* ILP32 uses a version of the ppc64 abi with sizeof(void*)==sizeof(long)==4.
- * To support this, code which needs the size of a pointer needs to use
- * sizeof (gpointer), while code which needs the size of a register/stack slot
- * needs to use SIZEOF_REGISTER.
+ * To support this, code needs to follow the following conventions:
+ * - for the size of a pointer use sizeof (gpointer)
+ * - for the size of a register/stack slot use SIZEOF_REGISTER.
+ * - for variables which contain values of registers, use mgreg_t.
+ * - for loading/saving pointers/ints, use the normal ppc_load_reg/ppc_save_reg ()
+ * macros.
+ * - for loading/saving register sized quantities, use the ppc_ldr/ppc_str
+ * macros.
+ * - make sure to not mix the two kinds of macros for the same memory location,
+ * since ppc is big endian, so a 8 byte store followed by a 4 byte load will
+ * load the upper 32 bit of the value.
+ * - use OP_LOADR_MEMBASE/OP_STORER_MEMBASE to load/store register sized
+ * quantities.
