bae90c989c libgo: Merge from revision 18783:00cce3a34d7e of master library. 
This revision was committed January 7, 2014.  The next
revision deleted runtime/mfinal.c.  That will be done in a
subsequent merge.

This merge changes type descriptors to add a zero field,
pointing to a zero value for that type.  This is implemented
as a common variable.

	* go-gcc.cc (Gcc_backend::implicit_variable): Add is_common and
	alignment parameters.  Permit init parameter to be NULL.

9a85ed03da runtime: add the --without-libatomic configure option 
This adds the --without-libatomic configure option, which is useful for building libgo
with a non-gcc compiler.

It disables libgo's dependency on libatomic. This
is useful for platforms where it is known that the libatomic runtime
functions are not required, or where the compiler automatically
provides an implementation of them.

d76a1885bd runtime: disable split stacks for runtime_printf function under Clang 
LLVM's code generator does not currently support split stacks for vararg
functions, so we disable split stacks for the only function that uses this
feature under Clang. This appears to be OK as long as:
- this function only calls non-inlined, internal-linkage (hence no dynamic
  loader) functions compiled with split stacks (i.e. go_vprintf), which can
  allocate more stack space as required;
- this function itself does not occupy more than BACKOFF bytes of stack space
  (see libgcc/config/i386/morestack.S).
These conditions are currently known to be satisfied by Clang on x86-32 and
x86-64. Note that signal handlers receive slightly less stack space than they
would normally do if they happen to be called while this function is being
run. If this turns out to be a problem we could consider increasing BACKOFF.

PR go/60931

runtime: Fix garbage collector issue with non 4kB system page size

The go garbage collector tracks memory in terms of 4kB pages.
Most of the code checks getpagesize() at runtime and does the
right thing.

On a 64kB ppc64 box I see SEGVs in long running processes
which has been diagnosed as a bug in scavengelist.
scavengelist does a madvise(MADV_DONTNEED) without rounding
the arguments to the system page size.  A strace of one of the
failures shows the problem:

madvise(0xc211030000, 4096, MADV_DONTNEED) = 0

The kernel rounds the length up to 64kB and we mark 60kB of
valid data as no longer needed.

Round start up to a system page and end down before calling
madvise.

9c48398f49 runtime: Fix GC bug caused by Entersyscall modifying reg. 
This patch fixes a rare but serious bug.  The Go garbage
collector only examines Go stacks.  When Go code calls a
function that is not written in Go, it first calls
syscall.Entersyscall.  Entersyscall records the position of
the Go stack pointer and saves a copy of all the registers.
If the garbage collector runs while the thread is executing
the non-Go code, the garbage collector fetches the stack
pointer and registers from the saved location.

Entersyscall saves the registers using the getcontext
function.  Unfortunately I didn't consider the possibility
that Entersyscall might itself change a register before
calling getcontext.  This only matters for callee-saved
registers, as caller-saved registers would be visible on the
saved stack.  And it only matters if Entersyscall is compiled
to save and modify a callee-saved register before it calls
getcontext.  And it only matters if a garbage collection
occurs while the non-Go code is executing.  And it only
matters if the only copy of a valid Go pointer happens to be
in the callee-saved register when Entersyscall is called.
When all those conditions are true, the Go pointer might get
collected incorrectly, leading to memory corruption.

This patch tries to avoid the problem by splitting
Entersyscall into two functions.  The first is a simple
function that just calls getcontext and then calls the rest of
Entersyscall.  This should fix the problem, provided the
simple Entersyscall function does not itself modify any
callee-saved registers before calling getcontext.  That seems
to be true on the systems I checked.  But since the argument
to getcontext is an offset from a TLS variable, it won't be
true on a system which needs to save callee-saved registers in
order to get the address of a TLS variable.  I don't know why
any system would work that way, but I don't know how to rule
it out.  I think that on any such system this will have to be
implemented in assembler.  I can't put the ucontext_t
structure on the stack, because this function can not split
stacks, and the ucontext_t structure is large enough that it
could cause a stack overflow.

91d6f071fb runtime: Use a better heap location on arm64 systems. 
Before this, the heap location used on a 64-bit system was not
available to user-space on arm64, so the "32-bit" strategy ended up
being used.  So use somewhere that is available, and for bonus points
is far away from where the kernel allocates address space by default.

abd471378c runtime: fix 32-bit malloc for pointers >= 0x80000000 
The spans array is allocated in runtime_mallocinit.  On a
32-bit system the number of entries in the spans array is
MaxArena32 / PageSize, which (2U << 30) / (1 << 12) == (1 << 19).
So we are allocating an array that can hold 19 bits for an
index that can hold 20 bits.  According to the comment in the
function, this is intentional: we only allocate enough spans
(and bitmaps) for a 2G arena, because allocating more would
probably be wasteful.

But since the span index is simply the upper 20 bits of the
memory address, this scheme only works if memory addresses are
limited to the low 2G of memory.  That would be OK if we were
careful to enforce it, but we're not.  What we are careful to
enforce, in functions like runtime_MHeap_SysAlloc, is that we
always return addresses between the heap's arena_start and
arena_start + MaxArena32.

We generally get away with it because we start allocating just
after the program end, so we only run into trouble with
programs that allocate a lot of memory, enough to get past
address 0x80000000.

This changes the code that computes a span index to subtract
arena_start on 32-bit systems just as we currently do on
64-bit systems.

this case by assuming that the connect succeeded.  This code
is weird enough that it is implemented as Solaris-only so that
it doesn't hide a real error on a different OS.

net: use DialTimeout in TestSelfConnect

Backported from master repository.

This avoids problems with systems that take a long time to
find out nothing is listening, while still testing for the
self-connect misfeature since a self-connect should be fast.
With this we may be able to remove the test for non-Linux
systems.

Tested (on GNU/Linux) by editing selfConnect in
tcpsock_posix.go to always return false and verifying that
TestSelfConnect then fails with and without this change.

fdbc38a6e8 compiler, runtime: Use function descriptors. 
This changes the representation of a Go value of function type
from being a pointer to function code (like a C function
pointer) to being a pointer to a struct.  The first field of
the struct points to the function code.  The remaining fields,
if any, are the addresses of variables referenced in enclosing
functions.  For each call to a function, the address of the
function descriptor is passed as the last argument.

This lets us avoid generating trampolines, and removes the use
of writable/executable sections of the heap.

The mmap() call which reserves the arena should have MAP_NORESERVE
flag as in typical cases this memory will never be (fully) needed.
This matters in environments which do not do Linux style memory
overcommit, such as OpenIndiana/OpenSolaris/Solaris.

The MAP_NORESERVE flag does not exist on all operating systems
(for example FreeBSD). Therefore we define it to zero value in
case it does not exist.

85c2f96c1c syscall: fix creds_test to reliably close os.File 
Uncovered by Uros Bizjak.

Before this patch the test would close the file descriptor but
not the os.File.  When the os.File was GC'ed, the finalizer
would close the file descriptor again.  That would cause
problems if the same file descriptor were returned by a later
call to open in another test.

On my system:

> GOGC=30 go test
--- FAIL: TestPassFD (0.04 seconds)
passfd_test.go:62: 	FileConn: dup: bad file descriptor
