+/* These define the size of main memory for the simulator.
+
+   Note the size of main memory for the H8/300H is only 256k.  Keeping it
+   small makes the simulator run much faster and consume less memory.
+
+   The linker knows about the limited size of the simulator's main memory
+   on the H8/300H (via the h8300h.sc linker script).  So if you change
+   H8300H_MSIZE, be sure to fix the linker script too.
+
+   Also note that there's a separate "eightbit" area aside from main
+   memory.  For simplicity, the simulator assumes any data memory reference
+   outside of main memory refers to the eightbit area (in theory, this
+   can only happen when simulating H8/300H programs).  We make no attempt
+   to catch overlapping addresses, wrapped addresses, etc etc.  */
