Include <sys/endian.h> after defining whether where are little- or big-endian. i386, pc532 and vax still include <machine/byte_swap.h> and define macros for the {n,h}to{h,n}*() functions. mips also defines some endian-independent assembly-code aliases for unaligned memory accesses. 1999-08-21 09:53:50 +04:00			`#include <sys/endian.h>`
Add bi-endian support to mips locore, <mips/endian.h>, and mips_opcode.h. Derived from a change request (PR port-mips/4277) from Tsubai Masanari, (tsubai@iri.co.jp). 1997-10-17 08:43:57 +04:00
