First, we have found several bugs in GCC as a result of "caring about
the assembly". Lets agree that it's an indication that someone is doing
something wrong.
The reason I'm trying to disable this optimization is because it causes
the code to be too big to fit onto the available ROM on which the code
needs to be flashed. The X86 version I gave here shows the problem, but
is no the platform on which the problem was diagnosed.
