Often (not allways, naturally) it's enough to just rebuild with a newer compiler to leverage the new arch features.
Out of interest, what are some new things (those bringing real performance gain) from the last 6 years which a standard library needs to adapt to actively?
Edit: also note that OP made this pointed on purpose, the last release is from 2018, one year ago, not 2013...
- throwaway2048 7y agoThe standard library benefits a great deal from ASM optimized implementations of functions. New instructions get added that can speed things up significantly. the compiler will almost never automatically generate this code.
- saagarjha 7y agoThis is all true, but I’m not sure the authors of these libraries are that interested in performance.
