Hi all, I used llvm-gcc (llvm version 2.7) to transform a linux network driver program (for example: linux/drivers/net/zoro8390.c) to the IR form with the command: "llvm-gcc -D__GNUCC -E -emit-llvm -I../../include zorro8390.c -S" under the drivers/net directory. It didn't give the resulting IR (i.e. zoro8390.s) and it printed out a modified program, which it looked like the definitions for functions, macros and other stuff from other files are all added or expanded for my target program. How could I get the desired IR for the driver? Thank you very much! Regards, Daniel -------------- next part -------------- An HTML attachment was scrubbed...

It preprocesses the file.> How could I get the desired IR for the driver? Thank you very much!You have the two other flags that matter, -S and -emit-llvm. Try removing -E and see whether that works.

Thank you very much for both of you! I tried to compile the program without the -E and then I got lots of compile errors of missing headers and definitions. I'm trying to eliminate them now.
