++/* PR optimization/10392
++ * Reporter: marcus@mc.pp.se
++ * Summary: [3.3/3.4 regression] [SH] optimizer generates faulty array indexing
++ * Description:
++ * The address calculation of an index operation on an array on the stack
++ * can _under some conditions_ get messed up completely
++ *
++ * Testcase tweaked by dank@kegel.com
++ * Problem only happens with -O2 -m4, so it should only happen on sh4,
++ * but what the heck, let's test other architectures, too.
++ * Not marked as xfail since it's a regression.
