go work sync resets the state in the modload package before each
iteration where it updates the workspace modules' go.mod files. But
before this change it wasn't resetting the global state in the modfetch
package. This is necessary because the modfetch package keeps track of
the sums that will be written to go.sum. Further, the fetch caches
will update information about which modules are used when fetching
packages, and so those caches need to be cleared between each workspace
module.

This is a stop gap solution to avoid panics due to stack overflow

it prevents a panic during compilation and reports a (possibly not

If the programs are correct in the first place, manually providing

If we have more than 2 arguments, we may have arguments with named and
unnamed types. If that is the case, permutate params and args such that
the arguments with named types are first in the list. This doesn't affect
type inference if all types are taken as is. But when we have inexact
unification enabled (as is the case for function type inference), when
a named type is unified with an unnamed type, unification proceeds with
the underlying type of the named type because otherwise unification would
fail right away. This leads to an asymmetry in type inference: in cases
where arguments of named and unnamed types are passed to parameters with
identical type, different types (named vs underlying) may be inferred
depending on the order of the arguments.
By ensuring that named types are seen first, order dependence is avoided
and unification succeeds where it can.
This CL implements the respectice code but keeps it disabled for now,
pending decision whether we want to address this issue in the first

Until now, CTI (constraint type inference) was run before
FTI (function type inference). This lead to situations
where CTI infered a type that is missing necessary methods
even though a function argument of correct type was given.
This can happen when constraint type inference produces a
inferred type that is the structural type of multiple types,
which then is an underlying type, possibly without methods.
This CL removes the initial CTI step; it is only applied
after FTI with type arguments is run, and again after FTI
with untyped arguments is run.
Various comments are adjusted to reflect the new reality.

I made the default be that, where there are differences between types2
and -G=0 error messages, we want errorcheck tests to pass types2.
Typically, we can get errorcheck to pass on types2 and -G=0 if they give
the same number of error messages on the same lines, just different
wording. If they give a different number of error messages, then I made
types2 pass. I added an exception list for -G=0 to cover those cases
where -G=0 and types give different numbers of error messages.
Because types2 does not run if there are syntax errors, for several
tests, I had to split the tests into two parts in order to get all the
indicated errors to be reported in types2 (bug228.go, bug388.go,
issue11610.go, issue14520.go)
I tried to preserve the GCCGO labeling correctly (but may have gotten
some wrong). When types2 now matches where a GCCGO error previously
occurred, I transformed GCCGO_ERROR -> ERROR. When types2 no longer
reports an error in a certain place, I transformed ERROR -> GCCGO_ERROR.
When types2 reports an error in a new place, I used GC_ERROR.
The remaining entries in types2Failures are things that I think we
probably still need to fix - either actually missing errors in types2,
or cases where types2 gives worse errors than -G=0.

Finally figured out how to deal with the interaction between generics
and inlining. The problem has been: what to do if you inline a function
that uses a new instantiated type that hasn't been seen in the current
package? This might mean that you need to do another round of
function/method instantiatiations after inlining, which might lead to
more inlining, etc. (which is what we currently do, but it's not clear
when you can stop the inlining/instantiation loop).
We had thought that one solution was to export instantiated types (even
if not marked as exportable) if they are referenced in exported
inlineable functions. But that was quite complex and required changing
the export format. But I realized that we really only need to make sure
the relevant dictionaries and shape instantiations for the instantiated
types are exported, not the instantiated type itself and its wrappers.
The instantiated type is naturally created as needed, and the wrappers
are generated automatically while writing out run-time type (making use
of the exported dictionaries and shape instantiations).
So, we just have to make sure that those dictionaries and shape
instantiations are exported, and then they will be available without any
extra round of instantiations after inlining. We now do this in
crawler.go. This is especially needed when the instantiated type is only
put in an interface, so relevant dictionaries/shape instantiations are
not directly referenced and therefore exported, but are still needed for
the itab.
This fix avoids the phase ordering problem where we might have to keep
creating new type instantiations and instantiated methods after each
round of inlining we do.
Removed the extra round of instantiation/inlining that were added in the
previous fix. The existing tests
test/typeparam{geninline.go,structinit.go} already test this situation
of inlining a function referencing a new instantiated type.
Added the original example from issue 50121 as test (has 5 packages),
since it found a problem with this code that the current simpler test
for 50121 did not find.

CL 352870 added extra phase for instantiation after inlining, to take
care of the new fully-instantiated types. However, when fetching inlined
body of these types's methods, we need to allow OADDR operations on
untyped expressions, the same as what main inlining phase does.
The problem does not show up, until CL 371554, which made the compiler
do not re-typecheck while importing, thus leaving a OXDOT node to be
marked as address taken when it's not safe to do that.
Fixes#50437

Since a SECURITY.md file is present in the main Go repository,
GitHub already shows a "Report a security vulnerability" link
in the issue template list. Remove the duplicate custom link.

The release notes explicitly refer to sections updated
for generics in the spec but then point to the old spec
which is very confusing for beta users.

Rat maintains the invariant that x.b.neg is always false,
but Rat.Denom was writing x.b.neg = false itself too.
That makes Rat.Denom a writing operation, when it should
be a read-only operation. That in turn makes it unsafe to
use from multiple goroutines, which is highly unexpected.
Make it read-only and therefore race-free again.
Fixes#50473.
