Please find an updated patch below, addressing most of Dan's criticism: - Support for NetBSD and OpenBSD has been removed since its status is unknown. - Definitions of EXPLICIT_SIGN_EXTEND, VIRT_ADDR_VARIES and other unneccessary macros have been deleted. However, I've left both files m/sh3el.h and m/sh3eb.h in for now, since conditional definition of WORDS_BIG_ENDIAN would probably require an autoconf test for endian.h. And then it's IMHO preferable to use AC_C_BIGENDIAN instead. >> dnl This could be used for targets which can have both byte sexes. >> dnl We could presumably replace the hardwired WORDS_BIG_ENDIAN generally. >> dnl AC_C_BIGENDIAN > This would be a welcome change, indeed.
