How, i can work with read-rtl.c

[Klaus Friedrich]

Hallo,

my name is Klaus Friedrich. For my diploma thesis, i will work with the 
gcc4.1 internals. I would like to extract information about the RTL
language. So i try to use for exapmle GET_CODE(x) and PUT_CODE(x, 
newcode) funtions. For this purpose i will read a RTX from a
external ASCII file, like ....00.expand.

Please tell me, how i can use read_rty(), print_rtx() functions, to get 
a RTX object!

Can you tell me, how i can use the read-rtl.c and rtl.h in a short C/C++ 
ProgramExample, because i don't
know, how i can include this files from the gcc source code dir.


Thank You very much!!!
