           Summary: gccas is misoptimizing bison-1.875/src/scan-gram.c
           Product: tools
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gccas
        AssignedTo: sabre at nondot.org
        ReportedBy: gaeke+bugs at uiuc.edu


One of the persistent bison failures goes away if I recompile
bison-1.875/src/scan-gram.c with native gcc, or with llvm-native-gcc
-Wa,-disable-opt. I haven't had time to track it down further than this...I hope
I can bugpoint it soon. The test failure is the "scanner torture test" at the
end of tests/input.at.
