runtime: align stack pointer in sigfwd

2016-11-01T17:37:43+00:00

sigfwd calls an arbitrary C signal handler function.  The System V ABI
for x86_64 (and the most recent revision of the ABI for i386) requires
the stack to be 16-byte aligned.

Fixes: #17641

runtime: use clock_gettime(CLOCK_REALTIME) for nanosecond-precision time.now on arm64, mips64x

2016-10-27T17:53:13+00:00

Assembly copied from the clock_gettime(CLOCK_MONOTONIC)
call in runtime.nanotime in these files and then modified to use
CLOCK_REALTIME.

Also comment system call numbers in a few other files.

Fixes #11222.

runtime: adjust gsignal stack to current signal stack

2015-12-24T17:00:04+00:00

If non-Go code calls sigaltstack before a signal is received, use
sigaltstack to determine the current signal stack and set the gsignal
stack to use it.  This makes the Go runtime more robust in the face of
non-Go code.  We still can't handle a disabled signal stack or a signal
triggered with SA_ONSTACK clear, but we now give clear errors for those
cases.

Fixes #7227.
Update #9896.

runtime: update newosproc asm to access m.id directly

2015-11-12T23:16:33+00:00

darwin/386, freebsd/386, and linux/386 use a setldt system call to
setup each M's thread-local storage area, and they need access to the
M's id for this.  The current code copies m.id into m.tls[0] (and this
logic has been cargo culted to OSes like NetBSD and OpenBSD, which
don't even need m.id to configure TLS), and then the 386 assembly
loads m.tls[0]... but since the assembly code already has a pointer to
the M, it might as well just load m.id directly.

runtime: if we don't handle a signal on a non-Go thread, raise it

2015-07-22T20:26:29+00:00

In the past badsignal would crash the program.  In
https://golang.org/cl/10757044 badsignal was changed to call sigsend,
to fix issue #3250.  The effect of this was that when a non-Go thread
received a signal, and os/signal.Notify was not being used to check
for occurrences of the signal, the signal was ignored.

This changes the code so that if os/signal.Notify is not being used,
then the signal handler is reset to what it was, and the signal is
raised again.  This lets non-Go threads handle the signal as they
wish.  In particular, it means that a segmentation violation in a
non-Go thread will ordinarily crash the process, as it should.

Fixes #10139.
Update #11794.

cmd/internal/ld, runtime: halve tlsoffset on ELF/intel

2015-03-05T01:23:29+00:00

For OSes that use elf on intel, 2*Ptrsize bytes are reserved for TLS.
But only one pointer (g) has been stored in the TLS for a while now.
So we can set it to just Ptrsize, which happily matches what happens
when externally linking.
