[non-BE][rend-non-be] Stabilize optimization of decoder side stereo panning functions to avoid non-BE between Debug and Release
Reason why this change is needed
- Decoder side stereo panning functions produce non-BE result between Debug and Release
Description of the change
- This change
LsAngleRadinto a define (as it is a constant) and also pre-calculates inverse of tangent for it to avoid optimizations.
Affected operating points
- Expected to be BE for Debug build. edit: but it is not. Max ABS Diff 1 non-BE differences due to accuracy changes.
