uwe f482b86d5d gcc4 generated extremely unoptimal code for shifts of 64-bit ints on SuperH. Pull over a fix from gcc 4.1 branch. ok mrg@ Author: sayle Date: Fri Jul 21 13:22:31 2006 New Revision: 115644 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=115644 Log: PR middle-end/28283 * expmed.c (expand_shift): Additionally check that the shift_cost is not MAX_COST and that INTVAL(op1) is less than MAX_BITS_PER_WORD before implementing a LSHIFT_EXPR as a sequence of additions. * config/sh/sh.c (shift_costs): Return MAX_COST to inform the middle-end that DImode shifts need to be synthesized by expand.

Organization of Sources:

This directory hierarchy is using a new organization that
separates the GNU sources from the BSD-style infrastructure
used to build the GNU sources.  The GNU sources are kept in
the standard GNU source tree layout under:

	dist/*

The build infrastructure uses the normal BSD way under:

	lib/*
	usr.bin/*

The makefiles in the above hierarchy will "reach over" into
the GNU sources (src/gnu/dist) for everything they need.


Maintenance Strategy:

The sources under src/gnu/dist are generally a combination of
some published distribution plus changes that we submit to the
maintainers and that are not yet published by them.  There are
a few files that are never expected to be submitted to the FSF,
(i.e. BSD-style makefiles and such) and those generally should
stay in src/gnu/lib or src/gnu/usr.bin (the BSD build areas).

Make sure all changes made to the GNU sources are submitted to
the appropriate maintainer, but only after coordinating with the
NetBSD maintainers by sending your proposed submission to the
<tech-toolchain@NetBSD.org> mailing list.  Only send the changes
to the third-party maintainers after consensus has been reached.
