go/internal/gcimporter: remove support for type parameters subscripts

Now that the compiler no longer includes subscripts in its export data,
we can remove support for parsing them in the gcimporter.

Make this change, as well as add support for exporting the new names to
iexport.go (tests fail if these changes are made in separate CLs). This
proved a bit tricky to debug, so along the way add some hooks for easier
tracing of import/export.

Fix a bug in iimport.go where rparams were being shadowed, and fix the
export tests to actually compare methods.

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.


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.

JS/CSS Formatting

This repository uses prettier to format JS and CSS files.

The version of prettier used is 1.18.2.

It is encouraged that all JS and CSS code be run through this before submitting a change. However, it is not a strict requirement enforced by CI.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/tools/(your subdir):” in the subject line, so it is easy to find.
