/ directory. The VersionHandling test will pick it up.
/
/ In the testdata/versions:
/
/ go build -o test_go1.$X_$Y.a test.go
/
/ with $X = Go version and $Y = export format version
/ (add 'b' or 'i' to distinguish between binary and
/ indexed format starting with 1.11 as long as both
/ formats are supported).
/
/ Make sure this source is extended such that it exercises
/ whatever export format change has taken place.
package test
/ Any release before and including Go 1.7 didn't encode
/ the package for a blank struct field.
