New description:

 The primops testcase for `timesWord2#` in `T9430` fails on ARM.
 {{{
 cd ./primops/should_run && ./T9430    </dev/null > T9430.run.stdout 2>
 T9430.run.stderr
 Wrong exit code (expected 0 , actual 1 )
 Stdout:

 Stderr:
 T9430: Error for timesWord2# : Expected 1 and 0 but got 0 and 0
 CallStack (from ImplicitParams):
   error, called at T9430.hs:55:22 in main:Main
 }}}
 It looks like this is probably an 32-bit LLVM code generator bug although
 I have yet to confirm this.
