052d402985 runtime: clear mspan.largeType more carefully in the case of arenas
The pointer stored in mspan.largeType is an invalid pointer when
the span is an arena. We need to make sure that pointer isn't seen
by the garbage collector, as it might barf on it. Make sure we
zero the pointer using a uintptr write so the old value isn't picked
up by the write barrier.

The mspan.largeType field itself is in a NotInHeap struct, so a heap
scan won't find it. The only way we find it is when writing it, or
when reading it and putting it in a GC-reachable location. I think we
might need to audit the runtime to make sure these pointers aren't
being passed in places where the GC might (non-conservatively) scan a
stack frame it lives in. (It might be ok, many such places are either
systemstack or nosplit.)

ba7c4e47b3 os: limit temp file randomness to uint32
CL 516860 accidentally changed the randomness
used in TempFile from 32 to 64 bits on 64-bit platforms,
meaning from 10 to 20 decimal bytes.
This is enough to cause problems in a few tests
because it makes temporary directory names just
a little bit longer.

Limit back down to 32 bits of randomness, which is fine,
and add a test to avoid repeating the mistake.

Fixes #64605.

e1cba47ee0 go/parser: fix panic in object resolution for invalid type parameter list
This change restores the original logic in parseParameterList to what
it was before CL 538858 (which caused the issue), not in exact wording
but in identical semantic meaning, and thus restores this function to
a state that we know was working fine.

However, the change keeps the improved error reporting introduced by
CL 538858. To keep the code changes somewhat minimal as we are close
to RC1, the improved error handling exists twice for now even though
it could be factored out.

Fixes #64534.

6cdf2ccae8 cmd/go: relax version regexp from CL 547998
In CL 547998 I relaxed cmd/go's parsing of version lines to allow it

I added a check for a version 3-tuple following the word "version".
However, it appears that some releases of GCC use only a 2-tuple instead.

788a227759 cmd/compile: fix SCCP propagation into jump tables
We can't delete all the outgoing edges and then add one back in, because
then we've lost the argument of any phi at the target. Instead, move
the important target to the front of the list and delete the rest.

This normally isn't a problem, because there is never normally a phi
at the target of a jump table. But this isn't quite true when in race
build mode, because there is a phi of the result of a bunch of raceread
calls.

The reason this happens is that each case is written like this (where e
is the runtime.eface we're switching on):

if e.type == $type.int32 {
   m = raceread(e.data, m1)
}
m2 = phi(m1, m)
if e.type == $type.int32 {
   .. do case ..
   goto blah
}

so that if e.type is not $type.int32, it falls through to the default
case. This default case will have a memory phi for all the (jumped around
and not actually called) raceread calls.

If we instead did it like

if e.type == $type.int32 {
  raceread(e.data)
  .. do case ..
  goto blah
}

That would paper over this bug, as it is the only way to construct
a jump table whose target is a block with a phi in it. (Yet.)

But we'll fix the underlying bug in this CL. Maybe we can do the
rewrite mentioned above later.  (It is an optimization for -race mode,
which isn't particularly important.)

Fixes #64606

dca2ef2361 runtime: put runtime.fastrand back temporarily
Callers should be using math/rand/v2.Uint64 instead,
but there are lots of linkname references to runtime.fastrand
in public code. If we break it all now, that will require people
to use //go:build tags to use rand/v2.Uint64 with Go 1.22
and keep using the linkname for earlier versions.
Instead, leave the linkname working and then we can remove
it in Go 1.24, at which point everyone should be able to use
math/rand/v2.Uint64 unconditionally.

e1c0349a7c internal/profile: fully decode proto even if there are no samples
This is a partial revert of CL 483137.

CL 483137 started checking errors in postDecode, which is good. Now we
can catch more malformed pprof protos. However this made
TestEmptyProfile fail, so an early return was added when the profile was
"empty" (no samples).

Unfortunately, this was problematic. Profiles with no samples can still
be valid, but skipping postDecode meant that the resulting Profile was
missing values from the string table. In particular, net/http/pprof
needs to parse empty profiles in order to pass through the sample and
period types to a final output proto. CL 483137 broke this behavior.

internal/profile.Parse is only used in two places: in cmd/compile to
parse PGO pprof profiles, and in net/http/pprof to parse before/after
pprof profiles for delta profiles. In both cases, the input is never
literally empty (0 bytes). Even a pprof proto with no samples still
contains some header fields, such as sample and period type. Upstream
github.com/google/pprof/profile even has an explicit error on 0 byte
input, so `go tool pprof` will not support such an input.

Thus TestEmptyProfile was misleading; this profile doesn't need to
support empty input at all.

Resolve this by removing TestEmptyProfile and replacing it with an
explicit error on empty input, as upstream
github.com/google/pprof/profile has. For non-empty input, always run
postDecode to ensure the string table is processed.

TestConvertCPUProfileEmpty is reverted back to assert the values from
before CL 483137. Note that in this case "Empty" means no samples, not a
0 byte input.

Continue to allow empty files for PGO in order to minimize the chance of
last minute breakage if some users have empty files.

Fixes #64566.

b11d19e03b cmd/asm: print absolute PC for all patterns "off(PC)" in testEndToEnd
Before this CL, testEndToEnd only turns the relative PC to absolute PC
when pattern "off(PC)" is the suffix of an instruction. But there are
some instructions like:

  ADR 10(PC), R10

it's also acceptable for the assembler while the pattern "off(PC)" is
not a suffix, which makes the test fail.

This CL fixes this issue by searching the pattern in the whole string
instead of only in the suffix.

98fd8f5768 runtime: rename GODEBUG=profileruntimelocks to runtimecontentionstacks
profileruntimelocks is new in CL 544195, but the name is deceptive. Even
with profileruntimelocks=0, runtime-internal locks are still profiled.
The actual difference is that call stacks are not collected. Instead all
contention is reported at runtime._LostContendedLock.

Rename this setting to runtimecontentionstacks to make its name more
aligned with its behavior.

In addition, for this release the default is profileruntimelocks=0,
meaning that users are fairly likely to encounter
runtime._LostContendedLock. Rename it to
runtime._LostContendedRuntimeLock in an attempt to make it more
intuitive that these are runtime locks, not locks in application code.

For #57071.

6e33a6376e cmd/go: use local go cache for cover_statements script test
Use a test-local directory for GOCACHE in "cover_statements" script
test, as a workaround for issue 64014.

For the portion of this test that verifies that caching works
correctly, the cache should theoretically always behave
reliably/deterministically, however if other tests are concurrently
accessing the cache while this test is running, it can lead to cache
lookup failures, which manifest as a flaky failure. To avoid such
flakes, use a separate isolated GOCACHE for this test.

For #64014.
