--- Comment #5 from Roger Sayle <roger at nextmovesoftware dot com> --- I'll add this testcase to the testsuite, when I apply a corrected version of my QImode offset patch to mainline. On the bright side, we'll be generating more efficient code for gmp's refmpn_tstbit by using the x86's bt instruction (it just needs to use setc not setnc in this case).
