Keith Randall 93e3696b5d cmd/compile: avoid past-the-end pointer when zeroing
When we optimize append(s, make([]T, n)...), we have to be careful
not to pass &s[0] + len(s)*sizeof(T) as the argument to memclr, as that
pointer might be past-the-end. This can only happen if n is zero, so
just special-case n==0 in the generated code.

Fixes #67255

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:

../bin/go test cmd/internal/testdir

To run just tests from specified files in this directory, execute:

../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.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.
