"aliased" is the function responsible for detecting whether we can
turn "a, b = x, y" into just "a = x; b = y", or we need to pre-compute
y and save it in a temporary variable because it might depend on a.
It currently has two issues:
1. It suboptimally treats assignments to blank as writes to heap
memory. Users generally won't write "_, b = x, y" directly, but it
comes up a lot in generated code within the compiler.
This CL changes it to ignore blank assignments.
2. When deciding whether the assigned variable might be referenced by
pointers, it mistakenly checks Class() and Name.Addrtaken() on "n"
(the *value* expression being assigned) rather than "a" (the
destination expression).
It doesn't appear to result in correctness issues (i.e.,
incorrectly reporting no aliasing when there is potential aliasing),
due to all the (overly conservative) rewrite passes before code
reaches here. But it generates unnecessary code and could have
correctness issues if we improve those other passes to be more
aggressive.
This CL fixes the misuse of "n" for "a" by renaming the variables
to "r" and "l", respectively, to make their meaning clearer.
Improving these two cases shaves 4.6kB of text from cmd/go, and 93kB
from k8s.io/kubernetes/cmd/kubelet:
text data bss dec hex filename
9732136 290072 231552 10253760 9c75c0 go.before
9727542 290072 231552 10249166 9c63ce go.after

97884549 1007051 301344 99192944 5e99070 kubelet.after
While here, this CL also collapses "memwrite" and "varwrite" into a
single variable. Logically, they're detecting the same thing: are we
assigning to a memory location that a pointer might alias. There's no
need for two variables.

We generally don't care about errors in resolving a repo if the result
we're looking for is already in the module cache. Moreover, we can
avoid some expense in initializing the repo if all of the methods we
plan to call on it hit in the cache — especially when using
GOPROXY=direct.
This also incidentally fixes a possible (but rare) bug in Download:
we had forgotten to reset the downloaded file in case the Zip method

go test runs a limited number of vet checks by default.
In the standard library, we run more, both to get additional checking
for the standard library and to get experience with whether to enable
any others by default.
One that experience has shown us should not be enabled by default
is go vet -unreachable. When you are testing, it is common to want to
put an early return or a panic into code to bypass a section of code.
That often causes unreachable code. It's incredibly frustrating if the
result is an "unreachable code" error that keeps your test from completing.

For special runtime C symbols (e.g. crosscall2), they used to be
exported dynamically, and we had a special case for pclntab to
not include those symbols (otherwise, when the dynamic linker
dedup them, the pclntab entries end up pointing out of the

Add note about using per-use seeds.

"Collision-resistant" has a precise cryptographic meaning that is
incompatible with "not cryptographically secure".
All that is really meant by it here here is "it's a good hash function",
which should be established already.
Also delete:
> The hash value of a given byte sequence is consistent within a

This was added for its final clause in response to #37040,
but "The hash value of a given byte sequence" is by design not a
concept in this package. Only "... of a given seed and byte sequence".
And seeds cannot be shared between processes, so again by design
you can't even set up the appropriate first half of the sentence
to say the second half.

{{"hello" |
printf}}
Now that unclosed actions can span multiple lines,
track and report the start of the action when reporting errors.
Also clean up a few "unexpected <error message>" to be just "<error message>".
Fixes#29770.

Like we did for sync, let the runtime give net random numbers,
to avoid forcing an import of math/rand for DNS.

We have a Bool() accessor for the value in boolean nodes, that we use
elsewhere for n.Val().U.(bool), use it here too. Noticed while reading
the code.

When a module author retracts a version, the go command should act as
if it doesn't exist unless it's specifically requested.
When converting a revision to a version, we should ignore tags for
retracted versions. For example, if the tag v1.0.0 is retracted, and
branch B points to the same revision, we should convert B to a
pseudo-version, not v1.0.0. Similarly, if B points to a commit after
v1.0.0, we should not use v1.0.0 as the base; we can use an earlier
non-retracted tag or no base.
