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.
Fixes#10324.

A typo in the previous revision ("act" instead of "oldact") caused us
to return the sa_flags from the new (or zeroed) sigaction rather than
the old one.
In the presence of a signal handler registered before

important sa_flags (such as SA_SIGINFO) in its attempt to re-register
the existing handler with SA_ONSTACK.

There are a few problems from change 35494, discovered during testing
of change 37852.
1. I was confused about the usage of n.key in the sema variant, so we
were looping on the wrong condition. The error was not caught by
the TryBots (presumably due to missing TSAN coverage in the BSD and
darwin builders?).
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
broken up into smaller chunks with a yield at the end of each
chunk.

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.
With this CL, both darwin/arm and darwin/arm64 passes all.bash.
This CL replaces CL 34926, CL 35152 as well as the fixup CL
35123 and CL 35255. They are reverted in CLs earlier in the

From the garbage collector's perspective, time can move backwards in
cgocall. However, in the midst of this time warp, the pointer
arguments to cgocall can go from dead back to live. If a stack growth
happens while they're dead and then a GC happens when they become live
again, GC can crash with a bad heap pointer.
Specifically, the sequence that leads to a panic is:
1. cgocall calls entersyscall, which saves the PC and SP of its call
site in cgocall. Call this PC/SP "X". At "X" both pointer arguments
are live.
2. cgocall calls asmcgocall. Call the PC/SP of this call "Y". At "Y"
neither pointer argument is live.
3. asmcgocall calls the C code, which eventually calls back into the
Go code.
4. cgocallbackg remembers the saved PC/SP "X" in some local variables,
calls exitsyscall, and then calls cgocallbackg1.
5. The Go code causes a stack growth. This stack unwind sees PC/SP "Y"
in the cgocall frame. Since the arguments are dead at "Y", they are
not adjusted.
6. The Go code returns to cgocallbackg1, which calls reentersyscall
with the recorded saved PC/SP "X", so "X" gets stashed back into
gp.syscallpc/sp.
7. GC scans the stack. It sees there's a saved syscall PC/SP, so it
starts the traceback at PC/SP "X". At "X" the arguments are considered
live, so it scans them, but since they weren't adjusted, the pointers
are bad, so it panics.
This issue started as of commit ca4089ad, when the compiler stopped
marking arguments as live for the whole function.
Since this is a variable liveness issue, fix it by adding KeepAlive
calls that keep the arguments live across this whole time warp.
The existing issue7978 test has all of the infrastructure for testing
this except that it's currently up to chance whether a stack growth
happens in the callback (it currently only happens on the
linux-amd64-noopt builder, for example). Update this test to force a
stack growth, which causes it to fail reliably without this fix.
Fixes#17785.

Use an explicit ./ to make sure we link against the libgo.so we just
built, not some other libgo.so that the compiler or linker may decide to
seek out.
