Matthew Dempsky 00715d089d cmd/compile/internal/walk: copy SSA-able variables 
order.go ensures expressions that are passed to the runtime by address
are in fact addressable. However, in the case of local variables, if the
variable hasn't already been marked as addrtaken, then taking its
address here will effectively prevent the variable from being converted
to SSA form.

Instead, it's better to just copy the variable into a new temporary,
which we can pass by address instead. This ensures the original variable
can still be converted to SSA form.

Fixes #63332.

README.md

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.
