// RUN: %llvmgcc -S %s -o - | llvm-as -o /dev/null

/* This triggered a problem in reload, fixed by disabling most of the 
 * steps of compilation in GCC.  Before this change, the code went through
 * the entire backend of GCC, even though it was unnecessary for LLVM output
 * now it is skipped entirely, and since reload doesn't run, it can't cause
 * a problem.
