Dan Scales 006d4e6278 cmd/compile: fix case where we didn't delay transformAssign in varDecl
We delay all transformations on generic functions, and only do them on
instantiated functions, for several reasons, of which one is that
otherwise the compiler won't understand the relationship between
constrained type parameters. In an instantiation with shape arguments,
the underlying relationship between the type arguments are clear and
don't lead to compiler errors.

This issue is because I missed delaying assignment transformations for
variable declarations. So, we were trying to transform an assignment,
and the compiler doesn't understand the relationship between the T and U
type parameters.

The fix is to delay assignment transformations for variable declarations
of generic functions, just as we do already for normal assignment
statements.

A work-around for this issue would be to just separate the assignment
from the variable declaration in the generic function (for this case of
an assignment involving both of the constrained type parameters).

Fixes #50147

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 run run.go

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

../bin/go run run.go -- 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.
