 OK, that's because Linux returns S242 by the sret mechanism instead of  
 as an i64.  What's I'd like to do to preserve the sense of the test is  
 grep for retval | memtmp, but I'm not sure how to do that portably.   
 Does this work for you?
 
 // RUN: %llvmgxx -S -O0 -emit-llvm %s -o - | grep {retval\\|memtmp} |

It works for me so I've committed it.

Thanks!

Duncan.

Ciao,
