Previously, the unified frontend implemented unsafe.Sizeof, etc that involved derived types by constructing a normal OSIZEOF, etc expression, including fully instantiating their argument. (When unsafe.Sizeof is applied to a non-generic type, types2 handles constant folding it.) This worked, but involves unnecessary work, since all we really need to track is the argument type (and the field selections, for unsafe.Offsetof). Further, the argument expression could generate temporary variables, which would then go unused after typecheck replaced the OSIZEOF expression with an OLITERAL. This results in compiler failures after CL 523315, which made later passes stricter about expecting the frontend to not construct unused temporaries. Fixes #62515.

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.
