[LLVMdev] comparing .o files from different build trees

I'm trying to write a script for checking whether the compiler recursed
properly.
rkotler at mipsswbrd002:~/slave/recurse3be/build$ find . -name "*.o" -exec
cmp '{}' ../../recurse2be/build/'{}' \; |& tee foo.txt
Is anyone else doing this?
There 2 compilers, recurse 2 and recurse3 that in principle should be
identical.
Obviously if there is date and time information, miscompares can occur.
