This lets us start taking advantage of featurs from Go 1.23, particularly tracking aliases in go/types and iterators. Note that we need to add code to properly handle or skip over the new *types.Alias type which go/types produces for Go type aliases. Also note that we actually turn this mode off entirely for now, due to the bug reported at https://go.dev/issue/70394. We don't yet remove our own alias tracking code yet due to the above. We hope to be able to remove it very soon.

# A fairly average Go build, importing some std libraries.
|
|
# We always build for a foreign GOOS.
|
|
# GOOS=windows, unless the host is also windows; then linux.
|
|
# GOARCH=arm, unless the host is also arm; then amd64.
|
|
# Windows and ARM are both interesting,
|
|
# and it helps with coverage as we mainly test on linux/amd64.
|
|
#
|
|
# We also ensure that intrinsics work as expected.
|
|
# The compiler replaces calls to some functions with intrinsics in its ssa stage,
|
|
# and it recognizes which functions via the package path and func name.
|
|
# If we obfuscate those package paths without adjusting the compiler,
|
|
# intrinsics aren't applied, causing performance loss or build errors.
|
|
# We use the math/bits package, as its Len64 intrinsic is present in both arm
|
|
# and arm64, and it is not part of the runtime nor its dependencies.

# As a last step, also test building for MacOS if we're not already on it.
|
|
# We already cover Windows and Linux above, and MacOS is the other major OS.
|
|
# The way it is implemented in the standard library, in particular with syscalls,
|
|
# is different enough that it sometimes causes special bugs.
