build: fix check for selinux's allow_execstack on Fedora 16 · 90c50700

Bobby Powers authored Nov 11, 2011

Fedora 16 mounts selinux at /sys/fs/selinux, instead of the
traditional /selinux.  Check both locations for the selinux
filesystem in make.bash

net, io/ioutil: remove use of os.Time · a6c501e4

Anthony Martin authored Nov 11, 2011

I had to replace the single use of io/ioutil
in the time package with a bytes.Buffer since
there would've been a dependency cycle.

There are no other uses of os.Time.

exp/terminal: rename shell to terminal and add SetSize · 252ef18d

Adam Langley authored Nov 11, 2011

It was never really a shell, but the name carried
over from SSH's ServerShell.

Two small functional changes:

Add SetSize, which allows the size of the terminal
to be changed in response, say, to an SSH message.

Don't write the prompt if there's already something
on the current line.

godefs: delete, replaced by cgo -godefs · 879a1c6a

Russ Cox authored Nov 10, 2011

Godefs was a C program that ran gcc and then parsed the
stabs debugging information in the resulting object file to
generate C or Go code for bootstrapping as part of
package runtime or package syscall.

Cgo does the same work, but using the dwarf debugging
information.  Add -godefs and -cdefs options to cgo that
mimic godefs's output, albeit with different input
(a Go program, not a C program).

This has been a "nice to have" for a while but was forced
by Apple removing stabs debugging output from their
latest compilers.

Fixes #835.
Fixes #2338.

6l: add MOVQ xmm_reg, xmm_reg · 17105870

Michał Derkacz authored Nov 09, 2011

Added handler for:
        MOVQ xmm_reg, xmm_reg/mem64
        MOVQ xmm_reg/mem64, xmm_reg
using native MOVQ (it take precedence above REX.W MOVD)
I don't understood 6l code enough to be sure that my small changes
didn't broke it. But now 6l works with MOVQ xmm_reg, xmm_reg and
all.bash reports "0 unexpected bugs".

There is test assembly source:
MOVQ    X0, X1
MOVQ    AX, X1
MOVQ    X1, AX
MOVQ    xxx+8(FP), X2
MOVQ    X2, xxx+8(FP)

and generated code (gdb disassemble /r):

0x000000000040f112 <+0>:   f3 0f 7e c8        movq  %xmm0,%xmm1
0x000000000040f116 <+4>:   66 48 0f 6e c8     movq  %rax,%xmm1
0x000000000040f11b <+9>:   66 48 0f 7e c8     movq  %xmm1,%rax

0x000000000040f126 <+20>:  66 0f d6 54 24 10  movq  %xmm2,0x10(%rsp)

runtime: add timer support, use for package time · 3b860269

Russ Cox authored Nov 09, 2011

This looks like it is just moving some code from
time to runtime (and translating it to C), but the
runtime can do a better job managing the goroutines,
and it needs this functionality for its own maintenance
(for example, for the garbage collector to hand back
unused memory to the OS on a time delay).
Might as well have just one copy of the timer logic,
and runtime can't depend on time, so vice versa.

It also unifies Sleep, NewTicker, and NewTimer behind
one mechanism, so that there are no claims that one
is more efficient than another.  (For example, today
people recommend using time.After instead of time.Sleep
to avoid blocking an OS thread.)

Fixes #1644.
Fixes #1731.
Fixes #2190.
