The tools section TODO can be removed since the tools section looks
complete by now.
All TODOs in the minor changes to the library section have been done,
so the top-level TODO is resolved. Delete it.
The currently highlighted entries under Core library section look
good. It's worth reviewing this further based on feedback from Go
1.16 pre-releases, so keep the TODO but make it non-user-visible
to unblock Go 1.16 Beta 1.
For #40700.

This change adds an additional line explaining the ordering of the
supported metrics list. It's also necessary to ensure "Supported
metrics" is displayed by godoc as a proper header.
This modification does mean the description test, that ensures
descriptions line up with documentation, needs to change slightly
so it it doesn't read this new line as documentation. Make this
new line the line the test uses to decide when to begin.

When the -linkshared build mode is in effect, the Go command passes
the "-linkshared" command line option to the compiler so as to insure
special handling for things like builtin functions (which may appear

this behavior to the assembler, since the assembler may also wind up

go test sets the working directory to that of the package being tested,
so opening one of the package source files can be done in a simpler way.
This also allows the test to run in more environments, for example when
GOROOT_FINAL¹ is set.
Also remove the testenv.HasSrc-like check for Go source. The doc.go
file is a part of the package being built and tested, so it's expected
to be available. If it's important for this test to handle when a test
binary is built with go test -c and executed elsewhere without package
source files, something more than testenv.HasSrc would be needed.

Issue #41600 fixed the issue when a second request canceled a connection
while the first request was still in roundTrip.
This uncovered a second issue where a request was being canceled (in
roundtrip) but the connection was put back into the idle pool for a
subsequent request.
The fix is the similar except its now in readLoop instead of roundTrip.
A persistent connection is only added back if it successfully removed
the cancel function; otherwise we know the roundTrip has started
cancelRequest.

This is a port of CL 275517 from the dev.typeparams branch, to fix the
positioning of error messages for invalid const init expressions that
are inherited.
Differences from CL 275517:
+ The inherited flag is added to the constDecl intermediate
representation.
+ The errpos override is made a positioner, the internal interface
used by go/types to capture error position and span. For const decls
errpos is just set to a singular point, but using positioner is
correct and causes span start and end positions to also be
overridden.
+ Test cases are updated to assert on just 'overflows', as the go/types
error message is, for example, "cannot use 255 + iota (untyped int
constant 256) as byte value in constant declaration (overflows)".
This is more verbose than the compiler's "constant 256 overflows
byte", but changing that is out of scope.
Fixes#42991

According to [1], this function returns NULL when it errors, rather than
INVALID_HANDLE_VALUE, which other Win32 functions return. This was
pointed out in CL 273446 for the x/sys package, and this patch here
cleans it up for the syscall package and updates the vendored x/sys
package using the usual `go get/go mod vendor` dance. The function is
currently in use by crypto/x509/root_windows.go, which calls
CertOpenStore(CERT_STORE_PROV_MEMORY), which I assume can fail under OOM
or other weird conditions. Quick reversing indicates that [1] is
correct, as there's a `xor eax, eax` in the error paths of the function
just before jumping to the epilogue.

Sub provides a convenient way to refer to a subdirectory
automatically in future operations, like Unix's chdir(2).
The CL also includes updates to fstest to check Sub implementations.
As part of updating fstest, I changed the meaning of TestFS's
expected list to introduce a special case: if you list no expected files,
that means the FS must be empty. In general it's OK not to list all
the expected files, but if you list none, that's almost certainly a
mistake - if your FS were broken and empty, you wouldn't find out.
Making no expected files mean "must be empty" makes the mistake
less likely - if your file system ever worked, then your test will keep
it working.
That change found a testing bug: embedtest was making exactly
that mistake.
Fixes#42322.

An address of offset(SP) may point to the callee args area, and
may be used to move things into/out of the args/results. If an
address like that is spilled and picked up by the GC, it may hold
an arg/result live in the callee, which may not actually be live
(e.g. a result not initialized at function entry). Make sure
they are rematerializeable, so they are always short-lived and
never picked up by the GC.
This CL changes 386, PPC64, and Wasm. On AMD64 we already have
the rule (line 2159). On other architectures, we already have
similar rules like
(OffPtr [off] ptr:(SP)) => (MOVDaddr [int32(off)] ptr)
to avoid this problem. (Probably me in the past had run into
this...)

pinning bad values to throwing, as these values shouldn't be possible to
pass (except as below).
timeSleep may overflow timer.nextwhen. This would previously have been
pinned by resetForSleep, now we fix it manually.
runOneTimer may overflow timer.when when adding timer.period. Detect
this and pin to maxWhen.
addtimer is now too strict to allow TestOverflowRuntimeTimer to test an
overflowed timer. Such a timer should not be possible; to help guard
against accidental inclusion siftup / siftdown will check timers as it
goes. This has been replaced with tests for period and sleep overflows.

timer when == 0, in the context of timer0When and timerModifiedEarliest,
is a sentinel value meaning there are no timers on the heap.
TestCheckRuntimeTimerOverflow reaching into the runtime to set a timer
to when = 0 when it is otherwise not possible breaks this invariant.
After golang.org/cl/258303, we will no longer detect and run this timer,
thus blocking any other timers lower on the heap from running. This
manifests as random timers failing to fire in other tests.
The need to set this overflowed timer to when = 0 is gone with the old
timer proc implementation, so we can simply remove it.
