      cmd/go: adjust heuristics for skipping +incompatible versions · 817afe83
      Bryan C. Mills authored 
      We know of at least one module (github.com/stripe/stripe-go) that has
a run of +incompatible versions, followed by a run of versions with
go.mod files, followed by another run of +incompatible versions.

We want the heuristics for showing +incompatible versions to reflect
the authors' current intent, and it seems clear that the current
intent of the authors of that module is for users of the unversioned
import path to still be on +incompatible versions.

To respect that intent, we need to keep checking for +incompatible
versions even after we have seen a lower major version with an
explicit go.mod file.

However, we still don't want to download every single version of the
module to check it. A given major version should have a consistent,
canonical import path, so the path (as inferred by the presence or
absence of a go.mod file) should be the same for every release across
that major version.

To avoid unnecessary overhead — and to allow module authors to correct
accidental changes to a major version's import path — we check only
the most recent release of each major version. If a release
accidentally changes the import path in either direction (by deleting
or adding a go.mod file), it can be corrected by issuing a single
subsequent release of that major version to restore the correct path.

I manually verified that, with this change,
github.com/stripe/stripe-go@latest reverts to v68.7.0+incompatible
as it was in Go 1.13.
The other regression tests for #34165 continue to pass.

Updates #34165

      cmd/compile: give every really deep type a unique name · 2248fc63
      Keith Randall authored 
      This avoids the security problem in #29312 where two very deep, but
distinct, types are given the same name. They both make it to the
linker which chooses one, and the use of the other is now type unsafe.

Instead, give every very deep type its own name. This errs on the
other side, in that very deep types that should be convertible to each
other might now not be. But at least that's not a security hole.

Update #29312.

      runtime: use FP offsets for pipe/pipe2 on freebsd/arm64 and linux/arm64 · 4b1b18d1
      Joel Sing authored 
      This is more readable and less error-prone than using RSP offsets.

Suggested during review of CL 212765.
