Two sources of information come to mind:

1. For general "warnings" of this type, you may wish to try the Ada
Quality & Style Guide,
which is available from

   http://sw-eng.falls-church.va.us/AdaIC/

For example, using the handy search feature for "enumeration
representation", one finds the statement:

  "Only if absolutely necessary, use representation clauses to match
requirements of external devices."

2. Check with your compiler vendor for available tool-specific
documentation. TI/Tartan compilers, for example, come with a fairly good
section on writing for optimization, and include a list of bugs
(including those affecting optimization). If your vendor can't, or
won't, provide such information, and you really need it, then consider a
change of vendor!
