about RTL

[王 逸]

Hi, I'm thinking of patching GCC so that the compiler may automatically 
insert some instructions in the final excutable objects.
 
I would like to do this at the RTL generation phase. But I've some 
questions:
 
1. I used "gcc -dr *.c" command to dump RTL code, but only got the RTL code 
for main function. 
   (It begins with "; Main Function", so I guess it does not express the 
whole program.)
   How can I get the whole program's RTL representation?
2. I'm not familiar with GCC and RTL, how can I get some resources about 
them? 
   (except GCC internals, I've already got one.)
3. Which files are related to RTL generation in the GCC source? I'd like to 
read some of them.
 
thx for reading!
