Description

Math library developers sometimes can trade slight loss of accuracy
for significant performance gains or slight loss of performance
for significant accuracy gains. This BoF is to review some recent
and coming libm/libgcc changes and share ideas on how to decide
where to draw the line for loss of performance vs improved accuracy
and vice-versa.
