New targets: shle-elf / sh64le-elf
- From: Joern Rennecke <joern dot rennecke at superh dot com>
- To: gcc-patches at gcc dot gnu dot org, binutils at sources dot redhat dot com

- Subject: New targets: shle-elf / sh64le-elf
- Organization: SuperH UK Ltd.
I have checked in the attached patch, which allows to configure
for SH so that the default endianness is little endian.
Right now, only the shle-elf configuration is operational, for
the sh64le-elf configuration, I'm waiting for approval of a config.sub
patch.
