go/analysis/passes/buildtag: split out of vet

buildtag checker:
- This checker has been modified from the version in vet to handle Go
  and non-Go files differently, to avoid having to re-read-and-parse
  Go files in the common case.
- The old cmd/vet driver would run this check on all the files in
  a directory whereas new drivers will run it only on the files
  selected for a particular configuration, so some of the checks
  (those in checkArguments) will never fire. But this is not a regression
  relative to 'go vet', because it too presents cmd/vet with only the
  files selected as part of the package.

analysistest:
- fix bug that processed a block of //-comments as one.
- treat "...// want..." within a //-comment as a want comment.
  This is required for adding expectations on lines that are already comments.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
