newbie: RTL syntax

[Iman Narasamdya]

Hi!

I would like to translate RTL representation to another more readable 
representation, e.g.:
<some RTL representation>
|
|
V
r60 <- r108 - 23
if r60 =< 0 then goto 25
goto 53

25: goto 53

53: r24 <- 0

Without touching the source of RTL generator, it means that I have to 
know the syntax of RTL representation, in order to parse it. I have 
looked at the gcc internal manual, but it doesn't describe the syntax 
completely. Is there any description of the syntax of RTL representation 
out there? Or does anyone have RTL parser :-) ?

Cheers.
