packages (more)
This fixes two problems missed in CL 164877.
First, p.Internal.BuildInfo is now part of the cache key. This is
important since p.Internal.BuildInfo causes the build action to
synthesize a new source file, which affects the output.
Second, recompileForTest is always called for test
packages. Previously, it was only called when there were internal test
sources, so the fix in CL 164877 did not apply to packages that only
had external tests.
Fixes #30937

The current wasm write barrier implementation incorrectly implements
the "deletion" part of the barrier. It correctly greys the new value
of the pointer, but rather than also greying the old value of the
pointer, it greys the object containing the slot (which, since the old
value was just overwritten, is not going to contain the old value).
This can lead to unmarked, reachable objects.
Often, this is masked by other marking activity, but one specific
sequence that can lead to an unmarked object because of this bug is:
1. Initially, GC is off, object A is reachable from just one pointer
in the heap.
2. GC starts and scans the stack of goroutine G.
3. G copies the pointer to A on to its stack and overwrites the
pointer to A in the heap. (Now A is reachable only from G's stack.)
4. GC finishes while A is still reachable from G's stack.
With a functioning deletion barrier, step 3 causes A to be greyed.
Without a functioning deletion barrier, nothing causes A to be greyed,
so A will be freed even though it's still reachable from G's stack.
This CL fixes the wasm write barrier.
Fixes #30873.

Getdirentries is implemented with the __getdirentries64 function
in libSystem.dylib. That function works, but it's on Apple's
can't-be-used-in-an-app-store-application list.
Implement Getdirentries using the underlying fdopendir/readdir_r/closedir.
The simulation isn't faithful, and could be slow, but it should handle
common cases.
Don't use Getdirentries in the stdlib, use fdopendir/readdir_r/closedir
instead (via (*os.File).readdirnames).

passing by value
CL 135377 introduces pass strings and slices to convT2{E,I} by value.
Before that CL, all types, except interface will be allocated temporary
address. The CL changes the logic that only constant and type which
needs address (determine by convFuncName) will be allocated.
It fails to cover the case where type is static composite literal.
Adding condition to check that case fixes the issue.
Also, static composite literal node implies constant type, so consttype
checking can be removed.

lookupIP
In CL 120215 the cgo resolver was changed to have different logic based
on the network being queried. However, the singleflight cache key wasn't
updated to also include the network. This way it was possible for
concurrent queries to return the result for the wrong network.
This CL changes the key to include both network and host, fixing the
problem.

versioned binaries
This change is a re-apply of the reverted CL 140863 with changes to
address issue #30821. Specifically, path.Split continues to be used
to split the '/'-separated import path, rather than filepath.Split.
Document the algorithm for how the default executable name is determined
in DefaultExecName.
Rename a variable returned from os.Stat from bs to fi for consistency.
CL 140863 factored out the logic to determine the default executable
name from the Package.load method into a DefaultExecName function,
and started using it in more places to avoid having to re-implement
the logic everywhere it's needed. Most previous callers already computed
the default executable name based on the import path. The load.Package
method, before CL 140863, was the exception, in that it used the p.Dir
value in GOPATH mode instead. There was a NOTE(rsc) comment that it
should be equivalent to use import path, but it was too late in Go 1.11
cycle to risk implementing that change.
This is part 1, a more conservative change for backporting to Go 1.12.2,
and it keeps the original behavior of splitting on p.Dir in GOPATH mode.
Part 2 will address the NOTE(rsc) comment and modify behavior in
Package.load to always use DefaultExecName which splits the import path
rather than directory. It is intended to be included in Go 1.13.

inline gen
When generating DWARF inline info records, the post-SSA code looks
through the original "pre-inline" dcl list for the function so as to
handle situations where formal params are promoted or optimized away.
This code was not properly handling the case where an output parameter
was promoted to the heap -- in this case the param node is converted
in place from class PPARAMOUT to class PAUTOHEAP. This caused
inconsistencies later on, since the variable entry in the abstract
subprogram DIE wound up as a local and not an output parameter.

While many other call sites have been moved to using the proper
higher-level system loading, these areas were left out. This prevents
DLL directory injection attacks. This includes both the runtime load
calls (using LoadLibrary prior) and the implicitly linked ones via
cgo_import_dynamic, which we move to our LoadLibraryEx. The goal is to
only loosely load kernel32.dll and strictly load all others.
Meanwhile we make sure that we never fallback to insecure loading on
older or unpatched systems.
This is CVE-2019-9634.

versioned binaries
`go build` has chosen the last element of the package import path
as the default output name when -o option is given. That caused
the output of a package build when the module root is the major
version component such as 'v2'.
A similar issue involving `go install` was fixed in
https://golang.org/cl/128900. This CL refactors the logic added
with the change and makes it available as
internal/load.DefaultExecName.
This CL makes 'go test' to choose the right default test binary

Trying to call a method on a nil interface is a panic in Go. For
example:
var stringer fmt.Stringer
println(stringer.String()) // nil pointer dereference
In https://golang.org/cl/143097 we started recovering panics encountered
during function and method calls. However, we didn't handle this case,
as text/template panics before evalCall is ever run.
In particular, reflect's MethodByName will panic if the receiver is of
interface kind and nil:
panic: reflect: Method on nil interface value
Simply add a check for that edge case, and have Template.Execute return
a helpful error. Note that Execute shouldn't just error if the interface
contains a typed nil, since we're able to find a method to call in that
case.
Finally, add regression tests for both the nil and typed nil interface
cases.
Fixes #30464.

Currently, runtime.KeepAlive applied on a stack object doesn't
actually keeps the stack object alive, and the heap object
referenced from it could be collected. This is because the
address of the stack object is rematerializeable, and we just
ignored KeepAlive on rematerializeable values. This CL fixes it.

Instead of trying to guess type of constants in the AST,
which is hard, use the "var cgo%d Type = Constant"
so that typechecking is left to the Go compiler.
The previous code could still fail in some cases
for constants imported from other modules
or defined in other, non-cgo files.

Make sure the side effects inside short-circuited operations (&& and ||)
happen correctly.
Before this CL, we attached the side effects to the node itself using
exprInPlace. That caused other side effects in sibling expressions
to get reordered with respect to the short circuit side effect.
Instead, rewrite a && b like:
r := a
if r {
r = b
}
That code we can keep correctly ordered with respect to other
side-effects extracted from part of a big expression.
exprInPlace seems generally unsafe. But this was the only case where
exprInPlace is called not at the top level of an expression, so I
don't think the other uses can actually trigger an issue (there can't
be a sibling expression). TODO: maybe those cases don't need "in
place", and we can retire that function generally.
This CL needed a small tweak to the SSA generation of OIF so that the
short circuit optimization still triggers. The short circuit optimization
looks for triangle but not diamonds, so don't bother allocating a block
if it will be empty.
Go 1 benchmarks are in the noise.

packages
The -coverpkg lets users specify a list of packages that should have
coverage instrumentation. This may include packages not transitively
imported by tests. For each tested package, the synthetic main package
imports all covered packages so they can be registered with
testing.RegisterCover. This makes it possible for a main package to
import another main package.
When we compile a package with p.Internal.BuildInfo set (set on main
packages by Package.load in module mode), we set
runtime/debug.modinfo. Multiple main packages may be passed to the
linker because of the above scenario, so this causes duplicate symbol
errors.
This change copies p.Internal.BuildInfo to the synthetic main package
instead of the internal test package. Additionally, it forces main
packages imported by the synthetic test main package to be recompiled
for testing. Recompiled packages won't have p.Internal.BuildInfo set.

tracebackdefers, but it seems to me that tracebackdefers doesn't
include the func value itself, which could be a stack allocated
closure. Scan it explicitly.
Alternatively, we can change tracebackdefers to include the func
value, which in turn needs to change the type of stkframe.

Revert CL 137055, which changed Clean("\\somepath\dir\") to return
"\\somepath\dir" on Windows. It's not entirely clear this is correct,
as this path is really "\\server\share\", and as such the trailing
slash may be the path on that share, much like "C:\". In any case, the
change broke existing code, so roll it back for now and rethink for 1.13.
