callbackUpdateSystemStack contains a fast path to exit early without
update if SP is already within the g0.stack bounds.
This is not safe, as a subsequent call may have new stack bounds that
only partially overlap the old stack bounds. In this case it is possible
to see an SP that is in the old stack bounds, but very close to the
bottom of the bounds due to the partial overlap. In that case we're very
likely to "run out" of space on the system stack.
We only need to do this on extra Ms, as normal Ms have precise bounds
defined when we allocated the stack.
TSAN annotations are added to x_cgo_getstackbounds because bounds is a
pointer into the Go stack. The stack can be reused when an old thread
exits and a new thread starts, but TSAN can't see the synchronization
there. This isn't a new case, but we are now calling more often.

As mentioned in CL 584598, linkname is a mechanism that, when
abused, can break API integrity and even safety of Go programs.
CL 584598 is a first step to restrict the use of linknames, by
implementing a blocklist. This CL takes a step further, tightening
up the restriction by allowing linkname references ("pull") only
when the definition side explicitly opts into it, by having a
linkname on the definition (possibly to itself). This way, it is at
least clear on the definition side that the symbol, despite being
unexported, is accessed outside of the package. Unexported symbols
without linkname can now be actually private. This is similar to
the symbol visibility rule used by gccgo for years (which defines
unexported non-linknamed symbols as C static symbols).
As there can be pull-only linknames in the wild that may be broken
by this change, we currently only enforce this rule for symbols
defined in the standard library. Push linknames are added in the
standard library to allow things build.
Linkname references to external (non-Go) symbols are still allowed,
as their visibility is controlled by the C symbol visibility rules
and enforced by the C (static or dynamic) linker.
Assembly symbols are treated similar to linknamed symbols.
This is controlled by -checklinkname linker flag, currently not
enabled by default. A follow-up CL will enable it by default.

Linknaming an instantiated generic symbol isn't particularly
useful: it doesn't guarantee the instantiation exists, and the
instantiated symbol name may be subject to change. Checked with a
large code corpus, currently there is no occurrance of linkname
to an instantiated generic symbol (or symbol with a bracket in its
name). This also suggests that it is not very useful. Linkname is
already an unsafe mechanism. We don't need to allow it to do more
unsafe things without justification.

CL 581215 changed 'throw' so that instead of print(s) it called
a more complicated function, printpanicval, that statically
appeared to have convTstring in its call graph, even though this
isn't dynamically reachable when called with a string argument.
However, this caused the link-time static callgraph test to point
out that throw (which is called in nowritebarrierrec contexts
such as markgc) reaches a write barrier.
The solution is to inline and specialize the printpanicval
function for strings; it reduces to printindented.
Thanks to mpratt for pointing out that the reachability
check is on the fully lowered code, and is thus sensitive
to optimizations such as inlining.

The Requirements structure, which represents the root level requirements
of the module graph also has a 'direct' field which contains the set of
direct dependencies of a module.
Before this change, in workspace mode, the direct field was not set on
the Requirements structure. This change sets direct in the two places
it's needed: when initializing Requirements from the workspace's mod
files and when updating Requirements based on imports.
When initializing Requirements from the workspace's mod files, this
change will use the 'indirect' comments in those mod files to record the
set of direct modules passed to the Requirements.
There is a loop in updateRequirements where we consider the imports of
the packages we loaded from the main module to make sure that all those
imported packages' modules are required. The loop also updates direct
for each of those modules (which have at least one package directly
imported by the main modules). Before this change, in the workspace
case we continued early from the loop and didn't proceed to the code
where direct is computed. This change fixes that.

Currently, the SEH symbol is defined as an aux symbol of the
function symbol, without adding to ctxt.Data. Each function has
its own SEH symbol. As there are a lot of duplications of the
SEH symbol contents, currently a Go object file may contain many
copies of identical SEH symbols. They are deduplicated at link
time. But it does make the linker do redundant work, and make it
hard to reason about the SEH symbol writing in the object file
writer, and its resolution in the linker. In fact, in the object
file writer, the same SEH symbol may be added to the ctxt.defs
multiple times (as it is the aux of multiple function symbols),
which is not expected.
In fact, "aux symbol" is just a mechanism to associate auxiliary
data to another symbol. The auxiliary data symbol itself can be an
ordinary data symbol, even a content-addressable symbol. Define
the SEH symbol as a conntent-addressable symbol and add it to
ctxt.Data. This way there is only one definition of each unique
SEH symbol, which can be the aux of many functions.
While here, add a check to ensure that we add a symbol at most
once to the defs list.

This also fixes a bug where an implicit 100-continue could be

This change drops tracking of whether we've written a

was used to determine whether we should consume the remaining
request body in chunkWriter.writeHeader, but the discard-the-body

(If the body is not consumed, we set closeAfterReply, and we
don't consume the remaining body when closeAfterReply is set.
If the body is consumed, then we may attempt to discard the

Trying to write a test for the corner cases in the old async timer chan
implementation may have been a mistake, especially since this isn't
going to be the default timer chan implementation anymore.
But let's try one more time to fix the test.
I reproduced the remaining builder failures on my Mac laptop
by overloading the CPU in one window and then running 48 instances
of the flaky test in loops using 'stress' in another window.
It turns out that, contrary to my understanding of async timers
and therefore contrary to what the test expected, it is technically
possible for
t := time.NewTicker(1)
t.Reset(1000*time.Hour)
<-t.C
<-t.C
to observe two time values on t.C, as opposed to blocking forever.
We always expect the first time value, since the ticker goes off
immediately (after 1ns) and sends that value into the channel buffer.
To get the second value, the ticker has to be in the process of
going off (which it is doing constantly anyway), and the timer
goroutine has to be about to call sendTime and then get rescheduled.
Then t.Reset and the first <-t.C have to happen.
Then the timer goroutine gets rescheduled and can run sendTime's
non-blocking send on t.C, which finds an empty buffer and writes
a value.
This is unlikely, of course, but it definitely happens. This program
always panics in just a second or two on my laptop:
package main
import (
"os"
"time"
)
func main() {
os.Setenv("GODEBUG", "asynctimerchan=1")

Because I did not understand this nuance, the test did not expect it.
This CL rewrites the test to expect that possibility. I can no longer
make the test fail under 'stress' on my laptop.
For #66322.

This patch changes the Go linker to "clean" (reset to Unix epoch) the
timestamps on object files copied to the tmpdir that is presented to
the external linker or archive tool. The intent is to improve build
reproducibility on Darwin, where later versions of xcode seem to want
to incorporate object file timestamps into the hash used for the final
build ID (which precludes the possibility of having reproducible Go
builds). Credit for this idea goes to Cherry (see
https://github.com/golang/go/issues/64947#issuecomment-1887667189).
Updates #64947.

If unpadded content was passed, in some occassions content was omitted,
because the division result was floored. Ceiling it makes sure all
content is always read.
