instruction codes - novice questions

["Dragos Badea" <badrian at ss dot pub dot ro>]

 

Hi!

 

1. Here it is part of after-flow-pass dump.

 

(insn 9 6 11 (set (reg:SI 22)

(mem/f:SI (plus:SI (reg:SI 6 %ebp)

(const_int -8 [0xfffffff8])) 0)) 48 {movsi+2} (nil)

(nil))

 

Could you tell me please, when were

48 {movsi+2}

fields added and which is their meaning (what is +2 ?).

 

2.Are the instructions scheduled by sched.c in a 1-1 relation to asm output instructions (without taking into account the afterwards effect of peephole optimizations) ?

 

 

 Thank you very much.
