From: Bean Huo <beanhuo@xxxxxxxxxx>
Current EM macro definition, we use stringize operator '#', which turns
the argument it precedes into a quoted string. Thus requires the symbol
of __print_symbolic() should be the string corresponding to the name of
the enum.
However, we have other cases, the symbol and enum name are not the same,
we can redefine EM/EMe, but there will introduce some redundant codes.
This patch is to remove this restriction, let others reuse the current
EM/EMe definition.
