| D | ChangeLog-2015 | 5443 * libc/include/math.h (log2, log2f): Disable macro versions for C++,
6718 since log2 uses log(); add note about being derived instead of direct.
6916 * libc/include/math.h: Add log2 and log2f function prototypes.
9239 * libm/machine/spu/headers/log2.h: Ditto.
9330 * libm/machine/spu/headers/log2.h: Ditto.
9384 * libm/machine/spu/log2.c: Ditto.
9620 (log2, log2f, M_LOG2_E): Use _M_LOG2_E.
9629 * libc/include/math.h (_M_LOG2E): New log2 of e macro.
9630 (log2): Use _M_LOG2E instead of M_LOG2E.
