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().

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.

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.

This sequence is concerned only with moving code, not changing

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.

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.

Per discussion on #12808, it's a bit odd that if you do

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.

The go_test_bench:* tests run:

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

Should save 90-180 seconds. (or maybe 45 seconds for trybots, since

While we're here, make sure pending tasks are flushed before running
the host tests. If not, the "##### misc/cgo/testcarchive" banner
and "PASS" won't show up in the all.bash output.

The c-archive test were recently converted from shell script to Go.
Unfortunately, it also lost the ability to target iOS and Android
that lack C compilers and require exec wrappers.
Compile the c-archive test for the host and run it with the target
GOOS/GOARCH environment. Change the test to rely on go env GOOS
and go env GOARCH instead of runtime.GOOS and runtime.GOARCH.
Fixes#8345

Unfortunately, dist does not (yet) support tests running off the host

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.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.
Go policy has been single space after periods in comments for some time.
The copyright header template at:
https://golang.org/doc/contribute.html#copyright
also uses a single space.
Make them all consistent.

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.

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.)

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.
