// History:
// 01/10/02 Initial version
// 01/25/02 Corrected error tag numbers
// 02/04/02 Added support of SIGN(GAMMA(x)) calculation
// 05/20/02 Cleaned up namespace and sf0 syntax
// 09/15/02 Fixed bug on the branch lgamma_negrecursion
// 10/21/02 Now it returns SIGN(GAMMA(x))=-1 for negative zero
// 02/10/03 Reordered header: .section, .global, .proc, .align
// 07/22/03 Reformatted some data tables
// 03/31/05 Reformatted delimiters between data tables
//

// Function: __libm_lgamma(double x, int* signgam, int szsigngam)
// computes the principle value of the logarithm of the GAMMA function
// of x. Signum of GAMMA(x) is stored to memory starting at the address
// specified by the signgam.

// Overview
//
// The method consists of three cases.
//
// If 512 <= x < OVERFLOW_BOUNDARY use case lgamma_pstirling;
// else if 1 < x < 512 use case lgamma_regular;
// else if -17 < x < 1 use case lgamma_negrecursion;
// else if -512 < x < -17 use case lgamma_negpoly;
// else if x < -512 use case lgamma_negstirling;
// else if x is close to negative
// roots of ln(GAMMA(x)) use case lgamma_negroots;
//
//
// Case 512 <= x < OVERFLOW_BOUNDARY
// ---------------------------------
// Here we use algorithm based on the Stirling formula:
// ln(GAMMA(x)) = ln(sqrt(2*Pi)) + (x-0.5)ln(x) - x + (W2 + W4/x^2)/x
//
// Case 1 < x < 512
// ----------------
// To calculate GAMMA(x) on this interval we use polynomial approximation
// on following intervals [0.875; 1.25), [1.25; 1.75), [1.75, 2.25),
// [2.25; 4), [2^i; 2^(i+1)), i=2..8
//
// Following variants of approximation and argument reduction are used:
// 1. [0.875; 1.25)
// ln(GAMMA(x)) ~ (x-1.0)*P17(x-1.0)
//
// 2. [1.25; 1.75)
// ln(GAMMA(x)) ~ (x-LocalMinimun)*P17(x-LocalMinimun)
//
// 3. [1.75, 2.25)
// ln(GAMMA(x)) ~ (x-2.0)*P17(x-2.0)
//
// 4. [2.25; 4)
// ln(GAMMA(x)) ~ P22(x)
//
// 5. [2^i; 2^(i+1)), i=2..8
// ln(GAMMA(x)) ~ P22((x-2^i)/2^i)
//
// Case -17 < x < 1
// ----------------
// Here we use the recursive formula:
// ln(GAMMA(x)) = ln(GAMMA(x+1)) - ln(x)
//
// Using this formula we reduce argument to base interval [1.0; 2.0]
//
// Case -512 < x < -17
// --------------------
// Here we use the formula:
// ln(GAMMA(-x)) = ln(Pi/(x*GAMMA(x)*sin(Pi*x))) =
// = -ln(x) - ln((GAMMA(x)) - ln(sin(Pi*r)/(Pi*r)) - ln(|r|)
// where r = x - rounded_to_nearest(x), i.e |r| <= 0.5 and
// ln(sin(Pi*r)/(Pi*r)) is approximated by 14-degree polynomial of r^2
//
//
// Case x < -512
// -------------
// Here we use algorithm based on the Stirling formula:
// ln(GAMMA(-x)) = -ln(sqrt(2*Pi)) + (-x-0.5)ln(x) + x - (W2 + W4/x^2)/x -
// - ln(sin(Pi*r)/(Pi*r)) - ln(|r|)
// where r = x - rounded_to_nearest(x).
//
// Neighbourhoods of negative roots
// --------------------------------
// Here we use polynomial approximation
// ln(GAMMA(x-x0)) = ln(GAMMA(x0)) + (x-x0)*P14(x-x0),
// where x0 is a root of ln(GAMMA(x)) rounded to nearest double
// precision number.
