So my guess is that the syntax is VCG's.
Forgive me, I had mistake in the question - I meant the debug dump files
that we get just by using the -fdump-rtl-all. not the vcg files.
how can I understand their syntax ?
thanks..

some example:
;; Function fun1 (fun1)
(note 2 0 3 NOTE_INSN_DELETED)
(note 3 2 6 NOTE_INSN_FUNCTION_BEG)
(note 6 3 20 [bb 1] NOTE_INSN_BASIC_BLOCK)
(insn/f 20 6 21 (set (mem:SI (pre_dec:SI (reg/f:SI 7 sp)) [0 S4 A8])
(reg/f:SI 6 bp)) 28 {*pushsi2} (nil)
(nil))
(insn/f 21 20 22 (set (reg/f:SI 6 bp)
(reg/f:SI 7 sp)) 34 {*movsi_1} (nil)
(nil))
(insn/f 22 21 23 (parallel [
(set (reg/f:SI 7 sp)
(plus:SI (reg/f:SI 7 sp)
(const_int -8 [0xfffffff8])))
(clobber (reg:CC 17 flags))
(clobber (mem:BLK (scratch) [0 A8]))
