gcc and VCG

[Marcio de Oliveira Buss]

	Folks,

 	Could someone please help me??
 
 	I have installed the vcg tool under a Linux system. The
  installation was ok, but when I try to visualize some graphs,
  the system has broken.
 	After I compile a file called jccoefct.c, which
  belongs to a JPEG benchmark, the result file jccoefct.c.13.life.vcg
  contains some parameters that seems dont be recognized by the
  VCG tool. The attribute "hidden" appears in the file 
  jccoefct.c.13.life.vcg, and also appears in the grammar of the
  VCG tool. However, I am trying to load this file in the
  xvcg I have installed, and xvcg always tells me:
 
  "T_Co_hidden currently not implemented!"
 
 	One piece of the file jccoefct.c.13.life.vcg is shown
  below:
 

  graph: {
  port_sharing: no
  graph: { title: "start_iMCU_row"
  folding: 1
  hidden: 2
  node: { title: "start_iMCU_row.0" }
  graph: {
  title: "start_iMCU_row.BB0"
  folding: 1
  color: lightblue
  label: "basic block 0"
 
  edge: { sourcename: "start_iMCU_row.0" targetname: "start_iMCU_row.96"
  col$node: {
    title: "start_iMCU_row.96"
    color: lightgrey
    label: "note 96
   NOTE_INSN_BASIC_BLOCK"
  }
  edge: { sourcename: "start_iMCU_row.96" targetname: "start_iMCU_row.4" }
  node: {
    title: "start_iMCU_row.4"
    color: green
    label: "insn 4
  (set (mem/f:SI (reg:SI 0 $0) 0)
      (reg:SI 4 a0))
  "
  }
 
 
 	I will be glad if someone could help me.
 
 	Best regards,
 
 	Marcio Buss.
