When gentraceback starts on a system stack in sigprof, it is
configured to jump to the user stack when it reaches the end of the
system stack. Currently this updates the current frame's FP, but not
its SP. This is okay on non-LR machines (x86) because frame.sp is only
used to find defers, which the bottom-most frame of the user stack
will never have.
However, on LR machines, we use frame.sp to find the saved LR. We then
use to resolve the function of the next frame, which is used to
resolved the size of the next frame. Since we're not updating frame.sp
on a stack jump, we read the saved LR from the system stack instead of
the user stack and wind up resolving the wrong function and hence the
wrong frame size for the next frame.
This has had remarkably few ill effects (though the resulting profiles
must be wrong). We noticed it because of a bad interaction with stack
barriers. Specifically, once we get the next frame size wrong, we also
get the location of its LR wrong. If we happen to get a stack slot
that contains a stale stack barrier LR (for a stack barrier we already
hit) and hasn't been overwritten with something else as we re-grew the
stack, gentraceback will fail with a "found next stack barrier at ..."
error, pointing at the slot that it thinks is an LR, but isn't.

Instead, introduce the ResponseWriter.Result method, returning an

for Go 1.7 in CL 20047. Result().Header now contains the correct

Currently it's possible for user code to exploit the high scheduler
priority of the GC worker in conjunction with the runnext optimization
to elevate a user goroutine to high priority so it will always run
even if there are other runnable goroutines.
For example, if a goroutine is in a tight allocation loop, the
following can happen:
1. Goroutine 1 allocates, triggering a GC.
2. G 1 attempts an assist, but fails and blocks.
3. The scheduler runs the GC worker, since it is high priority.
Note that this also starts a new scheduler quantum.
4. The GC worker does enough work to satisfy the assist.
5. The GC worker readies G 1, putting it in runnext.
6. GC finishes and the scheduler runs G 1 from runnext, giving it
the rest of the GC worker's quantum.
7. Go to 1.
Even if there are other goroutines on the run queue, they never get a
chance to run in the above sequence. This requires a confluence of
circumstances that make it unlikely, though not impossible, that it
would happen in "real" code. In the test added by this commit, we
force this confluence by setting GOMAXPROCS to 1 and GOGC to 1 so it's
easy for the test to repeated trigger GC and wake from a blocked
assist.
We fix this by making GC always put user goroutines at the end of the
run queue, instead of in runnext. This makes it so user code can't
piggy-back on the GC's high priority to make a user goroutine act like
it has high priority. The only other situation where GC wakes user
goroutines is waking all blocked assists at the end, but this uses the
global run queue and hence doesn't have this problem.

In https://golang.org/3210, Transport errors occurring before
receiving response headers were wrapped in another error type to
indicate to the retry logic elsewhere that the request might be
re-tryable. But a check for err == io.EOF was missed, which then became
false once io.EOF was wrapped in the beforeRespHeaderError type.
The beforeRespHeaderError was too fragile. Remove it. I tried to fix
it in an earlier version of this CL and just broke different things
instead.
Also remove the "markBroken" method. It's redundant and confusing.
Also, rename the checkTransportResend method to shouldRetryRequest and
make it return a bool instead of an error. This also helps readability.
Now the code recognizes the two main reasons we'd want to retry a
request: because we never wrote the request in the first place (so:
count the number of bytes we've written), or because the server hung
up on us before we received response headers for an idempotent request.
As an added bonus, this could make POST requests safely re-tryable
since we know we haven't written anything yet. But it's too late in Go
1.7 to enable that, so we'll do that later (filed #15723).
This also adds a new internal (package http) test, since testing this
blackbox at higher levels in transport_test wasn't possible.

The fact that crypto/ecdsa.Verify didn't reject negative inputs was a
mistake on my part: I had unsigned numbers on the brain. However, it
doesn't generally cause problems. (ModInverse results in zero, which
results in x being zero, which is rejected.)
The amd64 P-256 code will crash when given a large, negative input.
This fixes both crypto/ecdsa to reject these values and also the P-256
code to ignore the sign of inputs.

it caused static destructors to run twice. At least on glibc

Issue #15613 points out that the darwin builders have been getting
regular failures in which a process that should exit with a SIGPIPE
signal is instead exiting with exit status 2. The code calls
runtime.raise. On most systems runtime.raise is the equivalent of
pthread_kill(gettid(), sig); that is, it kills the thread with the
signal, which should ensure that the program does not keep going. On
darwin, however, runtime.raise is actually kill(getpid(), sig); that is,
it sends a signal to the entire process. If the process decides to
deliver the signal to a different thread, then it is possible that in
some cases the thread that calls raise is able to execute the next
system call before the signal is actually delivered. That would cause
the observed error.
I have not been able to recreate the problem myself, so I don't know
whether this actually fixes it. But, optimistically:

Uses reversed post order to cut number of passes, running
it from first def to last use ("last use" for paramout and

backedge is the source of the back edge)
Includes a cutover from old algorithm to new to avoid paying
large constant factor for small programs. This keeps normal
builds running at about the same time, while not running
over-long on large machine-generated inputs.
Add "phase" flags for ssa/build -- ssa/build/stats prints
number of blocks, values (before and after linking references
and inserting phis, so expansion can be measured), and their
product; the product governs the cutover, where a good value
seems to be somewhere between 1 and 5 million.

never consult the object itself (so it wouldn't observe uninitialized
memory even if it found a pointer to a noscan object), and the heap
bitmap was pre-initialized to noscan.
However, now we explicitly initialize the heap bitmap for noscan
objects when we allocate them. While the GC will still never consult
the contents of a noscan object, it does need to see the initialized
heap bitmap. Hence, we need to execute a publication barrier to make
the bitmap visible before user code can expose a pointer to the newly
allocated object even for noscan objects.

In future releases of OpenBSD, the sigreturn syscall will no longer
exist. As such, stop using sigreturn on openbsd/386 and just return
from the signal trampoline (as we already do for openbsd/amd64 and
openbsd/arm).

This is addressing feedback given on golang.org/cl/23052;
we do it in a separate CL to separate the functional from
the rename change.
ONAME was not used in the export data, but it's the natural node op
where we used OPACK instead. Renamed.
Furthermore, OPACK and ONONAME nodes are replaced by the type checker
with ONAME nodes, so OPACK nodes cannot occur when exporting type-checked
code. Removed a special-case for OPACK nodes since they don't appear.

The pprof tools properly cleans up all files it creates, but forgets

The //extern comments are incorrect and cause undefined symbol
errorswhen building cgo code with -compiler=gccgo. The code is already
designed to use weak references, and that support relies on the cgo
check functions being treated as local functions.

Summary: Go's HTTP/1.x server closes the request body once writes are
flushed. Go's HTTP/2 server supports concurrent read & write.
Added a TODO to make the HTTP/1.x server also support concurrent
read+write. But for now, document it.

The importer uses a global (shared) package map across multiple imports
to determine if a package was imported before. That package map is usually
indexed by package (import) path ('id' in this code). However, the binary
importer was using the incoming (possibly unclean) path.
Fixes#15517.

The -systemdll and -xsys flags generate broken code in some situations
(see issue for details). Fix all that.
This CL only fixes bugs in existing code, but I have more changes comming:
golang.org/x/sys/windows is not the only package that uses mksyscall_windows.go.
golang.org/x/exp/shiny and github.com/derekparker/delve do too. I also have
few personal packages that use mksyscall_windows.go. None of those packages
are aware of new -xsys flag. I would like to change mksyscall_windows.go, so
external packages do not need to use -xsys flag. I would love to get rid of
-xsys flag altogether, but I don't see how it is possible. So I will, probably,
replace -xsys with a flag that means opposite to -xsys, and use new flag
everywhere in standard libraries. Flag name suggestions are welcome.
-systemdll flag makes users code more "secure". I would like to make -systemdll
behaviour a default for all mksyscall_windows.go users. We use that already in
standard library. If we think "secure" is important, we should encourage it in
all users code. If mksyscall_windows.go user insist on using old code, provide
-use_old_loaddll (need good name here) flag for that. So -systemdll flag will
be replaced with -use_old_loaddll.
