Eric, David Brenner noticed that sparc little-endian support is
a candidate for deprecation or deletion. I support the latter,
we have no real OS targets supporting it and sparclet support
was removed in 2003 (!!!).
In fact, only sp64-elf.h even tries to override the endianness
macros correctly, and I can guarentee you we have big-endian
assumptions in some of our subregging in the MD file.
It's really not possible that this is being used by anyone, as far as
I can see. So let's just kill it all off.
Any objections?
gcc/
* config/sparc/little-endian.opt: Delete.
* config.gcc: Remove references to config/sparc/little-endian.opt
* doc/invoke.texi: Remove documentation of -mlittl-endian on sparc.
* config/sparc/linux64.h: Delete references to -mlittle-endian.
* config/sparc/netbsd-elf.h: Likewise.
* config/sparc/openbsd64.h: Likewise.
* config/sparc/sparc.h: Likewise.
* config/sparc/sp64-elf.h: Likewise and delete overrides for
BYTES_BIG_ENDIAN and WORDS_BIG_ENDIAN.
* config/sparc/sparc.c (dump_target_flag_bits): Remove reference
to MASK_LITTLE_ENDIAN.
* config/sparc/sparc.opt (Mask(LITTLE_ENDIAN)): Delete.
