llvm dev - Jun 2013 - [LLVMdev] Problem with DragonEgg 3.3rc2 on Fedora 19 Beta

I'm the package maintainer for DragonEgg for Fedora.  I've just tried to
update the DragonEgg package for Fedora 19 beta, which uses gcc 4.8.0.

I had to modify the DragonEgg Makefile because llvm-config --libs is
generating the names of the static libraries, while I need to link to the
dynamic library (libLLVM-3.3.so).  I don't think this is the cause of my
problem, but I suppose I could be wrong.

Anyhow, I have a very simple C program.  When I compile it with gcc (on
Fedora 19 beta, x86_64), it works fine.  When I compile it with gcc
-fplugin=dragonegg, I get an executable that doesn't seem to execute the
printf inside the loop.

The C program, executables from gcc and gcc -fplugin=dragonegg, and
disassemblies of the .o files can be found here:
        http://fedorapeople.org/~brouhaha/dragonegg/

If anyone would care to take a look at this, I can provide account
credentials to ssh into the system I'm using.

Thanks!
Eric

what version of gcc are you loading the plugin into?

Ciao, Duncan.

your program has a mistake in it, you should initialize i with i=0 not with i=i
here:

   for (i = i; i <= 30; i++)

Ciao, Duncan.
