This directory contains the default EM_CODE(3L) interface. That is :
1) message-instruction are ignored.
2) pseudo-instruction are almost machine independent, so they are
implemented completely. *)
3) storage-instruction are almost machine independent, so they are
implemented completely. *)
4) The other EM instructions generate a "not implemented"
message.
The file "pseudovars.c" contains two global variables. 'locals_created' tells if
the prolog is exected or not. 'Busy' tells if the code expander is running
or not.
*) The necessary constants should be defined by the table writer.
