For code like the following (where x escapes): x := []int{1} We're currently generating a nil check. The line above is really 3 operations: t := new([1]int) t[0] = 1 x := t[:] We remove the nil check for t[0] = 1, but not for t[:]. Our current nil check removal rule is too strict about the possible memory arguments of the nil check. Unlike zeroing or storing to the result of runtime.newobject, the nilness of runtime.newobject is always false, even after other stores have happened in the meantime.

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
go run run.go
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgo
and other Go tool chains.
