Peter Collingbourne 1deff3dca1 Use movq for 64-bit operations
The EXTRACT_WORDS64 and INSERT_WORDS64 macros use movd for a 64-bit
operation.  Somehow gcc manages to turn this into movq, but LLVM won't.

2013-05-15  Peter Collingbourne  <pcc@google.com>

	* sysdeps/x86_64/fpu/math_private.h (MOVQ): New macro.
	(EXTRACT_WORDS64) Use where appropriate.
	(INSERT_WORDS64) Likewise.

Peter Collingbourne 791f3ba0db Use x constraints for operands to vfmaddss and vfmaddsd
While these instructions accept memory operands, only one operand
may be a memory operand.  Giving two operands xm constraints gives
the compiler the option of using memory for both operands, which
would result in invalid assembly code.  Using x for all operands is
more appropriate, as most x86_64 calling conventions will pass the
arguments in registers anyway.

2013-05-15  Peter Collingbourne  <pcc@google.com>

	* sysdeps/x86_64/fpu/multiarch/s_fma.c (__fma_fma4): Replace xm
	constraints with x constraints.
	* sysdeps/x86_64/fpu/multiarch/s_fmaf.c (__fmaf_fma4): Likewise.

Peter Collingbourne 39b1f6172a Move _obstack_compat out of common
it is impossible to create an alias of a common symbol (as
compat_symbol does), because common symbols do not have a section or
an offset until linked.  GNU as tolerates aliases of common symbols by
simply creating another common symbol, but other assemblers (notably
LLVM's integrated assembler) are less tolerant.

2013-05-15  Peter Collingbourne  <pcc@google.com>

	* malloc/obstack.c (_obstack_compat): Add initializer.

Carlos O'Donell 141af660d8 Add comments to vDSO hwcap loading process.
Loading of the vDSO pseudo-hwcap from the type 2 GNU note is
a rather arcane and poorly documented process. Given that I had
a chance to review this code today I thought I would add all
of the things I had to lookup to verify the validity of the
process.

With a single .note.GNU the vDSO can register up to 64 flags,
though in practice you are limited to 64 - _DL_FIRST_EXTRA
bits which on x86 is 12 bits.

The only use of this that I know of is in the Xen support
in Linux where they use the 1st bit to indicate "nosegneg".
I see "We use bit 1 to avoid bugs in some versions of glibc
when bit 0 is used; the choice is otherwise arbitrary.", but
no reference to a glibc bug anywhere. The code as-is should
support bit zero, so we still have that free for future use.

The kernel, glibc, and ld.so.cache must coordinate to ensure
that bit values don't go too high and are used consistently.

Siddhesh Poyarekar 43fe811b73 Use HP_TIMING for benchmarks if available
HP_TIMING uses native timestamping instructions if available, thus
greatly reducing the overhead of recording start and end times for
function calls.  For architectures that don't have HP_TIMING
available, we fall back to the clock_gettime bits.  One may also
override this by invoking the benchmark as follows:

  make USE_CLOCK_GETTIME=1 bench

and get the benchmark results using clock_gettime.  One has to do
`make bench-clean` to ensure that the benchmark programs are rebuilt.
