Sam Hocevar	14a3e1f739	core: fix a bug on the PS3 version of lol_sin().	пре 14 година
Sam Hocevar	b3e2429b9e	core: avoid returning to memory when giving GCC floating point hints.	пре 14 година
Sam Hocevar	320e70d8c4	core: a few compilation fixes for non-GCC compilers.	пре 14 година
Sam Hocevar	5feadd8b6a	core: fix PS3 compilation; the lol_fdiv implementation was missing.	пре 14 година
Sam Hocevar	bf164def53	core: fix an accuracy error in the cos() part of lol_sincos().	пре 14 година
Sam Hocevar	2489233a44	core: improve tan() accuracy by tweaking higher order Taylor coefficients.	пре 14 година
Sam Hocevar	82d81256b9	core: implement accelerated lol_sincos() and lol_tan().	пре 14 година
Sam Hocevar	5be195a8b0	core: slightly reorganise Taylor series in sin() and cos().	пре 14 година
Sam Hocevar	49f9c59ff3	core: implement accelerated cos().	пре 14 година
Sam Hocevar	a65c472ffd	core: add a code shortcut for sin() on platforms that have cheap branches.	пре 14 година
Sam Hocevar	824551e4af	optim: split the Taylor series calculation into two separate values. This is at the cost of one additional multiply, but performance increases by more than 11%, because the PS3 pipeline is a lot happier now.	пре 14 година
Sam Hocevar	de496b15fe	core: remove one multiplication and one selection from the optimised version of sinf().	пре 14 година
Sam Hocevar	42b22f1163	core: minor optimisation in the x86 version of lol_sin() Instead of dividing by 2 and rounding with magic number 2^52, we round with magic number 2^53, which gives us the parity with at least one mul less.	пре 14 година
Sam Hocevar	1b33a7fcb7	core: start implementing optimised trigonometry functions for PS3 and x86.	пре 14 година
