Expected output when runing lli on hello.ll (here using -mattr=+v6)
xerxes at xerxes:/sd/llvm-configure/test/ExecutionEngine/Output$ lli -mattr=+v6 <
hello.ll.tmp.bc Hello World

Actual output using -mattr=+v6t2
xerxes at xerxes:/sd/llvm-configure/test/ExecutionEngine/Output$ lli -mattr=+v6t2
< hello.ll.tmp.bc

The same happens using -mattr=+v7a

-mattr=+v7a < hello.ll.tmp.bc
