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.
