Description Christoph Hertzberg 2019-02-15 08:35:40 UTC 
This came up in Bug 1678. 

We may optionally replace our own vector math functions and replace them by SVML, or some alternative:
https://stackoverflow.com/questions/31978592/

Pro:
 * We get immediate support for other functions like asin, erf, ...
 * Binary sizes would slightly reduce for people who use SVML anyway.
  
Maybe Contra: We could get worse performance (someone needs to check)

Isn't it a duplicate of bug 1259 ?
