--- Comment #4 from Mikael Pettersson <mikpe at it dot uu.se> 2012-10-18 19:43:02 UTC --- The test case started failing with r189790: http://gcc.gnu.org/ml/gcc-cvs/2012-07/msg00695.html That patch merely enabled insn splitting at -O0, so I suspect it exposed a latent problem in the back-end, consistent with Måns' analysis.
