CL 181857 broke the translation of certain C types using cmd/cgo -godefs
because it stores each typedef, array and qualified type with their
parent type name in the translation cache.
Fix this by only considering the parent type for typedefs of anonymous
structs which is the only case where types might become ambiguous.

Use a uniform function (named “quiesce”) to wait for possible signals
in a way that gives the kernel many opportunities to deliver them.
Simplify channel usage and concurrency in stress tests.
Use (*testing.T).Deadline instead of parsing the deadline in TestMain.
In TestStop, sleep forever in a loop if we expect the test to die from
a signal. That should reduce the flakiness of TestNohup, since
TestStop will no longer spuriously pass when run as a subprocess of
TestNohup.
Since independent signals should not interfere, run the different
signals in TestStop in parallel when testing in short mode.
Since TestNohup runs TestStop as a subprocess, and TestStop needs to
wait many times for signals to quiesce, run its test subprocesses
concurrently and in short mode — reducing the latency of that test by
more than a factor of 2.
The above two changes reduce the running time of TestNohup on my
workstation to ~345ms, making it possible to run much larger counts of
the test in the same amount of wall time. If the test remains flaky
after this CL, we can spend all or part of that latency improvement on
a longer settle time.

have followed suit since CL 96455. Most people building Go will have
a Go toolchain in their PATH and will not need to specify a different
toolchain.
This CL removes the GOROOT_BOOTSTRAP mention from the contribution guide
(it was there for Windows only, but it's not required anymore). The guide
is meant to be light and clear for beginners and is not supposed to be
a reference, so there's not need to keep mentioning GOROOT_BOOTSTRAP.

Retrying CL 222782, with a fix that will hopefully stop the random crashing.
The issue with the previous CL is that it does pointer arithmetic
in a way that may briefly generate an out-of-bounds pointer. If an
interrupt happens to occur in that state, the referenced object may
be collected incorrectly.
Suppose there was code that did s[x+c]. The previous CL had a rule
to the effect of ptr + (x + c) -> c + (ptr + x). But ptr+x is not
guaranteed to point to the same object as ptr. In contrast,
ptr+(x+c) is guaranteed to point to the same object as ptr, because
we would have already checked that x+c is in bounds.
For example, strconv.trim used to have this code:
MOVZX -0x1(BX)(DX*1), BP
CMPL $0x30, AL
After CL 222782, it had this code:
LEAL 0(BX)(DX*1), BP
CMPB $0x30, -0x1(BP)
An interrupt between those last two instructions could see BP pointing
outside the backing store of the slice involved.
It's really hard to actually demonstrate a bug. First, you need to
have an interrupt occur at exactly the right time. Then, there must
be no other pointers to the object in question. Since the interrupted
frame will be scanned conservatively, there can't even be a dead
pointer in another register or on the stack. (In the example above,
a bug can't happen because BX still holds the original pointer.)
Then, the object in question needs to be collected (or at least
scanned?) before the interrupted code continues.
This CL needs to handle load combining somewhat differently than CL 222782
because of the new restriction on arithmetic. That's the only real
difference (other than removing the bad rules) from that old CL.
This bug is also present in the amd64 rewrite rules, and we haven't
seen any crashing as a result. I will fix up that code similarly to
this one in a separate CL.

gentraceback generates PCs which are usually following the CALL

functions processing the output can unconditionally decrement the PC.
runtime_expandInlineFrames does this unconditional decrement when
looking up the function. However, the fake stack frame generated for
overflow records fails to meet the contract, and decrementing the PC
results in a PC in the previous function. If that function contains
inlined call, runtime_expandInlineFrames will not short-circuit and will
panic trying to look up a PC that doesn't exist.
Note that the added test does not fail at HEAD. It will only fail (with
a panic) if the function preceeding lostProfileEvent contains inlined
function calls. At the moment (on linux/amd64), that is
runtime/pprof.addMaxRSS, which does not.

This makes all modern public keys in the standard library implement a
common interface (below) that can be used by applications for better
type safety and allows for checking that public (and private keys via
Public()) are equivalent.
interface {
Equal(crypto.PublicKey) bool
}
Equality for ECDSA keys is complicated, we take a strict interpretation
that works for all secure applications (the ones not using the
unfortunate non-constant time CurveParams implementation) and fails
closed otherwise.
Tests in separate files to make them x_tests and avoid an import loop
with crypto/x509.
Re-landing of CL 223754. Dropped the test that was assuming named curves
are not implemented by CurveParams, because it's not true for all
curves, and anyway is not a property we need to test. There is still a
test to check that different curves make keys not Equal.

As we now have -go115newobj flag, it is better to use go115 in
the object file as well. And it already diverges from the go114
"new" object file format.

This should restore deterministic order of dynexp, and fix

On Solaris, in the runtime it defines the external name of
runtime.etext as _etext (runtime/os3_solaris.go:13). In CL 224939
we changed to put external names in the ELF symbol table more
consistently. In this case it will contain _etext but not
runtime.etext.
To be conservative, this CL defines both runtime.etext and _text
in the linker.
