In the go build system, test packages and executables do not have a
name distinct from the package under test; they are implied, so
"go test fmt" means build those packages but "go build fmt" does not.
This change adds a Tests boolean option to indicate that implied
tests are desired during pattern expansion.
It has no effect on build systems that have explicit names
for tests, such as Blaze/Bazel.
The gopackages diagnostic tool now has a -test flag.

This package defines a new API for applications that need information
about Go packages, such as their source files, tests, dependencies,
and (optionally) typed syntax trees. It is intended to replace both
go/build and golang.org/x/tools/go/loader with an API that is simpler
yet supports a range of build systems including 'go build', vgo,
Bazel, and Blaze.
This CL contains the API, the "go list"-based implementation, and some
basic tests. More tests, more features as described in doc.go, and
implementations for bazel and blaze will follow.
Read doc.go for orientation and a list of open questions.

Ideally we would like to have this functionality in the std lib

Before this change, astutil would only do a prefix match of a new import
with all the existing ones, to try to place it in the correct group. If
none was found, the new import would be placed at the beginning of the
first import group.
This works well for new std imports, but it doesn't work well for new
third-party packages that don't share any prefix with any of the
existing imports.
Example:
import (
"time"
"github.com/golang/snappy"
)
When adding "golang.org/x/sys/unix" with astutil.AddImport, the import
is inserted as follows:
import (
"golang.org/x/sys/unix"
"time"
"github.com/golang/snappy"
)
And goimports reorganizes the imports to separate std and third-party
packages:
import (
"time"
"golang.org/x/sys/unix"
"github.com/golang/snappy"
)
We usually don't want to introduce a new import group; in most cases,
the desired behavior is separating std from third-party packages.
With this CL, new imports that don't share prefix with any existing ones
will be placed with the first group of third-party imports, if any
exist. If no third-party import group exists, a new one will be added.
In the case of our example above, this will be the new outcome:
import (
"time"
"github.com/golang/snappy"
"golang.org/x/sys/unix"
)

https://go-review.googlesource.com/37157 introduced a bug that caused
some live φ-nodes to be removed from the CFG. The cause was that
reachability traversal considered edges only among "new" φ-nodes
(those introduced during SSA renaming) but not existing φ-nodes from
&& and || expressions. The fix is to mark existing phis, and thus
other phis reachable from them, as live. We also clear the Phi.block
field when eliminating a φ-node.
Also, during reachability, we treat DebugRef instructions as roots
like any other non-Phi instruction. This eliminates a related known
bug whereby the operand of a DebugRef may be a dead φ.
This change also adds a sanity check that all operands of an SSA value
that are themselves instructions must belong to a block. The sanity
check would fail 7 times on the standard library without the fix.

If an import path is deleted there might be a blank line-sized hole:

It'll merge the black hole with the last line to change it to:

However the import declaration might be in the following form as well:
import (

Whic means after deleting the import path, it changes to:

In this case it still tries to merge the line with a non existing line,

The existing API for querying values only allows directly querying
pointer-like values, or pointers to such values. The new, extended
queries make it possible to destructure values and access arbitrarily
nested pointers, such as fields in structs, or specific values in
tuples.
We use single Go expressions as the queries, which we further restrict
to a subset of the language (indexing, field access, pointer
dereferences and channel receives).
Instead of adding another map to Result, we return a *Pointer and
populate it during analysis. This does mean that a Config cannot be
reused for multiple analyses, as it now holds analysis-specific state.
That is, however, not a big problem as reusing one Config had little
use.
Since the new API can do everything the old could, it deprecates
AddQuery and AddIndirectQuery.

The export data formats (text and binary) emitted by gc in Go 1.7 did
not record the package that "owns" each blank field, even though blank
is an unexported identifier. Before, gcimporter would assume the
package of the export data file owns blank fields within it, even
blank fields reexported from another package. As a result, identical
types would become nonidentical during reexporting.
For bug compatibility with gc, gcimporter now treats blank fields as
if they all belong to the same dummy package, avoiding spurious "can't
assign A to B" errors in tools based on go/types.

The BuilderModeFlag function does not work with flag packages (such as
Google's) that define their own FlagSet. This change exposes a type
that satisifies flag.Value insted of a function. That type
is *BuilderMode; there's no need for a separate wrapper type.

This CL makes little observable difference to the behavior but paves the
way for streaming 'referrers' and (later) 'implements' queries which
scan the entire workspace, but print each result as soon as it is found.
The go/loader package now exposes a hook, AfterTypeCheck, that lets
clients inspect each package as soon as it is type-checked, and also
modify it, for instance to release unneeded data structures.
A 'referrers' query applied to an exported object must scan the entire
workspace. It uses this hook so to gather uses of the query object in
streaming fashion. However, for now, it still accumulates the results
and prints them all at the end, though I propose to change that in a
follow-up.
Code details:
- The referrers logic had a 2-iteration loop to load first the query
package and then if necessary the enlarged program. The second
iteration has now been unrolled and split into globalReferrers.
- Queries for package names (whether in a package declaration or
a qualified identifier) have been split off into packageReferrers.
It now loads all direct importers of the query package,
which catches some references that were missing before.
(It used to inspect only the forward dependencies of the query
package.)
Also:
- Referrers.Pos (the position of query identifier) was removed from the
JSON output. It's a nuisance to compute now, and it's already
absent from the plain output.
(In a follow-up, I plan to simplify the information content of the
JSON output exactly what is currently printed in the plain output.)

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.

This change prevents test code to slip into package gcimporter15 and
fixes a weird situation that the test passes but the package doesn't
exist.
For example, we can see the situation with Go 1.6 like the follwoing:
go build

./gcimporter_test16.go:45: undefined: testPath
go test

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
the documentation of RepoRoot.Root struct field:
// Root is the import path corresponding to the root of the
// repository.
Root string
