Editor modes that invoke the goimports command on temporary copies
of actual source files will need to invoke goimports -srcdir now to say
where the real source directory is. Otherwise goimports will not consider
vendored or internal packages when looking for new imports.
In lieu of a test for cmd/goimports (because it has no tests),
a command transcript:
$ cd /tmp
$ cat x.go
package p
var _ = hpack.HuffmanDecode
$
$ GOPATH= goimports < x.go
package p
var _ = hpack.HuffmanDecode
$ GOPATH= goimports x.go
package p
var _ = hpack.HuffmanDecode
$
But with the new flag:
$ GOPATH= goimports -srcdir $GOROOT/src/math < x.go
package p
import "golang.org/x/net/http2/hpack"
var _ = hpack.HuffmanDecode
$ GOPATH= goimports -srcdir $GOROOT/src/math x.go
package p
import "golang.org/x/net/http2/hpack"
var _ = hpack.HuffmanDecode
$
The tests in this CL and the above transcript assume that
$GOROOT/src/vendor/golang.org/x/net/http2/hpack exists.
It did in 40a26c9, but it does not today.
It will again soon (once Go 1.7 opens).
For golang/go#12278 (original request).

Before, "bundle -help" printed only one not particularly useful line:
Usage of bundle:
and "bundle" printed a bit more but not a standard usage message:
bundle: Usage: bundle package dest prefix
Arguments:
package is the import path of the package to concatenate.
dest is the import path of the package in which the resulting file will reside.
prefix is the string to attach to all renamed identifiers.
And most of that output belonged in (but was missing from) the doc comment,
which leaned heavily on the reader inferring usage from one example.
While fixing all this, I ended up dropping "dest" and "prefix" as required
arguments: perfectly good defaults can be inferred in the common case
where the bundle is intended for the current directory. The defaults can be
overridden with the new -dst and -prefix option.
I corrected a TODO about not assuming the package name could be
derived from the destination import path. Like -dst and -prefix, the
default package name can be inferred from the current directory,
but there is also a new -pkg option to override the default if needed.
I added a -o option to specify the destination output file (standard output
is still the default output). One benefit of -o is that it makes the bundle
commands self-contained in the sense of not needing a shell.
That in turn makes them suitable for use with "go generate", so when -o
is specified the bundle output now includes a "//go:generate" comment
for updating the bundle mechanically.
To keep bundle working for net/http's use case, I added a -importmap
option to specify additional import rewrites (net/http needs the http2
import of golang.org/x/net/http2/hpack rewritten to begin with internal/golang.org).
The net effect of all of this is that the first two lines at the top of
net/http/h2_bundle.go will change from:
// Code generated by golang.org/x/tools/cmd/bundle command:
// $ bundle golang.org/x/net/http2 net/http http2
to
// Code generated by golang.org/x/tools/cmd/bundle.
//go:generate bundle -o h2_bundle.go -prefix http2 -import golang.org/x/net/http2/hpack=internal/golang.org/x/net/http2/hpack golang.org/x/net/http2
and net/http's copy of http2 can now be updated by "go generate"
instead of by copying and pasting commands from source code to shell.
For an experiment I am doing with cmd/dist bundling archive/zip,
the header is even shorter and makes a better demonstration of the
power of the defaults:
// Code generated by golang.org/x/tools/cmd/bundle.
//go:generate bundle -o zip.go archive/zip
New usage message, printed by "bundle -help" and "bundle":
Usage: bundle [options] <src>
-dst path
set destination import path (default taken from current directory)
-import map
rewrite import using map, of form old=new (can be repeated)
-o file
write output to file (default standard output)
-pkg name
set destination package name (default taken from current directory)
-prefix p
set bundled identifier prefix to p (default source package name + "_")
See CL for new doc comment.
Following this CL I will send a CL updating the two-line header in net/http/h2_bundle.go
to match the new usage of the bundle, whatever that ends up being.

As an optimization, the callers and callstack queries now avoid the
relatively costly pointer analysis in some common cases:
The callers of a function that is never address-taken can be enumerated
directly from the SSA representation.
Similarly, the callstack can be computed initially by ignoring dynamic
call edges; we run the pointer analysis only if no path is found in this
partial callgraph. As a bonus, this also causes the tool to
preferentially report all-static callpaths.
A callers query on fmt.Errorf now completes in 3 seconds instead of 8,
and a callstack query completes in 2 seconds instead of 8.
The new code is covered by the existing tests.

For the default build.Context, the Package.Goroot flag indicates when a
package was loaded from the standard library. Until now, the loader
used it to enable the typechecker's intrinsics for the "unsafe" package.
This seemed like a good check, but it is troublesome for clients that
use a nonstandard build.Context. For example, if a client defines
nonstandard Context hooks that load all packages, whether standard or
user-defined, from a flat sstable, there is no way for those hooks to
indicate which packages should have this flag set and which not. As a
result the contents of the "unsafe" package directory are treated as Go
source code when they are merely documentation.

Import path is a '/'-separated path. FromDir documentation says
on return, root is the import path corresponding to the root of
the repository. On Windows and other OSes where os.PathSeparator
is not '/', that wasn't true since root would contain characters
other than '/', and therefore it wasn't a valid import path
corresponding to the root of the repository. Fix that by using
filepath.ToSlash.
Add test coverage for root value returned from FromDir, it was
previously not tested.
Additionally, remove a dubious statement from the documentation
"(thus root is a prefix of importPath)". There is no variable
importPath that is being referred to. It's also redundant and
confusing. Without it, the description of root value matches

// Root is the import path corresponding to the root of the
