[GNAT] New switch to disable short-circuit optimizations

Tuesday January 29, 2008

The new GCC switch -fno-short-circuit-optimize disables optimization of short-circuit operations (AND THEN/OR ELSE) so that explicit jumps remain in the generated code. This can make decision coverage of object code more straightforward (e.g. MCDC testing required by DO-178B level A).
