7881e1ee07 Liberation Day is no longer celebrated in Romania; rather a national
holiday is now celebrated on December 1st.  From the PR:

December 1 was adopted as National Day in 1990, being the day of
celebration of the Great Assembly of Alba Iulia which voted for the
union of Transylvania with Romania and which symbolise the union of all
Romanians within a single state and the achievement of the unity of
Romanian national state. [1]

5776f433ab Extract the high and low words together. With gcc-3.4 on uniformly
distributed non-large args, this saves about 14 of 134 cycles for
Athlon64s and about 5 of 199 cycles for AthlonXPs.

Moved the check for x == 0 inside the check for subnormals.  With
gcc-3.4 on uniformly distributed non-large args, this saves another
5 cycles on Athlon64s and loses 1 cycle on AthlonXPs.

Use INSERT_WORDS() and not SET_HIGH_WORD() when converting the first
approximation from bits to double.  With gcc-3.4 on uniformly distributed
non-large args, this saves another 4 cycles on both Athlon64s and and
AthlonXPs.

Accessing doubles as 2 words may be an optimization on old CPUs, but on
current CPUs it tends to cause extra operations and pipeline stalls,
especially for writes, even when only 1 of the words needs to be accessed.

Removed an unused variable.

c505fe7a0f Reduce Giant scope a bit, as fdrop() is believed to be MPSAFE.
The purpose of this change is consistency (not performance improvement:)),
as it was hard to tell if fdrop() is MPSAFE or not when I saw it sometimes
under the Giant and sometimes without it.

f668cd5df7 If LOADER_BZIP2_SUPPORT is defined allocate heap in the 1MB-4MB range to
provide enough room for decompression (up to 2.5MB is necessary). This
should be safe to do since we load i386 kernels after 8MB mark now, so
that 16MB is the minimum amount of RAM necessary to even boot FreeBSD.

This makes bzip2-support  practically useable.

915dad0e92 Long-long time ago, when the trees were large and memory expensive amount of
memory directly available to loader(8) and friends was limited to 640K on i386.
Those times have passed long time ago and now loader(8) can directly access
up to 4GB of RAM at least theoretically. At the same time, there are several
places where it's assumed that malloc() will only allocate memory within
first megabyte.

Remove that assumption by allocating appropriate bounce buffers for BIOS
calls on stack where necessary.

This allows using memory above first megabyte for heap if necessary.

c5964538b7 Use a minimax polynomial approximation instead of a Pade rational
function approximation for the second step.  The polynomial has degree
2 for cbrtf() and 4 for cbrt().  These degrees are minimal for the final
accuracy to be essentially the same as before (slightly smaller).
Adjust the rounding between steps 2 and 3 to match.  Unfortunately,
for cbrt(), this breaks the claimed accuracy slightly although incorrect
rounding doesn't.  Claim less accuracy since its not worth pessimizing
the polynomial or relying on exhaustive testing to get insignificantly
more accuracy.

This saves about 30 cycles on Athlons (mainly by avoiding 2 divisions)
so it gives an overall optimization in the 10-25% range (a larger
percentage for float precision, especially in 32-bit mode, since other
overheads are more dominant for double precision, surprisingly more
in 32-bit mode).

f94b154580 Bump __FreeBSD_version to 700009 because:
1. The ELF-64 typedefs are now standardized, so that the libelf port
   (devel/libelf) does not need to compensate for not having the
   Elf64_Xword and Elf64_Sxword types.
2. ELF Symbol versioning support has been added. This also affects
   the libelf port (though configure should detect this correctly).

ce804bff58 Fixed code to match comments and the algorithm:
- in preparing for the third approximation, actually make t larger in
  magnitude than cbrt(x).  After chopping, t must be incremented by 2
  ulps to make it larger, not 1 ulp since chopping can reduce it by
  almost 1 ulp and it might already be up to half a different-sized-ulp
  smaller than cbrt(x).  I have not found any cases where this is
  essential, but the think-time error bound depends on it.  The relative
  smallness of the different-sized-ulp limited the bug.  If there are
  cases where this is essential, then the final error bound would be
  5/6+epsilon instead of of 4/6+epsilon ulps (still < 1).
- in preparing for the third approximation, round more carefully (but
  still sloppily to avoid branches) so that the claimed error bound of
  0.667 ulps is satisfied in all cases tested for cbrt() and remains
  satisfied in all cases for cbrtf().  There isn't enough spare precision
  for very sloppy rounding to work:
  - in cbrt(), even with the inadequate increment, the actual error was
    0.6685 in some cases, and correcting the increment increased this
    a little.  The fix uses sloppy rounding to 25 bits instead of very
    sloppy rounding to 21 bits, and starts using uint64_t instead of 2
    words for bit manipulation so that rounding more bits is not much
    costly.
  - in cbrtf(), the 0.667 bound was already satisfied even with the
    inadequate increment, but change the code to almost match cbrt()
    anyway.  There is not enough spare precision in the Newton
    approximation to double the inadequate increment without exceeding
    the 0.667 bound, and no spare precision to avoid this problem as
    in cbrt().  The fix is to round using an increment of 2 smaller-ulps
    before chopping so that an increment of 1 ulp is enough.  In cbrt(),
    we essentially do the same, but move the chop point so that the
    increment of 1 is not needed.

Fixed comments to match code:
- in cbrt(), the second approximation is good to 25 bits, not quite 26 bits.
- in cbrt(), don't claim that the second approximation may be implemented
  in single precision.  Single precision cannot handle the full exponent
  range without minor but pessimal changes to renormalize, and although
  single precision is enough, 25 bit precision is now claimed and used.

Added comments about some of the magic for the error bound 4/6+epsilon.
I still don't understand why it is 4/6+ and not 6/6+ ulps.

Indent comments at the right of code more consistently.
