// else if -(i+1) < x < -i, i = 0...43 use case tgamma_negatives;
//
// Case 2 <= x < OVERFLOW_BOUNDARY
// -------------------------------
// Here we use algorithm based on the recursive formula
// GAMMA(x+1) = x*GAMMA(x). For that we subdivide interval
// [2; OVERFLOW_BOUNDARY] into intervals [8*n; 8*(n+1)] and
// approximate GAMMA(x) by polynomial of 22th degree on each
// [8*n; 8*n+1], recursive formula is used to expand GAMMA(x)
// to [8*n; 8*n+1]. In other words we need to find n, i and r
// such that x = 8 * n + i + r where n and i are integer numbers
// and r is fractional part of x. So GAMMA(x) = GAMMA(8*n+i+r) =
// = (x-1)*(x-2)*...*(x-i)*GAMMA(x-i) =
// = (x-1)*(x-2)*...*(x-i)*GAMMA(8*n+r) ~
// ~ (x-1)*(x-2)*...*(x-i)*P12n(r).
//
// Step 1: Reduction
// -----------------
// N = [x] with truncate
// r = x - N, note 0 <= r < 1

GLOBAL_LIBM_END(tgammaf)
Use libm_alias_float for ia64. Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes ia64 libm function implementations use libm_alias_float to define function aliases. The same approach is followed as with the corresponding long double and double patches: the ia64-specific macros are left unchanged, with calls to libm_alias_float_other being added in most cases and libm_alias_float itself being used in only a few places. Tested with build-many-glibcs.py for ia64-linux-gnu that installed stripped shared libraries are unchanged by the patch. * sysdeps/ia64/fpu/libm-symbols.h: Include <libm-alias-float.h>. * sysdeps/ia64/fpu/e_acosf.S (acosf): Use libm_alias_float_other. * sysdeps/ia64/fpu/e_acoshf.S (acoshf): Likewise. * sysdeps/ia64/fpu/e_asinf.S (asinf): Likewise. * sysdeps/ia64/fpu/e_atan2f.S (atan2f): Likewise. * sysdeps/ia64/fpu/e_atanhf.S (atanhf): Likewise. * sysdeps/ia64/fpu/e_coshf.S (coshf): Likewise. * sysdeps/ia64/fpu/e_exp10f.S (exp10f): Likewise. * sysdeps/ia64/fpu/e_exp2f.S (exp2f): Likewise. * sysdeps/ia64/fpu/e_expf.S (expf): Likewise. * sysdeps/ia64/fpu/e_fmodf.S (fmodf): Likewise. * sysdeps/ia64/fpu/e_hypotf.S (hypotf): Likewise. * sysdeps/ia64/fpu/e_lgammaf_r.c (lgammaf_r): Define using libm_alias_float_r. * sysdeps/ia64/fpu/e_log2f.S (log2f): Use libm_alias_float_other. * sysdeps/ia64/fpu/e_logf.S (log10f): Likewise.
