Segher Boessenkool d839f53b7d rs6000: New attributes for load/store: "sign_extend", "update" and "indexed"
The new attributes replace the instruction types *_ext*, *_u, *_ux.

This simplifies all code that does not care about the addressing modes,
putting the burden on the code that does care (mostly the scheduling
descriptions for certain CPUs).

It fixes a few minor bugs in the process.

The "update" and "indexed" attributes are automatic for any insn that
has a MEM as operand 0 or 1.  Other insns have to set it manually, if
they do not like the default (which is "no").  Insns that are type
load/store/fpload/fpstore but have fewer than two operands need to set
it too, or the compiler will crash.  There are very few of those.

This tries not to change semantics anywhere; in particular, the string
and multiple instructions set both "update" and "indexed" (although
they are neither).

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
