An athlons, this gives a speed increase under favourable pipeline conditions of about 10% overall (larger for AXP, smaller for A64). E.g., on AXP, sinf() on uniformly distributed args in [-2Pi, 2Pi] now takes 30-56 cycles; it used to take 45-61 cycles; hardware fsin takes 65-129. diff 4ce51209523e3ebb226a036e9ad22025a501972d Mon Nov 21 05:57:12 CET 2005 Bruce Evans <bde@FreeBSD.org> Mess up the "kernel" float trig function .c files with ifdefs so that they can be #included in other .c files to give inline functions, and use them to inline the functions in most callers (not in e_lgammaf_r.c). __kernel_tanf() is too large and complicated for gcc to inline very well.
