go/version.IsValid do not consider prerelease patch as valid version, but some prerelease patches actually do exist in history versions, such as go1.8.5rc5, go1.8.5rc4, go1.9.2rc2 .The version go1.9.2rc2 even could be found from https://go.dev/dl/?mode=json&include=all, and downloaded from https://dl.google.com/go/go1.9.2rc2.linux-amd64.tar.gz. It's unreasonable to treat an existing version as an invalid version, so it should be fixed.

The trace parser was using an otherwise-unused event argument to hold an
extra goroutine state argument for the GoStatus & GoStatusStack events.
This is needed because the execution tracer just records the "after" for
state transitions, but we want to have both the "before" and "after"
states available in the StateTransition info for the parsed event. When
GoStatusStack was added, the size of the argument array was increased to
still have room for the extra status. However, statuses are currently
only 1 byte, and the status argument is 8 bytes, so there is plenty of
room to pack the "before" and "after" statuses in a single argument. Do
that instead to avoid the need for an extra argument.

1) Factor out handling of receiver from Checker.funcType into
Checker.collectRecv. Analyze the receiver parameter "manually"
without resorting to calling Checker.collectParams.
The code is more straight-forward and error handling is simpler
because constructing the receiver type and variable is all handled
in one function.
2) Change Checker.collectParams to collect parameter names and
corresponding parameter variables, but do not declare them.
Instead return two equal-length slices of parameter names
and variables for later declaration.
3) Streamline Checker.funcType into a sequence of simple steps.
By declaring the receiver and parameters after type parameters,
there is no need for a temporary scope and scope squashing anymore.
4) Simplify Checker.unpackRecv some more: don't strip multiple
*'s from receiver type expression because we don't typecheck
that expression as a whole later (we don't use collectParams
for receiver types anymore). If we have a **T receiver, we
need to use *T (one * stripped) as receiver base type expression
so that we can report an error later.
5) Remove Checker.recvTParamMap and associated machinery as it is
not needed anymore.
6) Remove Scope.Squash/squash as it is not needed anymore.
7) Remove the explicit scope parameter from Checker.collectParams
as it is not needed anymore.
8) Minor adjustments to tests: in some cases, error positions have
shifted slightly (because we don't use Checker.collectParams to
typecheck receivers anymore), and in some cases duplicate errors
don't appear anymore (resolves TODOs).

Previously, the end position for a select statement clause body was
computed explicitly as the start of the next clause or the closing "}"
of the select statement, respectively.
Since syntax.EndPos computes the end position of a node, there's no
need to compute these positions "manually", we can simply use the
syntax.ExdPos for each clause. The positions are not exactly the
same as before but for the purpose of identifier visibility in
scopes there is no semantic change.

Move logic for type-specific variable type into typeCases function
which already does all the relevant work.
Add more detailed documentation to typeCases function.
Uncomment alernative typeCases function so that it is being type-
checked and kept up-to-date. Since it's not (yet) used, the code
will not appear in the binary.
Follow-up on CL 592555.

- Replace the various subst.XList methods with a generic function.
- Rename comparable function to comparableType to avoid shadowing
predeclared type comparable.
- Rename substFunc/Var to cloneFunc/Var which is more accurate.

Currently, we can only cache regular trace event buffers on each M. As
a result, calling unsafeTraceExpWriter will, in effect, always return
a new trace batch, with all of the overhead that entails.
This extends that cache to support buffers for experimental trace
data. This way, unsafeTraceExpWriter can return a partially used
buffer, which the caller can continue to extend. This gives the caller
control over when these buffers get flushed and reuses all of the
existing trace buffering mechanism.
This also has the consequence of simplifying the experimental batch
infrastructure a bit. Now, traceWriter needs to know the experiment ID
anyway, which means there's no need for a separate traceExpWriter
type.

From information we have available in the issue, this test was flaky
on OS X 10.10 but not newer. By now macOS 11 is the minimum required
version, and 1000 local runs of the test passed, so try to unskip as
the next step.
For #29225.

The abi.NoEscape function is introduced to replace all usages of
noescape wrapper in the standard library. However, the last usage in
reflect package is still present, because the inlining test failed if
abi.NoEscape were used. The reason is that reflect.noescape is treated
as a cheap call, while abi.NoEscape is not.
By treating abi.NoEscape a cheap call, the last usage of noescape in
reflect package can now be removed.

The typechecker is assuming that alias instances cannot be reached from
a named type. However, when type parameters on aliases are permited, it
can happen.
This CL changes the typechecker to propagate the correct named instance
