by a reverse-conditional branch over a branch or jump by a reverse-conditional branch over a branch or jump
To reduce the number of terminals, some instructions that have operands of
equal size are coded with an X instead of b, w, or l; these instructions
have the size in the high order word of the valu field. This is needed
because some yacc versions do not accept grammars with more than 127
terminal symbols.
