879a1c6a72 godefs: delete, replaced by cgo -godefs
Godefs was a C program that ran gcc and then parsed the
stabs debugging information in the resulting object file to
generate C or Go code for bootstrapping as part of
package runtime or package syscall.

Cgo does the same work, but using the dwarf debugging
information.  Add -godefs and -cdefs options to cgo that
mimic godefs's output, albeit with different input
(a Go program, not a C program).

This has been a "nice to have" for a while but was forced
by Apple removing stabs debugging output from their
latest compilers.

Fixes #835.
Fixes #2338.

17105870ff 6l: add MOVQ xmm_reg, xmm_reg
Added handler for:
        MOVQ xmm_reg, xmm_reg/mem64
        MOVQ xmm_reg/mem64, xmm_reg
using native MOVQ (it take precedence above REX.W MOVD)
I don't understood 6l code enough to be sure that my small changes
didn't broke it. But now 6l works with MOVQ xmm_reg, xmm_reg and
all.bash reports "0 unexpected bugs".

There is test assembly source:
MOVQ    X0, X1
MOVQ    AX, X1
MOVQ    X1, AX
MOVQ    xxx+8(FP), X2
MOVQ    X2, xxx+8(FP)

and generated code (gdb disassemble /r):

0x000000000040f112 <+0>:   f3 0f 7e c8        movq  %xmm0,%xmm1
0x000000000040f116 <+4>:   66 48 0f 6e c8     movq  %rax,%xmm1
0x000000000040f11b <+9>:   66 48 0f 7e c8     movq  %xmm1,%rax
0x000000000040f120 <+14>:  f3 0f 7e 54 24 10  movq  0x10(%rsp),%xmm2
0x000000000040f126 <+20>:  66 0f d6 54 24 10  movq  %xmm2,0x10(%rsp)

Fixes #2418.

f2dc50b48d html,bzip2,sql: rename Error methods that return error to Err
There are three classes of methods/functions called Error:

a) The Error method in the just introduced error interface
b) Error methods that create or report errors (http.Error, etc)
c) Error methods that return errors previously associated with
   the receiver (Tokenizer.Error, rows.Error, etc).

This CL introduces the convention that methods in case (c)
should be named Err.

The reasoning for the change is:

- The change differentiates the two kinds of APIs based on
  names rather than just on signature, unloading Error a bit
- Err is closer to the err variable name that is so commonly
  used with the intent of verifying an error
- Err is shorter and thus more convenient to be used often
  on error verifications, such as in iterators following the
  convention of the sql package.

d26144be29 gofix: make fix order implicit by date.
This partially undoes 8fd7e6d070c8, but preserves its semantics.
More importantly, it results in the data about each fix being
decentralised, which makes it easier for new fixes to be added,
and other gofix users to slot new fixes in.

It also adds some useful metadata that could be used in the future.

To make the error fix more useful, expand typecheck to gather

typecheck indirect and index of named types, and collect information
about assignment conversions.

Also, change addImport to rename top-level uses of a to-be-imported
identifier to avoid conflicts.  This duplicated some of the code in
the url fix, so that fix is now shorter.

7b04471dfa gopack: change archive file name length back to 16
This CL grew the archive file name length from 16 to 64:

        changeset:   909:58574851d792
        user:        Russ Cox <rsc@golang.org>
        date:        Mon Oct 20 13:53:56 2008 -0700

Back then, every x.go file in a package became an x.6 file
in the archive.  It was important to be able to allow the
use of long Go source file names, hence the increase in size.

Today, all Go source files compile into a single _go_.6 file
regardless of their names, so the archive file name length
no longer needs to be long.  The longer name causes some
problems on Plan 9, where the native archive format is the
same but with 16-byte names, so revert back to 16.
