propagated changes of Wednesday Dec 23 2009 - Saturday Dec 26 2009
from the Nov2009 branch to the development trunk
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/12/23 - sjoerd: compiler/mil/mil_opt.c,1.37.6.1
We expect assigns_to to fit into the stmts array (size OPT_STMTS) (I think).
Added assert to help Coverity.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/12/23 - sjoerd: compiler/mil/mil_opt.c,1.37.6.2
We need assert.h now that we have an assertion.
