- Subject: gcc-2.95: Please add big-endian arm (armeb) support
- From: Lennert Buytenhek <buytenh+debian@wantstofly.org>
- Date: Thu, 27 Oct 2005 18:46:58 +0200

Package: gcc-2.95
Severity: wishlist
Tags: patch
The attached patch adds big-endian arm support to gcc-2.95. It's
more-or-less the same as its gcc-4.0 counterpart: teach the debian
build scripts about 'armeb', and patch gcc so that it defaults to
big-endian.
Since gcc-2.95 is so old, I haven't bothered with making a patch that
detects the endianness at configure time -- instead, if we're being
built for the armeb arch, a patch is applied that just hardcodes the
default endianity to big-endian. Please let me know if this is not
acceptable.
Together with the patches for #323512 and #336057 this allows for a
fully native build of gcc-2.95 on a big-endian arm system.
