/* machine map, in words. the default has the code area, the compiler tables,
   the genome and the stacks first (PW words in all) and the heap last: it
   starts at PW and grows at run time, up to MW words of memory. MW is the
   host's memory size; the array behind it is untouched until the heap grows
   into it. a smaller board is a different build: src/tools/genmap writes a
   directory whose memmap.h and genome agree, and the C cores are compiled
   against that directory. do not edit the numbers by hand in one file only.

   include genome.h before this header when both are in the translation
   unit. the linked image's GORG then wins; it has to be the same value
   this header would have defined.

   PW is the first word past the initial stacks. emitted code can add heap
   segments, and native code-address tables grow with those reservations.
   MW bounds data addresses. a fixed map (HEAP_GROW 0) has MW == PW.

   DSLIM and RSLIM are the interpreter's stack checks. a straight-line
   block can push about 1024 words after the check, which is why the data
   limit sits 1100 words above DSLO. the genome's prologue checks the current frame segment and adds another
   segment when needed. */
