--- Comment #27 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to H.J. Lu from comment #26) > But when this splitter fails, no other splitters will be tried. Bah. This is clearly an implementation bug in the split pass. I don't think we have to work around it, the infrastructure bug should be fixed instead. Can you please open a new bug about it? I propose to go ahead and commit my patch, which is already accumulating several semi-related fixes and improvements. The patch will probably expose an optimization problem in the splitting pass, so we will have a testcase to illustrate the problem.
