toolstash-check

Overview ¶

Toolstash-check automates running toolstash -cmp against a CL.

Usage:

toolstash-check [-all] [commit]

Toolstash-check automates the following workflow for compiler regression testing a CL:

1. Clone the $GOROOT Git repo into a new temporary directory.

2. Checks out the specified commit's parent.

3. Runs make.bash and toolstash save. (It sets GOROOT so that toolstash saves into the temporary directory.)

4. Checks out the specified commit itself.

5. Runs "go install std cmd".

6. Runs "go build -a -toolexec='toolstash -cmp' std cmd".

If no commit ID is specified, toolstash-check defaults to HEAD.

If -all is specified, toolstash-check instead runs golang.org/x/tools/cmd/toolstash/buildall for the final step.
