Also, use 1/0 intead of h/l (e.g. a1 instead of ah), as this keeps consistency with other primitives and allows for naming that works with double word, triple word and quadruple word inputs/outputs.

Otherwise the first instruction can overwrite the inputs, which then results in the second instruction producing incorrect value. 2023-01-31T05:57:08+00:00 jsing 2023-01-31T05:57:08+00:00 urn:sha1:679f8c4daf382efeee02c91cc81af88941779b9f These should work, but are currently untested and disabled. ok tb@ 2023-01-20T10:04:34+00:00 jsing 2023-01-20T10:04:34+00:00 urn:sha1:481d4dbec5e67fc8e767c554b19a84590c6c755f This will provide a location for machine specific defines, prototypes and inline functions. ok tb@
