//==============================================================
|
||
|
|
// 2/02/00 Initial revision
|
||
|
|
// 4/02/00 Unwind support added.
|
||
|
|
// 5/10/00 Improved speed with new algorithm.
|
||
|
|
// 8/08/00 Improved speed by avoiding SIR flush.
|
||
|
|
// 8/17/00 Changed predicate register macro-usage to direct predicate
|
||
|
|
// names due to an assembler bug.
|
||
|
|
// 8/30/00 Put sin_of_r before sin_tbl_S_cos_of_r to gain a cycle
