Consider using incremental linking with msvc #37543

Open retep998 opened 7 years ago

retep998 commented 7 years ago

Incremental linking will allow for significantly faster link times, at the cost of binary size.

  1. Don't delete the output artifacts. The .ilk and .exe or .dll must remain from the previous run.
  2. Don't pass /OPT to the linker or any other flag that is mutually exclusive with incremental linking.
  3. Pass /INCREMENTAL to the linker.
  4. The set of files passed to the linker must remain the same. If the codegen unit object files change names, then it will do a full link.

Alternatively, provide LLD as a stable alternative to link.exe so users can benefit from faster links when they don't need any special features of link.exe.

This issue has been opened because the building times with rust-qt are quite high. Here's a simple example:

Specs

But the main problem is not the crazy times when doing a cold build on the qt crates but the crazy times it takes to build the simplest qt example, for instance, let's consider this dummy example:

extern crate qt_widgets;

use qt_widgets::application::Application;
use qt_widgets::push_button::PushButton;
use qt_widgets::cpp_utils::*;
use qt_widgets::qt_core::string::String;
use qt_widgets::libc::{c_char, c_int};

fn to_qt_string<S: AsRef<str>>(s: S) -> String {
  let slice = s.as_ref().as_bytes();
  String::from_utf8((slice.as_ptr() as *const c_char, slice.len() as c_int, AsStruct))
}

fn from_qt_string(string: &String) -> std::string::String {
  let buf = string.to_utf8(AsStruct);
  unsafe {
    let bytes = std::slice::from_raw_parts(buf.const_data() as *const u8, buf.count(()) as usize);
    std::str::from_utf8_unchecked(bytes).to_string()
  }
}

fn main() {
  let _app = Application::new((&mut 0i32, &mut (&mut 0i8 as *mut i8) as *mut *mut i8, AsBox));
  let mut btn = PushButton::new((&to_qt_string("first_button"), AsBox));
  let mut btn2 = PushButton::new((&to_qt_string("second_button"), AsBox));
  let text = from_qt_string(&btn.text(AsStruct));
  let text2 = from_qt_string(&btn2.text(AsStruct));
  btn.show();
  btn2.show();
  let ret = Application::exec();
}

If i build and then touch this file (no editing at all, just saving/changing timestamp) and I run cargo rustc -- -Z time-passes the backlog will be:

And that's the main problem, you can't iterate with these crazy times for a trivial example. Hopefully all this info will help to improve rust. Amazing package manager, cool language syntax and features... but... if building times are that crazy I don't see which benefits would bring me to stay away from c++/qt or python/pyqt.

I always envisioned that we would use any incremental linking functionality available when also compiling incrementally. That is certainly a good idea. Always using it also for regular builds is probably not a good idea because of binary sizes.

Show we expose incremental linking as a separate -C flag? Cargo.toml could have an incremental profile key that could be set to link-only?

The Gold linker also allows for incremental linking.

cc @rust-lang/tools @rust-lang/compiler

alexcrichton commented 7 years ago

Seems plausible to me, I'd be fine just defaulting to using this with -C incremental=foo once that's stabilized.

jasonwilliams commented 6 years ago

hey @alexcrichton Whats the update on this? Servo takes an awful long time to compile on Windows and i think its related to the lack of this. Is there anything i can do to push this forward?

alexcrichton commented 6 years ago

Not much has happened on this AFAIK, but we can still implement it at any time!

Win 8.1, rustc 1.26.0-nightly (2789b067d 2018-03-06)

The build before that one (also after just touching a src file) took 42 seconds. This is a lot, especially considering that cargo check in sublime and cargo watch -x run can't run in parallel, so when I save a file in Sublime, they always have to run both, and the order is random, whoever gets the lock first. And 80% of the time, cargo watch -x run gets the lock first and then I will only get the inline errors in sublime after both have finished..

So, please at least allow running check and build/run in parallel, not exclusively!

So, please at least allow running check and build/run in parallel, not exclusively!

That sounds unrelated to this issue, consider opening a new one (in the cargo repository).

@Boscop, are these timings with incremental compilation enabled?

jasonwilliams commented 6 years ago

Don't delete the output artifacts. The .ilk and .exe or .dll must remain from the previous run.

@retep998 @alexcrichton are these all generated in the target folder?

alexcrichton commented 6 years ago

@Jayflux I'm not sure, but the incremental folder can be assumed to be preserved and so intermediate artifacts can be stored somewhere in there.

jasonwilliams commented 6 years ago

Don't pass /OPT to the linker or any other flag that is mutually exclusive with incremental linking.

Unless ive got this wrong, this bit of work has already been done

michaelwoerister commented 6 years ago

The incremental folder stores object files, but before linking they are copied to where the compiler would otherwise generate them. The final executable/dll is not touched by incremental compilation. I don't know if we have an explicit step in the compiler that would delete it before invoking the linker.

@michaelwoerister Incremental is enabled by default, right? So then it must be enabled.

michaelwoerister commented 6 years ago

@Boscop It's only the default for debug builds and cargo check. The output above says Finished dev [optimized + debuginfo] target(s), so I'm wondering. On the other hand, it shows a very high number of object files being generated, which usually indicates incremental compilation. If you run cargo with --verbose, then we'd know for sure.

If this is with incremental compilation enabled then this is some kind of bug or at least a severe corner case that we should investigate. Just touching a file is usually the best case scenario and no object files should have to be recompiled.

Boscop commented 6 years ago

I have this in my Cargo.toml:

[profile.dev]
incremental = true
opt-level = 1

Because otherwise it was too slow (for real-time audio) in debug mode and using too much cpu..

Is there a way I can keep the opt-level but make the compilation faster?

michaelwoerister commented 6 years ago

@Boscop This should not be re-compiling so much with incremental compilation after just touching a file. Could you open an issue about this, if possible with a way to reproduce?

I don't know of a way to make this faster. As long as incremental compilation doesn't work for your project, you should turn it off and use codegen-units = 4 (or however many CPU cores you have) instead.

jasonwilliams commented 6 years ago

What is there to do in this issue? Are the OP instructions still valid?

jasonwilliams commented 6 years ago

The long compilation times are still a problem

jasonwilliams commented 6 years ago

On Servo my build is much faster after i set my local cargo to use lld-link.exe from LLVM. Downloaded from https://llvm.org/builds/ then 

[target.x86_64-pc-windows-msvc]
linker = "lld-link.exe"
Boscop commented 6 years ago

@jasonwilliams Did you download the win32 or win64 version?

jasonwilliams commented 6 years ago

@Boscop i used the win32 version, any particular reason you ask? Looking again at the LLVM website i see there is a 64bit version, i may try that

@michaelwoerister how can i reproduce this isssue?

mmgeorge commented 1 month ago

Any plans to still consider supporting this? Linking is still a pain point on incremental builds (often takes almost all the time), & it would be great if we could take advantage of this on windows. Trying to proxy project deps through a dylib is fairly cumbersome, as it quickly falls into you needing to pass -Cprefer-dynamic & then patch deps to other dylib proxies.

I tried passing -Clink-args=/INCREMENTAL, but I'm not seeing any .ilk files in the build directory. (-Clink-args=/DEBUG:NONE does however help quite a bit by disabling the .pbds)

bjorn3 commented 1 month ago

Is lld-link.exe fast enough? My understanding is that modern (almost) fully parallel linkers like lld are often just as fast as incremental linking with old school (mostly) non-parallel linkers like link.exe.

mmgeorge commented 1 month ago

lld definitely seems faster than link. Though maybe the gap between them has been brought down [2019, 2021]? Here's some very rough numbers using a pretty contrived example that pulls in a bunch of deps. In my project I'm building a dylib that I then hot reload in my main program, so I'm seeing now that linking the dylib (along with -Zshare-generics=n -Cprefer-dynamic), appears to increase link times quite a bit vs a fully static lib:

Machine: CPU=AMD 7700X, RAM=32GB 4400Mhz DDR5, SSD=RefS-formatted Samsung 990 Pro
With lib as dylib, imported by main (for hot-reloading):
linker		 full /DEBUG:NONE
link.exe 6.70 4.03
rust-lld 5.05 2.74
With static lib: linker full
link.exe 4.0
rust-lld 3.78
Machine: CPU=i7-7700HQ, RAM=16GB 2400MHz DDR4, SSD=Samsung MZVLV256HCHP With lib as dylib, imported by main (for hot-reloading): linker full /DEBUG:NONE
link.exe 15.34 10.31
rust-lld 12.74 7

I'm not sure how parallel lld is, eyeballing the task manager it only looked like 3 threads were getting used (vs what looked like 2 for link?), admittedly not very scientific on my end 😆. Curious on how mold would perform here.

It's a good point that it warrants seeing if link.exe + /INCREMENTAL is actually faster than lld. Looking online, I'm not really even seeing much info concerning link.exe full vs incremental other than https://devtalk.blender.org/t/speed-up-c-compilation/30508/14

Disk Full Hot Full Cold Incremental Hot Incremental Cold
HDD 27.375 218.187 7.688 164.324
SDD 24.381 56.774 7.627 11.887

If we also see a 3x improvement then that would be pretty great for incremental builds. On the other hand, it looks like incremental linking can also run into the problems reported in https://github.com/godotengine/godot/issues/77968
