b679e31cdb test/bench: delete
Russ added test/bench/go1 in CL 5484071 to have a stable suite of
programs to use as benchmarks. For the compiler and runtime we had
back then, those were reasonable benchmarks, but the compiler and
runtime are now far more sophisticated and these benchmarks no longer
have good coverage. We also now have better benchmark suites
maintained outside the repo (e.g., golang.org/x/benchmarks). Keeping
test/bench/go1 at this point is actively misleading.

Indirectly related to #37486, as this also removes the last package
dist test runs outside of src/.

b26c3927bd cmd/dist: drop host test support
Host tests are used for emulated builders that use cross-compilation.
Today, this is the android-{386,amd64}-emu builders and all wasm
builders. These builders run all.bash on a linux/amd64 host to build
all packages and most tests for the emulated guest, and then run the
resulting test binaries inside the emulated guest. A small number of
test packages are “host tests”: these run on the host rather than the
guest because they invoke the Go toolchain themselves (which only
lives on the host) and run the resulting binaries in the guest.

However, this host test mechanism is barely used today, despite being
quite complex. This complexity is also causing significant friction to
implementing structured all.bash output.

As of this CL, the whole host test mechanism runs a total of 10 test
cases on a total of two builders (android-{386,amd64}-emu). There are
clearly several tests that are incorrectly being skipped, so we could
expand it to cover more test cases, but it would still apply to only
two builders. Furthermore, the two other Android builders
(android-{arm,arm64}-corellium) build the Go toolchain directly inside
Android and also have access to a C toolchain, so they are able to get
significantly better test coverage without the use of host tests. This
suggests that the android-*-emu builders could do the same. All of
these tests are cgo-related, so they don't run on the wasm hosts
anyway.

Given the incredibly low value of host tests today, they are not worth
their implementation complexity and the friction they cause. Hence,
this CL drops support for host tests. (This was also the last use of
rtSequential, so we drop support for sequential tests, too.)

Fixes #59999.

689041160f cmd/dist,internal/testdir: more cooperative host test mechanism
On cross-compiling builder machines, we run internal/testdir on the
host, where it can access the Go toolchain to build binaries for the
guest and run them through an exec wrapper. Currently this uses dist
test's existing host test mechanism, which is quite complicated and we
are planning to eliminate (#59999).

Switch internal/testdir to use a more cooperative mechanism. With this
CL, dist still understands that it has to build and run the test using
the host GOOS/GOARCH, but rather than doing complicated manipulation
of environment variables itself, it passes the guest GOOS/GOARCH to
the test, which can easily inject it into its environment. This means
dist test can use "go test" directly, rather than having to split up
the build and run steps.

For #37486.

b6c75c5fb1 test,internal/testdir: don't set GOOS/GOARCH
The test directory driver currently sets the GOOS/GOARCH environment
variables if they aren't set. This appears to be in service of a
single test, test/env.go, which was introduced in September 2008 along
with os.Getenv. It's not entirely clear what that test is even trying
to check, since runtime.GOOS isn't necessarily the same as $GOOS. We
keep the test around because golang.org/x/tools/go/ssa/interp uses it
as a test case, but we simplify the test and eliminate the need for
the driver to set GOOS/GOARCH.

2484e1331a misc/swig: restructure as a driver
Currently, the misc/swig tests directly use Swig and C++ and will fail
to build if either Swig or a C++ compiler are not present. Typically,
we hide this fact from users because dist test itself checks for Swig
and a C++ compiler before even attempting to run this test, though
users will see this is they try to go test ./... from misc.

However, we're about to move the misc/swig tests into the cmd module,
where they will be much more visible and much more likely to run
unintentionally. To prevent build errors, this CL restructures these
tests into a single pure Go test plus two test packages hidden in
testdata. This is relatively easy to do for this test because there
are only four test cases total. The pure Go test can check for the
necessary build tools before trying to build and run the tests in
testdata. This also gives us the opportunity to move the LTO variant
of these tests out of dist and into the test itself, simplifying dist.

For #37486.

af64b75b67 misc/cgo/test: add cgo build constraints
We're about to move this package to cmd/cgo/internal, where it will
get caught up in the "CGO_ENABLED=0 go install cmd" done by make.bash.
Currently, building this package with CGO_ENABLED=0 fails because it
contains several source files that don't themselves import "C", but do
import a subdirectory where that package imports "C" and thus has no
exported API.

Fix the CGO_ENABLED=0 build of this package by adding the necessary
cgo build tags. Not all source files need it, but this CL makes
"CGO_ENABLED=0 go test -c" work in this package.

a76b073712 misc/cgo/test: fix vet error
Vet's cgocall check fails on misc/cgo/test with "possibly passing Go
type with embedded pointer to C". This error is confusing, but the
cgocall check is looking for passing pointers to Go slices to C, which
is exactly what this test is doing. Normally we don't notice this
because vet doesn't run on misc, but we're about to move this test to
cmd/cgo/internal, where vet will start failing.

I'm not sure why we're passing a pointer to a slice here. It's
important that we call a C function with an unsafe.Pointer to memory
containing a pointer to test #25941 and that the result is this call
is then passed to another C function for #28540. This CL maintains
these two properties without the use of a slice.

For #37486.

trivial rename and updating dist/test.go for the new paths, plus

This will let these tests access facilities in internal/testenv.

d740b365b7 cmd/compile/internal/pgo: move pprof graph to internal package
graph.go is a simplified fork of github.com/google/pprof/internal/graph,
which is used as an intermediate data structure to construct the final
graph exported by package pgo (IRGraph).

Exporting both is a bit confusing as the former is unused outside of the
package. Since the naming is also similar, move graph.go to its own
package entirely.

c2becd70c5 cmd/link: check DWARF section sizes separately
Currently, we check the total size of all data+DWARF sections
doesn't exceed 2 GB, which doesn't make sense. We should check
data and DWARF separately. And for DWARF, check each section
separately, as we use section offset for references.

472f623482 net: force cgo for myhostname and mdns nss modules for LookupAddr on unix
Currently there is a small bug in the LookupAddr for unix systems
that causes the use of go resolver instead of the cgo one.
Example for nss myhostname:

func main() {
        fmt.Println(net.LookupAddr(os.Args[1]))
}

root@arch:~# cat /etc/nsswitch.conf | grep host
hosts:          myhostname dns
root@arch:~# GODEBUG=netdns=+3 go run main.go 192.168.1.200
go package net: confVal.netCgo = false  netGo = false
go package net: dynamic selection of DNS resolver
go package net: hostLookupOrder() = dns
[] lookup 200.1.168.192.in-addr.arpa. on 8.8.8.8:53: no such host
root@arch:~# GODEBUG=netdns=go+3 go run main.go 192.168.1.200
go package net: confVal.netCgo = false  netGo = true
go package net: GODEBUG setting forcing use of Go's resolver
go package net: hostLookupOrder() = dns
[] lookup 200.1.168.192.in-addr.arpa. on 8.8.8.8:53: no such host
root@arch:~# GODEBUG=netdns=cgo+3 go run main.go 192.168.1.200
go package net: confVal.netCgo = true  netGo = false
go package net: using cgo DNS resolver
go package net: hostLookupOrder() = cgo
[arch] <nil>

The problem come from that we are only checking for hostnames that the
myhostname can resolve, but not for the addrs that it can also.

man  nss-myhostname:
       Please keep in mind that nss-myhostname (and nss-resolve) also
       resolve in the other direction — from locally attached IP
       addresses to hostnames.

bc9e21351c runtime: rename getcallerfp to getfp
The previous name was wrong due to the mistaken assumption that calling
f->g->getcallerpc and f->g->getcallersp would respectively return the
pc/sp at g. However, they are actually referring to their caller's
caller, i.e. f.

Rename getcallerfp to getfp in order to stay consistent with this
naming convention.

Also see discussion on CL 463835.
