Subject: Abt RTL expression

Hello all,

Can anyone tell me what the below expression means ?


(insn 38 37 40 4 (parallel [
          (asm_operands/v ("") ("") 0 [                          //line 2
                  (reg:SI 32 [ s5.1 ])
    //line 3
              ]
               [
                  (asm_input:SI ("r"))
   //line 6
              ] ("test55.c") 42)
        //line 7
          (clobber (mem:BLK (scratch) [0 A8]))
//line 8
      ]) -1 (nil)
  (nil))

in line 2, what is the 0 for?

what does line 3 mean?what is it purpose ?

In line 7 test55.c is the file name . why is it needed and what is 42?
In line 8 what does [0 A8] mean?

Thanks in advance,

shafi
