svn commit: trunk/buildroot/package/gnuconfig: patches

[lethal at uclibc.org]

Author: lethal
Date: 2005-11-21 12:14:49 -0800 (Mon, 21 Nov 2005)
New Revision: 12457

Log:
Add support for sh2a and sh4a big endian (ie, targets that reflect
hardware that actually exists -- never something to deter gcc folk
though). Now ISA tuning has a chance of producing a bootable kernel,
gcc code generation notwithstanding..

+gnuconfig seems intent on only supporting superfluous targets that don't
+represent any real hardware (such as sh2a LE). GCC in its infinite wisdom is
+also incapable of supporting tuning for other variants in a sensible fashion.
+
+As such, we still need to be able to support such useful targets as
+sh2a_nofpueb in order to not only get the byte order right, but also to
+support -m2a-nofpu tuning from the kernel (though we tend to do this through
+-Wa,-isa= instead, as the binutils people do a much better job of not screwing
+up their config code every other day. Way to go config.gcc..).
+
+The fact that the sh variant matching is the ugliest out of any of the other
+architectures doesn't seem to deter GCC folk from their well thought out and
+brilliantly managed config target list.
