| H A D | s_cos.c | diff 176385 Mon Feb 18 14:02:12 MST 2008 bde Inline __ieee754__rem_pio2(). With gcc4-2, this gives an average optimization of about 10% for cos(x), sin(x) and tan(x) on |x| < 2**19*pi/2. We didn't do this before because __ieee754__rem_pio2() is too large and complicated for gcc-3.3 to inline very well. We don't do this for float precision because it interferes with optimization of the usual (?) case (|x| < 9pi/4) which is manually inlined for float precision only. This has some rough edges: - some static data is duplicated unnecessarily. There isn't much after the recent move of large tables to k_rem_pio2.c, and some static data is duplicated to good affect (all the data static const, so that the compiler can evaluate expressions like 2*pio2 at compile time and generate even more static data for the constant for this). - extern inline is used (for the same reason as in previous inlining of k_cosf.c etc.), but C99 apparently doesn't allow extern inline functions with static data, and gcc will eventually warn about this. Convert to __FBSDID(). Indent __ieee754_rem_pio2()'s declaration consistently (its style was made inconsistent with fdlibm a while ago, so complete this). Fix __ieee754_rem_pio2()'s return type to match its prototype. Someone changed too many ints to int32_t's when fixing the assumption that all ints are int32_t's. |
