fb54abe9ce all: correct location of go tool
In general, there are no guarantee that `go` command exist on $PATH.
This CL tries to get `go` command from $GOROOT/bin instead.

There are three kinds of code we should handle:
    For normal code, the CL implements goCmd() or goCmdName().
    For unit tests, the CL uses testenv.GoTool() or testenv.GoToolPath().
    For integration tests, the CL sets PATH=$GOROOT/bin:$PATH in cmd/dist.

Note that make.bash sets PATH=$GOROOT/bin:$PATH in the build process.
So this change is only useful when we use toolchain manually.

Updates #21875

GOTRACEBACK=2 already set in their environment. Environment-sensitive
test are awkward, and in this case there is a very simple workaround:

1. remove broken verification
   The runtime check assumes that no-pcln symbol entry have zero value,
   but the linker emit no entries if the symbol is no-pcln.
   As a result, if there are no-pcln symbols at the very end of pcln
   table, it will panic.
2. correct condition of export
   Handle special chracters in pluginpath correcty.
   Export "go.itab.*", so different plugins can share the same itab.

06f4d93699 cmd/go: put computed GOROOT in built binaries
As of CL 42533, cmd/go will recompute its GOROOT based on the
location of its own executable. This CL plumbs that computed GOROOT
into every binary it builds using the linker -X flag. This
means binaries built with a moved cmd/go will report the GOROOT
they were built in from runtime.GOROOT().

3e7abf82e3 cmd/go,cmd/link: support buildmode c-shared on ppc64le
This change enables buildmode c-shared on ppc64le.

A bug was fixed in runtime/rt0_linux_ppc64le.s that was necessary to
make this work.  In _rt0_ppc64le_linux_lib, there is code to store
the value of r2 onto the caller's stack.  However, if this file
is compiled using a build mode that maintains the TOC address in
r2, then instructions will be inserted at the beginning of this
function to generate the r2 value for the callee, not the caller.
That means the r2 value for the callee is stored onto the caller's
stack.  If caller and callee don't have the same r2 values, then
the caller will restore the wrong r2 value after it returns.  This
situation can happen when using dlopen since the caller of this
function will be in ld64.so and will definitely have a different
TOC.

69972aea74 internal/cpu: new package to detect cpu features
Implements detection of x86 cpu features that
are used in the go standard library.

Changes all standard library packages to use the new cpu package
instead of using runtime internal variables to check x86 cpu features.

Updates: #15403

a93e9f0fad cmd/dist: spin up fewer test dir runners
5 shards, each of which spins up NumCPU processes,
each of which is running at GOMAXPROCS=NumCPU,
is too much for one machine. It makes my laptop unusable.

It might also be in part responsible for test flakes
that require a moderately responsive system,
like #18589 (backedge scheduling) and #19276 (locklinear).

It's possible that Go should be a better neighbor in general;
that's #17969. In the meantime, fix this corner of the world.

Builders snapshot the world and run shards on different
machines, so keeping sharding high for them is good.

This is a partial reversion of CL 18199.

Fixes #20141.

7fc82104ea cmd/go, cmd/dist: temporarily disable race and PIE internal link tests on Alpine
In an effort to at least understand the complete set of things not
working on Alpine Linux, I've been trying to get the build passing
again, even with tests disabled.

The race detector is broken on Alpine. That is #14481 (and #9918).
So disable those tests for now.

Also, internal linking with PIE doesn't work on Alpine yet.
That is #18243. So disable that test for now.

With this CL, all.bash almost passes. There's some cgo test failing
still, but there's no bug yet, so that can be a separate CL.

11c7b4491b os: fix race between file I/O and Close
Now that the os package uses internal/poll on Unix and Windows systems,
it can rely on internal/poll reference counting to ensure that the
file descriptor is not closed until all I/O is complete.

That was already working. This CL completes the job by not trying to
modify the Sysfd field when it might still be used by the I/O routines.

Fixes #7970

1e3570ac86 cmd/internal/objabi: extract shared functionality from obj
Now only cmd/asm and cmd/compile depend on cmd/internal/obj. Changing
the assembler backends no longer requires reinstalling cmd/link or
cmd/addr2line.

There's also now one canonical definition of the object file format in
cmd/internal/objabi/doc.go, with a warning to update all three
implementations.

objabi is still something of a grab bag of unrelated code (e.g., flag
and environment variable handling probably belong in a separate "tool"
package), but this is still progress.

Fixes #15165.
Fixes #20026.

c253ea47e1 cmd/dist: require _ before GOOS and GOARCH when building bootstrap
Currently, dist allows GOOS and GOARCH to appear as *any* substring in
a file name when selecting source files to go into go_bootstrap. This
was necessary prior to Go 1.4, where it needed to match names like
"windows.c", but now it's gratuitously different from go/build. This
led to a bug chase to figure out why "stubs_nonlinux.go" was not being
built on non-Linux OSes.

Change shouldbuild to require an "_" before the GOOS and GOARCH in a
file name. This is still less strict than go/build, but the behavior
is much closer.

- to break cycles, for now we need two functions to convert between
  *gc.Node and *types.Node (the latter is a dummy type)
- adjusted the gc's code to use the new package and the conversion
  functions as needed
- made several Pkg, Sym, and Type methods functions as needed
- renamed constructors typ, typPtr, typArray, etc. to types.New,
  types.NewPtr, types.NewArray, etc.

Fix the dist check from gohostos to goos accordingly.

The error was masked on the builders because they run on a darwin host
where the sanitizers tests never ran.

With this change, the Android test suite completes successfully on
Android/amd64.

c1ada22bc1 cmd/go, plugin: disable plugins on darwin
We are seeing a bad stack map in #18190. In a copystack, it is
mistaking a slot for a pointer.

Presumably this is caused either by our fledgling dynlink support on
darwin, or a consequence of having two copies of the runtime in the
process. But I have been unable to work out which in the 1.8 window,
so pushing darwin support to 1.9 or later.

b906df653b os/exec: add closeOnce.WriteString method
Add an explicit WriteString method to closeOnce that acquires the
writers lock.  This overrides the one promoted from the
embedded *os.File field.  The promoted one naturally does not acquire
the lock, and can therefore race with the Close method.

Fixes #17647.

0ba3c607df cmd/dist, go/build: make CGO_ENABLED during make.bash sticky
Per discussion on #12808, it's a bit odd that if you do

	CGO_ENABLED=0 ./make.bash

then you get a toolchain that still tries to use cgo.
So make the CGO_ENABLED setting propagate into
the resulting toolchain as the default setting for that
environment variable, like we do with other variables
like CC and GOROOT.

No reasonable way to test automatically, but I did
test by hand that after the above command, 'go env'
shows CGO_ENABLED=0; before it showed CGO_ENABLED=1.

Fixes #12808.

3ead49989e cmd/dist: skip compiling 100 packages without benchmarks in race mode
The go_test_bench:* tests run:

    go test -short -race -run=^$ -benchtime=.1s -cpu=4 $PKG

... on each discovered package with any tests. (The same set used for
the "go_test:*" tests)

That set was 168 packages:

$ go tool dist test -list | grep go_test: | wc -l
168

But only 76 of those have a "func Benchmark", and running each
"go_test_bench:" test and compiling it in race mode, just to do
nothing took 1-2 seconds each.

So stop doing that and filter out the useless packages earlier. Now:

$ go tool dist test -list -race | grep go_test_bench:  | wc -l
76

Should save 90-180 seconds. (or maybe 45 seconds for trybots, since
they're sharded)

s390x does not require duffzero/duffcopy since it has
storage-to-storage instructions that can copy/clear up to 256
bytes at a time.

peep contains several new passes to optimize instruction
sequences that match s390x instructions such as the
compare-and-branch and load/store multiple instructions.

copyprop and subprop have been extended to work with moves that
require sign/zero extension. This work could be ported to other
architectures that do not used sized math however it does add
complexity and will probably be rendered unnecessary by ssa in
the near future.

Information about CPU architectures (e.g., name, family, byte

scattered around the source tree. Instead consolidate the basic
information into a single new package cmd/internal/sys.

Also, introduce new sys.I386, sys.AMD64, etc. names for the constants
'8', '6', etc. and replace most uses of the latter. The notable
exceptions are a couple of error messages that still refer to the old
char-based toolchain names and function reltype in cmd/link.

Make sure that for any DLL that Go uses itself, we only look for the
DLL in the Windows System32 directory, guarding against DLL preloading
attacks.

(Unless the Windows version is ancient and LoadLibraryEx is
unavailable, in which case the user probably has bigger security
problems anyway.)

This does not change the behavior of syscall.LoadLibrary or NewLazyDLL
if the DLL name is something unused by Go itself.

This change also intentionally does not add any new API surface. Instead,
x/sys is updated with a LoadLibraryEx function and LazyDLL.Flags in:

fdba5a7544 all: delete dead non-test code
This change removes a lot of dead code. Some of the code has never been
used, not even when it was first commited. The rest shouldn't have
survived refactors.

This change doesn't remove unused routines helpful for debugging, nor
does it remove code that's used in commented out blocks of code that are
only unused temporarily. Furthermore, unused constants weren't removed
when they were part of a set of constants from specifications.

One noteworthy omission from this CL are about 1000 lines of unused code
in cmd/fix, 700 lines of which are the typechecker, which hasn't been
used ever since the pre-Go 1 fixes have been removed. I wasn't sure if
this code should stick around for future uses of cmd/fix or be culled as
well.

This is intended to help debug compiler problems that pop
up in the bootstrap phase of make.bash.  GO_GCFLAGS does not
normally apply there.  Options-for-all phases is intended
to allow crude tracing (and full timing) by turning on timing
for all phases, not just one.

Phase names can also be specified using a regular expression,
for example
BOOT_GO_GCFLAGS=-d='ssa/~^.*scc$/off' \
GO_GCFLAGS='-d=ssa/~^.*scc$/off' ./make.bash

I just added this because it was the fastest way to get
me to a place where I could easily debug the compiler.

50c38d46e8 cmd/go, go/build: add support for Fortran
This change adds support for Fortran files (.f, .F, .for, .f90) to the
go tool, in a similar fashion to Objective-C/C++. Only gfortran is
supported out of the box so far but leaves other Fortran compiler
toolchains the ability to pass the correct link options via CGO_LDFLAGS.
A simple test (misc/cgo/fortran) has been added and plugged into the
general test infrastructure. This test is only enabled when the $FC
environment variable is defined (or if 'gfortran' was found in $PATH.)

Derived from CL 4114.

9aa630faa8 cmd/dist: accept "//+build" with no spaces, like go/build
The go/build parser accepts "//+build", with no spaces.
Make the cmd/dist bootstrap parser do the same.
While in theory we should always use the space form,
I copied some code that did not into the standard tree,
and I was very confused that 'go test' had had no problem
but then make.bash died.

(As a reminder, cmd/dist does not use go/build because
cmd/dist must build against earlier versions of Go.)

eb0cff9a76 [dev.ssa] Merge remote-tracking branch 'origin/master' into mergebranch
Semi-regular merge from tip to dev.ssa.

Two fixes:
1) Mark selectgo as not returning.  This caused problems
   because there are no VARKILL ops on the selectgo path,
   causing things to be marked live that shouldn't be.
2) Tell the amd64 assembler that addressing modes like
   name(SP)(AX*4) are ok.
