Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+|
+|	bindec
+|
+|	Description:
+|		Converts an input in extended precision format
+|		to bcd format.
+|
+|	Input:
+|		a0 points to the input extended precision value
+|		value in memory; d0 contains the k-factor sign-extended
+|		to 32-bits.  The input may be either normalized,
+|		unnormalized, or denormalized.
+|
+|	Output:	result in the FP_SCR1 space on the stack.
+|
+|	Saves and Modifies: D2-D7,A2,FP2
+|
+|	Algorithm:
+|
+|	A1.	Set RM and size ext;  Set SIGMA = sign of input.
+|		The k-factor is saved for use in d7. Clear the
+|		BINDEC_FLG for separating normalized/denormalized
+|		input.  If input is unnormalized or denormalized,
+|		normalize it.
+|
+|	A2.	Set X = abs(input).
+|
+|	A3.	Compute ILOG.
+|		ILOG is the log base 10 of the input value.  It is
+|		approximated by adding e + 0.f when the original
+|		value is viewed as 2^^e * 1.f in extended precision.
+|		This value is stored in d6.
+|
+|	A4.	Clr INEX bit.
+|		The operation in A3 above may have set INEX2.
+|
+|	A5.	Set ICTR = 0;
+|		ICTR is a flag used in A13.  It must be set before the
+|		loop entry A6.
+|
+|	A6.	Calculate LEN.
+|		LEN is the number of digits to be displayed.  The
+|		k-factor can dictate either the total number of digits,
+|		if it is a positive number, or the number of digits
+|		after the decimal point which are to be included as
+|		significant.  See the 68882 manual for examples.
+|		If LEN is computed to be greater than 17, set OPERR in
+|		USER_FPSR.  LEN is stored in d4.
+|
+|	A7.	Calculate SCALE.
+|		SCALE is equal to 10^ISCALE, where ISCALE is the number
+|		of decimal places needed to insure LEN integer digits
+|		in the output before conversion to bcd. LAMBDA is the
+|		sign of ISCALE, used in A9. Fp1 contains
+|		10^^(abs(ISCALE)) using a rounding mode which is a
+|		function of the original rounding mode and the signs
+|		of ISCALE and X.  A table is given in the code.
+|
+|	A8.	Clr INEX; Force RZ.
+|		The operation in A3 above may have set INEX2.
+|		RZ mode is forced for the scaling operation to insure
+|		only one rounding error.  The grs bits are collected in
+|		the INEX flag for use in A10.
+|
+|	A9.	Scale X -> Y.
+|		The mantissa is scaled to the desired number of
+|		significant digits.  The excess digits are collected
+|		in INEX2.
+|
+|	A10.	Or in INEX.
+|		If INEX is set, round error occurred.  This is
+|		compensated for by 'or-ing' in the INEX2 flag to
+|		the lsb of Y.
+|
+|	A11.	Restore original FPCR; set size ext.
+|		Perform FINT operation in the user's rounding mode.
+|		Keep the size to extended.
+|
+|	A12.	Calculate YINT = FINT(Y) according to user's rounding
+|		mode.  The FPSP routine sintd0 is used.  The output
+|		is in fp0.
+|
+|	A13.	Check for LEN digits.
+|		If the int operation results in more than LEN digits,
+|		or less than LEN -1 digits, adjust ILOG and repeat from
+|		A6.  This test occurs only on the first pass.  If the
+|		result is exactly 10^LEN, decrement ILOG and divide
+|		the mantissa by 10.
+|
+|	A14.	Convert the mantissa to bcd.
+|		The binstr routine is used to convert the LEN digit
+|		mantissa to bcd in memory.  The input to binstr is
+|		to be a fraction; i.e. (mantissa)/10^LEN and adjusted
+|		such that the decimal point is to the left of bit 63.
+|		The bcd digits are stored in the correct position in
+|		the final string area in memory.
+|
+|	A15.	Convert the exponent to bcd.
+|		As in A14 above, the exp is converted to bcd and the
+|		digits are stored in the final string.
+|		Test the length of the final exponent string.  If the
+|		length is 4, set operr.
+|
+|	A16.	Write sign bits to final string.
+|
+|	Implementation Notes:
+|
+|	The registers are used as follows:
+|
+|		d0: scratch; LEN input to binstr
+|		d1: scratch
+|		d2: upper 32-bits of mantissa for binstr
+|		d3: scratch;lower 32-bits of mantissa for binstr
+|		d4: LEN
+|		d5: LAMBDA/ICTR
+|		d6: ILOG
+|		d7: k-factor
+|		a0: ptr for original operand/final result

+|     Check d2 for excess 10 exponential value.  If not zero,
+|     the iscale value would have caused the pwrten calculation
+|     to overflow.  Only a negative iscale can cause this, so
+|     multiply by 10^(d2), which is now only allowed to be 24,
+|     with a multiply by 10^8 and 10^16, which is exact since
+|     10^24 is exact.  If the input was denormalized, we must
