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!

-dr does dump the RTL for the entire module you are compiling. There is
no RTL for libraries if that is what you are looking for. If your
question is something else, then please give a testcase.

We have only the sources and the documentation.

See the section "RTL generation" in the gcc/doc/passes.texi file.
