We add the instructions in the compiler and assembler if -shared is used.
We were assuming that the instructions were present when building a

are the cases where the go tool would be building with -shared.
That assumption fails when using some other tool, such as Bazel,
that does not necessarily use -shared in exactly the same way.

On Android, the exec wrapper passes on output from adb to its parent
process by passing on os.Stderr and os.Stdout to adb. If the adb
process somehow hangs, it will keep stderr and stdout will open, in turn
blocking go test from ever returning from its cmd.Wait() even though
it has killed the exec wrapper process.
Break the short circuit by introducing a wrapper between adb and the
exec wrapper, preventing os/exec.Run from passing along the raw
file descriptors for os.Stdout and os.Stderr.

Prior to this CL, flags such as NOSPLIT
on ATEXT Progs were stored in From3.Offset.
Some but not all of those flags were also
duplicated into From.Sym.Attribute.
This CL migrates all of those flags into
From.Sym.Attribute and stops creating a From3.
A side-effect of this is that printing an
ATEXT Prog can no longer simply dump From3.Offset.
That's kind of good, since the raw flag value
wasn't very informative anyway, but it did
necessitate a bunch of updates to the cmd/asm tests.
The reason I'm doing this work now is that
avoiding storing flags in both From.Sym and From3.Offset
simplifies some other changes to fix the data
race first described in CL 40254.
This CL almost passes toolstash-check -all.
The only changes are in cases where the assembler
has decided that a function's flags may be altered,
e.g. to make a function with no calls in it NOSPLIT.
Prior to this CL, that information was not printed.

Compiler errors now show the exact line and line byte offset (sometimes
called "column") of where an error occured. For `go tool compile x.go`:
package p
const c int = false
//line foo.go:123
type t intg
reports
x.go:2:7: cannot convert false to type int
foo.go:123[x.go:4:8]: undefined: intg
(Some errors use the "wrong" position for the error message; arguably
the byte offset for the first error should be 15, the position of 'false',
rathen than 7, the position of 'c'. But that is an indepedent issue.)
The byte offset (column) values are measured in bytes; they start at 1,
matching the convention used by editors and IDEs.
Positions modified by //line directives show the line offset only for the
actual source location (in square brackets), not for the "virtual" file and
line number because that code is likely generated and the //line directive
only provides line information.
Because the new format might break existing tools or scripts, printing
of line offsets can be disabled with the new compiler flag -C. We plan
to remove this flag eventually.

were looping on the wrong condition. The error was not caught by

2. The sysmon goroutine sometimes skips notetsleep entirely, using
direct usleep syscalls instead. In that case, we were not calling
_cgo_yield, leading to missed signals under TSAN.
3. Some notetsleep calls have long finite timeouts. They should be

The iOS test harness was recently changed in response to lldb bugs
to replace breakpoints with the SIGUSR2 signal (CL 34926), and to
pass the current directory in the test binary arguments (CL 35152).
Both the signal sending and working directory setup is done from
the go test driver.
However, the new method doesn't work with tests where a C program is
the test driver instead of go test: the current working directory
will not be changed and SIGUSR2 is not raised.
Instead of copying that logic into any C test program, rework the
test harness (again) to move the setup logic to the early runtime
cgo setup code. That way, the harness will run even in the library
build modes.
Then, use the app Info.plist file to pass the working
directory, removing the need to alter the arguments after running.
Finally, use the SIGINT signal instead of SIGUSR2 to avoid
manipulating the signal masks or handlers.
Fixes the testcarchive tests on iOS.

the old iOS builders where their provisioning profile covers
that bundle id.
Expand the detection script to list all available provisioning
profiles for the attached device and include the bundle id in the
GOIOS_APP_ID environment variable.
To allow the old builders to continue, the "golang.gotest" bundle
id is used as a fallback if only the app id prefix is specified in
GOIOS_APP_ID.
For the new builders.

On (at least) macOS 10.12, the `security cms` subcommand used by the
iOS detection script will output an error to stderr. The command
otherwise succeeds, but the extra line confuses a later parsing step.
To fix it, use only stdout and ignore stderr from every command run
by detect.go.
For the new iOS builders.

Modules appear in the moduledata linked list in the order they are
loaded by the dynamic loader, with one exception: the
firstmoduledata itself the module that contains the runtime.
This is not always the first module (when using -buildmode=shared,
it is typically libstd.so, the second module).
The order matters for typelinksinit, so we swap the first module
with whatever module contains the main function.
Updates #18729
This fixes the test case extracted with -linkshared, and now
go test -linkshared encoding/...
passes. However the original issue about a plugin failure is not
yet fixed.

This is needed for typical tests with gccgo, as it passes the
LD_LIBRARY_PATH environment variable to the new program.

With GCC 7 (not yet released), cgo fails with errors like
./sigaltstack.go:65:8: call of non-function C.restoreSignalStack
I do not know precisely why. Explicitly declaring that there are no
arguments to the static function is a simple fix for the debug info.
