Also maybe this repository's name can be changed to ndstrim-rs or something like that? Makes it easier to distinguish and search for it explicitly. |

Hello!
I have proposed this change as FLTO is much slower in LLVM than GCC, as it doesn't use partitioning and has limited parallelism.
Thin LTO on the other hand is much faster even than GCC FLTO, and usually uses 0-2% performance, which nobody would notice in normal usage.
This halves the compile time on my machine on a release build. I know, this is seems pointless to add as the absolute time is still low (30s or so) but it shouldn't really take so long for a program of such scale.
Thanks!
