Daniel Martí fd752d5ede cmd/vendor: update to golang.org/x/tools@3ef68632
Mainly to pull in the bug fix in the structtag pass, where filenames
could sometimes be wrong. The bug wasn't present in 1.11, so it was a
regression and needs fixing before 1.12 is out.

Fixes #29130.

Filippo Valsorda 35f4ec152b crypto/x509: ignore harmless edge case in TestSystemRoots
The no-cgo validation hack lets in certificates from the root store that
are not marked as roots themselves, but are signed by a root; the cgo
path correctly excludes them. When TestSystemRoots compares cgo and
no-cgo results it tries to ignore them by ignoring certificates which
pass validation, but expired certificates were failing validation.

Letting through expired certs is harmless anyway because we will refuse
to build chains to them.

Fixes #29497

Filippo Valsorda 303a596d8c crypto/x509: ignore 5 phantom 1024-bit roots in TestSystemRoots
On macOS 10.11, but not 10.10 and 10.12, the C API returns 5 old root
CAs which are not in SystemRootCertificates.keychain (but seem to be in
X509Anchors and maybe SystemCACertificates.keychain, along with many
others that the C API does not return). They all are moribund 1024-bit
roots which are now gone from the Apple store.

Since we can't seem to find a way to make the no-cgo code see them,
ignore them rather than skipping the test.

David Chase 28fb8c6987 cmd/compile: modify swt.go to skip repeated walks of switch
The compiler appears to contain several squirrelly corner
cases where nodes are double walked, some where new nodes
are created from walked parts.  Rather than trust that we
had searched hard enough for the last one, change
exprSwitch.walk() to return immediately if it has already
been walked.  This appears to be the only case where
double-walking a node is actually harmful.

Fixes #29562.

Dmitri Shuralyov 4c3b4dfd79 CONTRIBUTORS: first round of automated updates for Go 1.12
These updates have been automatically generated using a modified
version of the updateac command with the following changes:

-	code to automatically update the AUTHORS file has been removed,
	since we're not updating that file automatically after Go 1.11
	(see CL 128877)
-	CLA checking code has been removed, since it was primarily needed
	for updating the AUTHORS file
-	instead of executing the misc/sortac binary, its code was embedded
	into the updateac command itself

The modified updateac command will be added to x/build repository soon,
and the misc/sortac command can be removed afterwards.

Austin Clements 95a6f112c6 runtime: work around "P has cached GC work" failures
We still don't understand what's causing there to be remaining GC work
when we enter mark termination, but in order to move forward on this
issue, this CL implements a work-around for the problem.

If debugCachedWork is false, this CL does a second check for remaining
GC work as soon as it stops the world for mark termination. If it
finds any work, it starts the world again and re-enters concurrent
mark. This will increase STW time by a small amount proportional to
GOMAXPROCS, but fixes a serious correctness issue.

This works-around #27993.

Alessandro Arzilli 374546d800 cmd/go: respect gcflags, ldflags in 'go test'
Fixes bug introduced by https://golang.org/cl/129059 where
gcflags='all=...' and ldflags='all=...' would not be applied to some
packages built by 'go test'.

LoadImport used to set gcflags/ldflags for the Package objects it
created, in https://golang.org/cl/129059 this code was factored out to
setToolFlags. The codepath of `go build` was updated to call
setToolFlags appropriatley, but the codepath of `go test -c` wasn't,
resulting in gcflags/ldflags being applied inconsistently when building
tests.

This commit changes TestPackagesFor to call setToolFlags on the package
objects it creates.

Austin Clements 8e6396115e runtime: don't spin in checkPut if non-preemptible
Currently it's possible for the runtime to deadlock if checkPut is
called in a non-preemptible context. In this case, checkPut may spin,
so it won't leave the non-preemptible context, but the thread running
gcMarkDone needs to preempt all of the goroutines before it can
release the checkPut spin loops.

Fix this by returning from checkPut if it's called under any of the
conditions that would prevent gcMarkDone from preempting it. In this
case, it leaves a note behind that this happened; if the runtime does
later detect left-over work it can at least indicate that it was
unable to catch it in the act.

For #27993.
Updates #29385 (may fix it).

so despiteallobjections I have updated the copyright year.

Keith Randall 14bdcc76fd cmd/compile: fix racewalk{enter,exit} removal
We can't remove race instrumentation unless there are no calls,
not just no static calls. Closure and interface calls also count.

The problem in issue 29329 is that there was a racefuncenter, an
InterCall, and a racefuncexit.  The racefuncenter was removed, then
the InterCall was rewritten to a StaticCall. That prevented the
racefuncexit from being removed. That caused an imbalance in
racefuncenter/racefuncexit calls, which made the race detector barf.

Bug introduced at CL 121235

Fixes #29329

Keith Randall 69c2c56453 cmd/compile,runtime: redo mid-stack inlining tracebacks
Work involved in getting a stack trace is divided between
runtime.Callers and runtime.CallersFrames.

Before this CL, runtime.Callers returns a pc per runtime frame.
runtime.CallersFrames is responsible for expanding a runtime frame
into potentially multiple user frames.

After this CL, runtime.Callers returns a pc per user frame.
runtime.CallersFrames just maps those to user frame info.

Entries in the result of runtime.Callers are now pcs
of the calls (or of the inline marks), not of the instruction
just after the call.

Fixes #28640
Update #26320
