here is my command line:

and its output:

I've tested the attached patch, and I find that it succeeds in preventing the
current missed optimizations in structs passed by value from affecting 128-bit

The patch posted in Bug 20020 prevents missed optimization for 128-bit

The cutdown test case only shows the difference in code generation (between
-O2 and -O2 -g) in big-endian mode. The original larger test case had
