Szabolcs Nagy 875c76c704 New generic log2f ... Similar to the new logf: double precision arithmetics and a small lookup table is used. The argument reduction step is the same as in the new logf. without wrapper on aarch64: log2f reciprocal-throughput: 2.3x faster log2f latency: 2.1x faster old worst case error: 1.72 ulp new worst case error: 0.75 ulp aarch64 .text size: -252 bytes aarch64 .rodata size: +244 bytes * math/Makefile (type-float-routines): Add e_log2f_data. * sysdeps/ieee754/flt-32/e_log2f.c: New implementation. * sysdeps/ieee754/flt-32/e_log2f_data.c: New file. * sysdeps/ieee754/flt-32/math_config.h (__log2f_data): Define. (LOG2F_TABLE_BITS, LOG2F_POLY_ORDER): Define. * sysdeps/i386/fpu/e_log2f_data.c: New file. * sysdeps/ia64/fpu/e_log2f_data.c: New file. * sysdeps/m68k/m680x0/fpu/e_log2f_data.c: New file.		2017-09-29 17:17:41 +01:00
