This upgrades all of libgo other than the runtime package to
the Go 1.4 release. In Go 1.4 much of the runtime was
rewritten into Go. Merging that code will take more time and
will not change the API, so I'm putting it off for now.
There are a few runtime changes anyhow, to accomodate other
packages that rely on minor modifications to the runtime
support.
The compiler changes slightly to add a one-bit flag to each
type descriptor kind that is stored directly in an interface,
which for gccgo is currently only pointer types. Another
one-bit flag (gcprog) is reserved because it is used by the gc
compiler, but gccgo does not currently use it.
There is another error check in the compiler since I ran
across it during testing.
gotools/:
* Makefile.am (go_cmd_go_files): Sort entries. Add generate.go.
* Makefile.in: Rebuild.

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.
