https://bugs.freedesktop.org/show_bug.cgi?id=27901 --- Comment #1 from Conn Clark <conn.o.clark@xxxxxxxxx> 2010-05-17 15:10:30 PDT --- A proper fix would be to fix the r700_assembler.c code so that it generates code to translate the radians input to a corresponding value between PI and -PI before passing it to the SIN or COS instructions. I *think* that this could be achieved through the following r600 instructions inst count unit opcode DEST SRC0, SRC1, SRC3 0 x: MUL tmp.x, ang, 1/(2.0 * pi) 1 x: FRACT tmp.x, tmp.x 2 x: ADD tmp.x, tmp.x, -0.5F y: MULADD tmp.y, tmp.x, (2.0 * pi), -(2.0 * pi) z: MUL tmp.z, tmp.x, (2.0 * pi) 3 x: CMOVEGT tmp.x, tmp.x, tmp.y, tmp.z 4 t: SIN or COS dest, tmp.x Unfortunately I can't quite figure out how to do it in the code yet to try and see. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
