c2079deb24 cmd/cgo/internal/testsanitizers: check for go build and cgo in fuzzer and msan tests
Make sure the platform we are running the tests on can compile programs
and has cgo support in order to run the fuzzer and msan tests. This is the
same approach used by the asan tests, which share the same requirements.

Fixes #64626

0ac1e3b245 go/types, types2: flip message contents for reverse type inference errors
Add a new flag 'reverse' to control the formatting of type inference
error messages.

This change only impacts error messages.

Fixes #60747.

2643a59172 go/types, types2: better error message for cases of reverse type inference
Introduce a new type "target" to pass around target types together
with a suitable description (typically a variable name) for a better
error message.

As a side effect, using a specific type (target), rather than just Type
avoids accidental confusion with other types.

Use the target type description for a better error message in some
cases.

The error message can be further improved by flipping the order of
the sentence (for another CL to keep this one small and simple).

Also, and unrelated to this fix, remove the first argument to errorf
in infer.go: the argument is always "type" (there's only one call).

For #60747.

a839ec1e73 cmd/go/internal/modload: classify "invalid pseudo-version" errors in Query
If we encounter an unclassified error in modload.Query, it takes
precedence even if the package is found in some other module.
(That is intentional, so that if a package exists in both a parent
and a nested module the outcome is deterministic, and does not shift
if a temporary error causes one of the modules to be unavailable.)

A pseudo-version is formed from a base version and a commit hash.
Each version tag is specific to the module in a particular directory
of the repo (often the root directory), whereas the commit hash is
the same for all subdirectories. When we go to check a particular
subdirectory for the requested package, we may find that that version
is not valid for that combination of <subdirectory, commit hash>,
but we should keep looking to see whether it is valid for a module
in some other subdirectory.

Fixes #47650.

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.

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
to recognize clang versions with vendor prefixes. To prevent false-positives,
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.

Updates #64423.
Fixes #64619.

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.

c71eedf90a cmd/go: accept clang versions with vendor prefixes
To better diagnose bugs like this one in the future, I think
we should also refuse to use a C compiler if we can't identify
a sensible version for it. I did not do that in this CL because
I want it to be small and low-risk for possible backporting.

Fixes #64423.

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.
