CV0($int) [long] #7.CV2($i) ... 0006 #11.T4 [long] RANGE[0..127] = BW_AND #10.T3 [long] ... 0007 #12.T3 [long] RANGE[128..255] = BW_OR #11.T4 [long] ... 0008 SEND_VAL #12.T3 [long] RANGE[128..255] 1 0009 #13.V3 [ref, rc1, rcn, any] = DO_ICALL 0010 ASSIGN_OP (CONCAT) #6.CV1($out) [rc1, rcn, string] 0011 ADD #7.CV2($i)... int(7) #7.CV2($i) ... -> #15.CV2($i) ... BB3: 0012 #8.T4 [long] = SR #3.CV0($int) #7.CV2($i) [long, double] 0013 #9.T3 [bool] RANGE[0..1] = IS_SMALLER int(128) #8.T4 0014 JMPNZ #9.T3 [bool] RANGE[0..1] BB2 ... Main changes are: 1. SR opcode covers new path in function zend_jit_long_math_helper(). 2. BW_AND and BW_OR opcodes are supported. See macro LONG_OP. 3. Function zend_jit_concat_helper() is added to support ASSIGN_OP opcode. Speficically, CONCAT and FAST_CONCAT is supported for statements "$out .= ...". 4. New path is covered in function zend_jit_cmp_long_long() by IS_SMALLER opcode. 5. New path is covered in macros ZVAL_PTR_DTOR and ZVAL_DTOR_FUNC when leaving.
