--- Comment #6 from Kyle Moffett <Kyle.D.Moffett at boeing dot com> 2011-11-02 18:24:02 UTC --- Created attachment 25692 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25692 Archive of RTL dumps of failing testcase built with "-Os" I spent some time looking through the RTL dump. It looks like the stack references first show up in 194r.split2, but I couldn't understand enough of what I was looking at to match it up with the assembly output or figure out where the CFI information went wrong. I've attached a tar.gz of the RTL dumps in case that helps isolate the issue. Cheers, Kyle Moffett
