Heavy usage of traits & generics causes incredibly slow compile times & code bloat #78925

Open Kixiron opened 4 years ago

Kixiron commented 4 years ago

differential-datalog makes heavy use of timely-dataflow and differential-dataflow. When using this library, compile times are excessively slow (even when no changes are made to the library itself), taking up to 10 minutes to build in debug mode and much longer in release mode.

Running llvm-lines reveals a lot of code being generated, with ptr::drop_in_place() leading the bunch

  Lines           Copies        Function name
  -----           ------        -------------

    ...

Full output

Running cargo-bloat shows that the crate takes up almost 17mb in debug mode and a still sizeable 2mb in release mode

@Kixiron could you run -Z self-profile on the crate and see if anything sticks out as taking much longer than the rest? https://github.com/rust-lang/measureme/blob/master/summarize/Readme.md

Wow, that's almost completely LLVM.

Have you tried turning off LTO, or using ThinLTO instead?

Kixiron commented 4 years ago

No matter the LTO settings it's still a long time, it is less though

jyn514 commented 4 years ago

@Kixiron in debug mode, -C no-prepopulate-passes brought this down from 31 to 24 seconds for me. It doesn't work for release mode though (or at least, the fix is worse than the cure: the flag means 'do absolutely no optimizations not even the easy ones').

jyn514 commented 4 years ago

Your main issue is that the compiler is just doing a staggering amount of work; -Z print-mono-items shows me over 100000 items being defined and compiled, even more than rustc_middle (https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Making.20rustc_middle.20faster.20to.20compile/near/212154272).
