     1.8 ++ * Reporter: marcus@mc.pp.se
     1.9 ++ * Summary: [3.3/3.4 regression] [SH] optimizer generates faulty array indexing
    1.10 ++ * Description:
    1.11 ++ * The address calculation of an index operation on an array on the stack 
    1.12 ++ * can _under some conditions_ get messed up completely
    1.13 ++ *
    1.14 ++ * Testcase tweaked by dank@kegel.com
    1.15 ++ * Problem only happens with -O2 -m4, so it should only happen on sh4,
    1.16 ++ * but what the heck, let's test other architectures, too.
    1.17 ++ * Not marked as xfail since it's a regression.
