Subject: [PATCH] tile: default to little-endian in bits/endian.h
Date: Wed, 12 Jun 2013 20:57:00 -0000 [thread overview]
Message-ID: <201306122057.r5CKvRl0008808@farm-0002.internal.tilera.com> (raw)

* sysdeps/tile/bits/endian.h (__BYTE_ORDER): Default to little.
This turns out to be helpful when doing a from-scratch cross-compile of
gcc and glibc, since you can then do "make install-headers" in glibc
even before you have a functioning tile gcc.
This was pointed out by Mike Frysinger (cc'ed).
David, Carlos, I'd like to also backport this to glibc 2.17 and 2.16,
to make cross-building easier there. It applies to 2.15 as well, but
I'm not sure how far back it makes sense to go with this kind of thing.
