| H A D | s_tanf.c | diff 152647 Mon Nov 21 04:57:12 MST 2005 bde 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. 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. |
