* avcodec/acelp_pitch_delay: Inline small functions only used onceAndreas Rheinhardt2021-02-24
| | | | | | | | | | | | | ff_acelp_decode_8bit_to_1st_delay3, ff_acelp_decode_4bit_to_2nd_delay3 and ff_acelp_decode_5_6_bit_to_2nd_delay3 are all only used once (by g729dec) whereas ff_acelp_decode_9bit_to_1st_delay6 and ff_acelp_decode_6bit_to_2nd_delay6 are completely unused; with the possible exception of ff_acelp_decode_4bit_to_2nd_delay3, these functions are so small that inlining them is appropriate; and as long as ff_acelp_decode_4bit_to_2nd_delay3 is only called once, this is also true for it.

* all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.hGanesh Ajjanagadde2016-03-22
| | | | | | | | | | | The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanag@gmail.com>
