The cmd/dist cgo_test enumerates a large number of platforms in
various special cases. Some combinations are suspiciously absent. This
CL completes the combinations.
I've confirmed using trybots that the newly-enabled tests pass on
android/* (this is not surprising because the gohostos is never
"android" anyway), windows/arm64, linux/ppc64 (no cgo), linux/loong64
(except for one test, filed #56623), linux/mips*, netbsd/arm (except
for one test, filed #56629), and netbsd/arm64. The windows/arm builder
is out to lunch, so I'm assuming that works. Since netbsd/arm and
arm64 mostly passed these tests, I've also enabled them on netbsd/386
and netbsd/amd64, where they seem to work fine as well.

The go1 benchmark suite does a lot of work at package init time, which
makes it take quite a while to run even if you're not running any of
the benchmarks, or if you're only running a subset of them. This leads
to an awkward workaround in dist test to compile but not run the
package, unlike roughly all other packages. It also reduces isolation
between benchmarks by affecting the starting heap size of all
benchmarks.
Fix this by initializing all data required by a benchmark when that
benchmark runs, and keeping it local so it gets freed by the GC and
doesn't leak between benchmarks. Now, none of the benchmarks depend on
global state.
Re-initializing the data on each benchmark run does add overhead to an
actual benchmark run, as each benchmark function is called several
times with different values of b.N. A full run of all benchmarks at
the default -benchtime=1s now takes ~10% longer; higher -benchtimes
would be less. It would be quite difficult to cache this data between
invocations of the same benchmark function without leaking between
different benchmarks and affecting GC overheads, as the testing
package doesn't provide any mechanism for this.
This reduces the time to run the binary with no benchmarks from 1.5
seconds to 10 ms, and also reduces the memory required to do this from
342 MiB to 17 MiB.
To make sure data was not leaking between different benchmarks, I ran
the benchmarks with -shuffle=on. The variance remained low: mostly
under 3%. A few benchmarks had higher variance, but in all cases it
was similar to the variance between this change.
This CL naturally changes the measured performance of several of the
benchmarks because it dramatically changes the heap size and hence GC
overheads. However, going forward the benchmarks should be much better
isolated.

Currently, the entry-point to this test is a Bash script that smoke

This CL rearranges things so a pure Go Go test smoke tests the FORTRAN
compiler and then runs a non-test FORTRAN-containing Go binary.
While we're here, we fix a discrepancy when the host is GOARCH=amd64,
but the target is GOARCH=386. Previously, we would pick the wrong
libgfortran path because we didn't account for the cross-compilation,
causing the link to fail. Except for some reason this was ignored and
the test nevertheless "passed". In the new test we're a little more
strict, so this build failure will cause the test to fail, so we add a
little logic to account for cross-compilation with the host toolchain.

The testasan test was added back in 2013 (CL 10126044), many years
before Go added ASAN support in 2021 (CL 298611). So, in fact,
testasan does not test Go ASAN support at all, as you might expect
(misc/cgo/testsanitizers does that). It's intended to test whether the
Go memory allocator works in a mixed C/Go binary where the C code is
compiled with ASAN. The test doesn't actually use ASAN in any way; it
just simulates where ASAN of 2013 put its shadow mappings. This made
sense to test at the time because Go was picky about where its heap
landed and ASAN happened to put its mappings exactly where Go wanted
to put its heap. These days, Go is totally flexible about its heap
placement, and I wouldn't be surprised if ASAN also works differently.
Given all of this, this test adds almost no value today. Drop it.

The flag is now removed from `go build` and `go test`.
It has been deprecated since Go 1.16, printing a warning message.
The idea was to fully delete it in Go 1.17, but that didn't happen.
First, delete the BuildI variable and its flag declarations,
as well as all the bits of docs that mentioned the flag.
Second, delete or simplify the code paths that used BuildI.
Third, adapt the tests to the removed flag.
Some of them are removed, like test_relative_import_dash_i.txt and
TestGoTestDashIDashOWritesBinary, as they centered around the flag.
The rest are modified to not cover or use the flag.
Finally, change cmd/dist to no longer use `go install -i`.
The purpose of the flag was that, when bootstrapping the toolchain,
all of its dependencies would also be installed as object files.
When removing the use of the -i flags, the checkNotStale call right
after building toolchain3 would fail as expected,
because runtime/internal/sys is now only up to date in the build cache.
Luckily, that's not a problem: we run `go install std cmd` right after,
so all standard library packages will be installed as object files.
Move the checkNotStale call after that install command.

There is a TODO comment that checking hidden visibility is
probably not the right thing to do. I think it is indeed not. Here
we are not referencing symbols across DSO boundaries, just within
an executable binary. The hidden visibility is for references from
another DSO. So it doesn't actually matter.
This makes cgo internal linking tests work on ARM64 with newer
GCC. It failed and was disabled due to a visibility hidden symbol
in libgcc.a that we didn't handle correctly. Specifically, the
problem is that we didn't mark visibility hidden symbol references
SXREF, which caused the loader to not think it is an unresolved
external symbol, which in turn made it not loading an object file
from the libgcc.a archive which contains the actual definition.
Later stage when we try to resolve the relocation, we couldn't
resolve it. Enable the test as it works now.

'go tool dist env' outputs different (and fewer) environment variables
than 'go env'. The 'go tool dist env' variables should be
authoritative, whereas many printed by 'go env' are merely
informational (and not intended to be overridden in the actual
environment).

Also update cmd/dist to avoid setting gcflags and ldflags explicitly
when the set of flags to be set is empty (a verbose way of specifying
the default behavior).
Stamping was disabled for the Go standard library in CL 356014 due to
the cmd/dist flags causing cmd/go to (correctly) report the resulting
binaries as stale.
With cmd/dist fixed, we can also remove the special case in cmd/go,
which will allow tests of binaries in 'cmd' to read the build info
embedded in the test binary. That build info may be useful to
determine (say) whether runtime.GOROOT ought to work without GOROOT
set in the environment.

Knowing whether test failures are correlated with specific CPU models on
has proven useful on several issues. Log it for prior to testing so it
is always available.
internal/sysinfo provides the CPU model, but it is not available in the
bootstrap toolchain, so we can't access this in cmd/dist. Instead use a
separate binary which cmd/dist will only build once testing begins.
The addition of new data to the beginning of cmd/dist output will break
x/build/cmd/coordinator's banner parsing, leaving extra lines in the log
output, though information will not be lost.
https://golang.org/cl/372538 fixes up the coordinator and should be
submitted and deployed before this CL is submitted.
This is a redo of CL 371474. It switches back to the original approach
of using a separate binary, as the bootstap toolchain won't allow
cmd/dist to import internal packages.

CL 383554 disables testing cgo internal linking on all ARM64 but
Windows, because it doesn't work with newer GCC. But
- darwin-arm64 works, and it does not use GCC
- we don't support cgo internal linking on windows-arm64 anyway.
This CL fixes the condition.

The previous workaround for issue #39466 only disabled this test for
Linux. However, the issue manifests for all arm64 systems with gcc 9.4
and above. The new netbsd-arm64 builder uses NetBSD-current with gcc
10.3, so it fails in the same way.

The amd64/arm64 relocation processing is used as a template
and updated for ppc64le.
This requires updating the TOC relocation handling code to
support linux type TOC relocations too (note, AIX uses
TOC-indirect accesses).
Noteably, the shared flag of go functions is used as a proxy
for the local entry point offset encoded in elf objects. Functions
in go ppc64le shared objects always[1] insert 2 instructions to
regenerate the TOC pointer.
[1] excepting a couple special runtime functions, see preprocess
in obj9.go for specific details of this behavior.

This should be a no-op, but if the sharded builders are for some
reason distributing stale snapshots — or testing them with mismatched
environments — this should catch them out at a relatively low cost
(#24300 notwithstanding).
Given the frequently at which (*tester).runPending already checks for
staleness, we do not expect the impact of this extra check to be
significant for most builders.
