ca2cb8d7a7 cmd/internal/testdir: remove temp files
Function stdlibImportcfgFile creates a temporary directory and a file in
it, which are never deleted.

The easiest to fix this (without creating the file unnecessarily, or
creating it multiple times) is to add a global tmpDir and use it in
stdlibImportcfgFile.

1e2114349d cmd/compile/internal/syntax: handle parentheses around constraints consistently
Generally, the parser strips (i.e., does not record in the syntax tree)
unnecessary parentheses. Specifically, given a type parameter list of
the form

        [P (C),]

it records it as

        [P C]

and then no comma is required when printing. However it did only strip
one level of parentheses, and

        [P ((C)),]

made it through, causing a panic when printing. Somewhat related,
the printer stripped parentheses around constraints as well.

This CL implements a more consistent behavior:

1) The parser strips all parentheses around constraints. For testing
   purposes, a local flag (keep_parens) can be set to retain the
   parentheses.

2) The printer code now correctly intruces a comma if parentheses
   are present (e.g., when testing with keep_parens). This case does
   not occur in normal operation.

3) The printer does not strip parentheses around constraints since
   the parser does it already.

For #69206.

c3f16307b3 go/printer: do not treat comments inside a ast.Decl as godoc
This change makes sure that we do not format comments
as doc comments inside of a declaration and makes the
go doc formatter idempotent:

Previously:

	// test comment
	//go:directive2
	// test comment
func main() {
}

was formatted to:

// test comment
//go:directive2
// test comment
func main() {
}

after another formatting, it got formatted with doc rules into:

// test comment
// test comment
//
//go:directive2
func main() {
}

With this change it gets directly to the correct form (last one).

f22d731976 go/build/constraint: add parsing limits
Limit the size of build constraints that we will parse. This prevents a
number of stack exhaustions that can be hit when parsing overly complex
constraints. The imposed limits are unlikely to ever be hit in real
world usage.

Fixes #69141
Fixes CVE-2024-34158

08c84420bc encoding/gob: cover missed cases when checking ignore depth
This change makes sure that we are properly checking the ignored field
recursion depth in decIgnoreOpFor consistently. This prevents stack
exhaustion when attempting to decode a message that contains an
extremely deeply nested struct which is ignored.

Thanks to Md Sakib Anwar of The Ohio State University (anwar.40@osu.edu)
for reporting this issue.

d102c2ed01 os: don't fail TestGetwdDeepWithPWDSet if TMPDIR has a symlink
When testing with PWD set, it's possible for the stat of PWD to fail
with ENAMETOOLONG, and for syscall.Getwd to fail for the same reason.
If PWD contains symlinks, the fallback code won't know about them.
If Getwd returns the same result as PWD with resolved symlinks,
the test should not fail.

9ba8ac253e cmd/link/internal/ld: rm os.Getwd from dwarf_test
Calls to os.Getwd were needed to set the cwd for go build to an absolute
path. Since CL 401340 os/exec takes care of setting PWD to a
filepath.Abs(cmd.Dir), so it looks like an absolute path is not
really required.

de0aafa3c7 vendor/golang.org/x/tools: update to v0.24.1-0.20240904143311-70f56264139c
Among other things, this should fix a regression in printf
whereby materialized aliases caused "any" and "interface{}"
in printf signatures not to be recognized as identical.

It also updates ureader.go used by vendored x/tools during
some tests, including cmd/internal/moddeps.TestAllDependencies.
This test uses golang.org/x/tools/cmd/bundle which uses x/reader.

Fixes #68796

004686b6e5 crypto/internal/nistec: Avo port of p256_asm_amd64.s
This implementation utilizes the same registers found in the reference
implementation, aiming to produce a minimal semantic diff between the
Avo-generated output and the original hand-written assembly.

To verify the Avo implementation, the reference and Avo-generated
assembly files are fed to `go tool asm`, capturing the debug output into
corresponding temp files. The debug output contains supplementary
metadata (line numbers, instruction offsets, and source file references)
that must be removed in order to obtain a semantic diff of the two
files. This is accomplished via a small utility script written in awk.

The reference assembly file does not specify a frame size for a number
of the defined assembly functions. Avo automatically infers the frame
size when generating the TEXT directive, leading to a diff on those
lines.

Commands used to verify Avo output:

6ee8c07c3c crypto/aes: Avo port of gcm_amd64.s
This implementation utilizes the same registers found in the reference
implementation, aiming to produce a minimal semantic diff between the
Avo-generated output and the original hand-written assembly.

To verify the Avo implementation, the reference and Avo-generated
assembly files are fed to `go tool asm`, capturing the debug output into
corresponding temp files. The debug output contains supplementary
metadata (line numbers, instruction offsets, and source file references)
that must be removed in order to obtain a semantic diff of the two
files. This is accomplished via a small utility script written in awk.

The reference assembly file does not specify a frame size for some of
the defined assembly functions. Avo automatically infers the frame size
when generating TEXT directives, leading to a diff on those lines. Some
metadata not included in the reference assembly has also been added,
which leads to a diff in the lines where that parameter symbol is
referenced.

Commands used to verify Avo output:

GOROOT=$(go env GOROOT)
ASM_PATH="src/crypto/aes/gcm_amd64.s"
REFERENCE="54fe0fd43fcf8609666c16ae6d15ed92873b1564"

go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \
  <(git cat-file -p "$REFERENCE:$ASM_PATH") \
  > /tmp/reference.s

go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \
  "$ASM_PATH" \
  > /tmp/avo.s

normalize(){
  awk '{
    $1=$2=$3="";
    print substr($0,4)
  }'
}
