Alan Donovan 0dcaae1610 go.tools/go/loader: permit Create* methods to specify the ad-hoc package's path
CL 49530047 made the (over-)simplifying assumption that the
Path of an ad-hoc (Created) package should default to its
Name, i.e. package declaration.

With this change, the Name is still always computed from the
package declaration (by go/types) but the Path may be
specified by the loader.Config.  If "", the value of the Name
is used, which is not globally unique.

Was:		Now:

Though call.Graph was cute, the original naming was a mistake:
'call' is too useful a var name to waste on a package.

Peter Collingbourne a0cc29953e go.tools/go/types: introduce Func.Scope()
The goal is to allow clients to distinguish function-local objects
from package-local objects and identify the specific function by
examining its scope. For example, a compiler may need to mangle
object names according to the outer function name.

The issue is addressed with the change in conversions.go.

- use *Basic with names byte/rune instead of uint8/int32 for better output
- minor cleanups

Peter Collingbourne 893253274d go.tools/go/gccgoimporter: importer for gccgo export data
This can import all of the standard library, and has been tested
by using gotype to type check libgo with gccgo's export data (this
would be nice to automate, but I can't see a good way to do it,
not least because system-specific source files cause errors which
I needed to identify manually).

It includes a builtin export locator. Unfortunately I can't see a
more reliable way to locate the builtin export files than to parse
the output of 'gccgo -###'.

Robert Griesemer 822669c658 go.tools/importer: fix field package for anonymous fields
Anonymous field names are emitted as "" in the export data
since the actual name can be reconstructed easily from the
field's type name. But "" names are not exported names and
thus the respective qualified name emits complete package
information even if the actual field name is exported. Fix
the package upon import.

Robert Griesemer df08273253 go.tools/gcimporter: use imported package info for anonymous fields
The package of a struct field is independent of the type of the
struct field - the old code was technically not correct. That said,
it does not seem possible (or very difficult) to create a test case
because for exported anonymous fields that field package doesn't matter
(it's not needed for name identity), and non-exported anonymous fields
cannot be accessed from an imported package.

Robert Griesemer 30645c4bc6 go.tools/go/importer: fine-tuning of export format, test against std lib
(TBR adonovan)

- provide version string rather than version number (more flexible)
- match naming of tag constants with documentation (forth-coming)
- more formats for constant values (1-byte booleans, short 64bit
  values, support for floating point numbers +123p+45)
- more regular format for signatures: always print with type tag;
  this permits (future) sharing of identical signatures and possibly
  large export data size reduction
- test export and import of all type-checked std library packages
- compare import of all std library packages against corresponding
  import of gc-generated export data and verify that the packages
  match 100% (except for floating point values which are exact when
  coming from go/types, and possibly inexact when coming from gc)

On average, export data generated by the importer is ~28% of the size
of the gc-generated export data for corresponding packages of the std
library:

By using a simple (graph-based) serialization algorithm
and binary encoding, a significantly more compact export
data format is achieved than what the current compilers
use. Furthermore, the exporter and importer are completely
symmetric algorithms that are compact, and much easier to

Alan Donovan 036b7d3489 go.tools/types: skip "imported but not used" check if IgnoreFuncBodies.
Obviously in that mode, we can't correctly diagnose such
errors, so we shouldn't attempt it (and emit false positives).

Robert Griesemer 14cf5b0a28 go.tools/go/types: fun with Hilbert: a const arithmetic test
This test generates a program that declares the constant
elements of an n*n Hilbert matrix, its inverse, and the
constant elements of the explicit product of the two.
The product should be the identity matrix; that check is
also expressed as a constant expression. Type-checking
verifies that the product is indeed the identity matrix
by asserting the result of the identity check (using the
assert built-in which is available for type-check tests).

The test is run for n = 5. Other values can be tested via
the -H flag, say: go test -run=Hilbert -H=100

The generated program can be written to a file for testing
the constant arithmetic of a compiler: go test -out=test.go

Because of the mathematically precise constant arithmetic
of go/types, this test should always succeed and is only
limited by the size of the matrix. It does run successfully
from n = 0 to values larger than 100.

The Hilbert matrix is famous for being ill-conditioned and
thus exposes arithmetic imprecision very quickly. The gc
compiler only produces a correct result for n = 0 (trivially),
and n = 1 at the moment.
