Keith Randall e283473ebb cmd/compile: avoid using destination pointer base type in memmove optimization The type of the source and destination of a memmove call isn't always accurate. It will always be a pointer (or an unsafe.Pointer), but the base type might not be accurate. This comes about because multiple copies of a pointer with different base types are coalesced into a single value. In the failing example, the IData selector of the input argument is a [32]byte in one branch of the type switch, and a []byte in the other branch. During the expand_calls pass both IDatas become just copies of the input register. Those copies are deduped and an arbitrary one wins (in this case, *[]byte is the unfortunate winner). Generally an op v can rely on v.Type during rewrite rules. But relying on v.Args[i].Type is discouraged.

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 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.
