Abt RTL expression

[Mohamed Shafi]

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,
