and so it goes, on and on and on. We might either do it now and iron out the kinks
during 1.5 or do it very early in 1.6.

@vchuravy vchuravy force-pushed the vc/upgrade_llvm_10 branch 2 times, most recently from 174ecd2 to 8ae92cc Compare March 31, 2020 01:17

This might be the first upgrade where Windows passes at the first attempt...

@Keno can I bother you with updating the GCAnalyzer?

What’s the current thinking on when this might merge?

Just wondering, regarding llvm support for new arm cpus related to #36485, a few of which were added in 10.

I guess it’d need performance benchmarking given the feared 10% that hit rust https://nikic.github.io/2020/05/10/Make-LLVM-fast-again.html

My current thinking is to wait of 10.0.1 or 11, but yes additional performance benchmarking of the compile time would be good.

Also #35460 needs to be fixed first. @ianshmean if you want to try your hand at writing an LLVM patch ;)

I'm happy to take a look in some of my fun time. Can't promise much though..

@vchuravy would you mind rebasing this?

Well, I assume they are not "competing".....

Just that I felt like I've fixed a more complex aarch64 relocatioin before, and it's definitely not either R_AARCH64_ABS32 or R_AARCH64_ABS64.

Is there an LLVM IR that triggers this? That'll make testing significantly easier.

edit: ah, found the ppc one in #35460

Is there a patch for this (#35460) already? I finally have a (actually 2) working aarch64 systems again so if no one is working on it I can.

No patch that I am aware off.

I did some timings on my laptop (so take it with a grain of salt)

TLDR

Would LLVM 11 be an option for Julia 1.6? RC-2 is out now, with 11-final planned for August 26th.
If so, it'd be worth benchmarking as well. There's been a lot of recent work on improving LLVM's speed, mainly for Rust's sake:
https://nikic.github.io/2020/05/10/Make-LLVM-fast-again.html
https://blog.mozilla.org/nnethercote/2020/08/05/how-to-speed-up-the-rust-compiler-some-more-in-2020/
Would be interesting to benchmark and see if it helps us, too.

I believe LLVM 11 also includes this: https://reviews.llvm.org/D75016
I'd like to at least have that patch in Julia 1.6. I'll look into how to apply it if we won't ship with Julia LLVM 11 (i.e., looking at Valentin's and Yuyichao's PRs to see how it's done).
That patch should allow LoopVectorization to stop using asm call for vfmadd231p(d/s), and just use @llvm.fmuladd instead.

BTW, not particularly relevant to this issue, but the AVX-512 down-clocking problem has been almost complete solved as of Ice Lake: https://travisdowns.github.io/blog/2020/08/19/icl-avx512-freq.html

Instructions: scalar/light128 bit - heavy 256 bit - heavy 512 bit
My cascadelake 1 core: 4.6 - 4.3 - 4.1
My cascadelake all-core: 4.6 - 4.3 - 4.1
Ice Lake i5-1035G4 1 core: 3.7 - 3.7 - 3.6
Ice Lake i5-1035G4 4 core: 3.3 - 3.3 - 3.3
There are some other problems where LLVM generates bad AVX-512 code where 256 bit vectors would be faster than 512 bit, even at the same clock speed.

I haven't found out how to use JULIA_LLVM_ARGS to actually change the preferred vector width, so I can't run benchmarks without also using different LLVM versions. LLVM's args are different from Clang's (where it would be -mprefer-default-vector-width=$BITS).

I assume you mean -mprefer-vector-width=.

It's not an LLVM command line option but a (global and per-function) target property. Add prefer-256-bit to the cpu specification should work, i.e. julia -C "native,prefer-256-bit".

@chriselrod I was thinking the same. Getting to LLVM 11 in 1.6 seems like a good idea on the face of it. 10 does seem to be the ugly duckling and the work on speed since does seem positive, but probably still a good idea to work through 10 to get to 11?

There's also some newer arm chip support in LLVM 11 such as nvidia Carmel that would be nice to get into the next LTS.

10 does seem to be the ugly duckling

It may be the ugly duckling, but I did notice some improvements in several LoopVectorization examples, where integer/indexing code was handled better by LLVM 10 than by LLVM <=9. So there're some definite improvements (that probably apply to other examples as well?).

A simple example of where 256-bit performs much better than 512-bit:

julia> function trmv!(y, A, x)
           fill!(y, 0)
           @inbounds for n ∈ axes(A,2)
               @simd for m ∈ 1:n
                   y[m] += A[m,n] * x[n]
               end
           end
       end
trmv! (generic function with 1 method)

julia> M = 64; C = rand(M, M); x = rand(M); y = similar(x);

julia> @benchmark trmv!($y, $C, $x)
BenchmarkTools.Trial:
  memory estimate:  0 bytes
  allocs estimate:  0
  --------------
  minimum time:     825.942 ns (0.00% GC)
  median time:      830.907 ns (0.00% GC)
  mean time:        838.359 ns (0.00% GC)
  maximum time:     1.315 μs (0.00% GC)
  --------------
  samples:          10000
  evals/sample:     86

Versus starting with -C "native,prefer-256-bit":

julia> function trmv!(y, A, x)
           fill!(y, 0)
           @inbounds for n ∈ axes(A,2)
               @simd for m ∈ 1:n
                   y[m] += A[m,n] * x[n]
               end
           end
       end
trmv! (generic function with 1 method)

julia> M = 64; C = rand(M, M); x = rand(M); y = similar(x);

julia> @benchmark trmv!($y, $C, $x)
BenchmarkTools.Trial:
  memory estimate:  0 bytes
  allocs estimate:  0
  --------------
  minimum time:     508.031 ns (0.00% GC)
  median time:      509.016 ns (0.00% GC)
  mean time:        509.541 ns (0.00% GC)
  maximum time:     668.363 ns (0.00% GC)
  --------------
  samples:          10000
  evals/sample:     193

FWIW, replacing @simd with @avx on the inner loop yields 350ns with 512 bit vectors, which is why I emphasize that this is a problem with LLVM, not a problem with wide vectors.
@avx doesn't work on the outer loop yet because the loop is triangular, but I'll find the time to do this some day.

Note that this is LLVM 10.0.1 so lots of fixes might already been backported. Going to LLVM 11 is feasible, but higher risk and might involve more work from our side to side out regressions.

If you really want to see LLVM 11 for 1.6 I would appreciate help with that. Getting an WIP on Yggdrasil for rc2 would be the first step, as well as looking at the patch list. Currently I do these upgrades when I am plagued by insomnia.

I've read a lot of LLVM IR, but that's very different from being familiar with LLVM itself.

What's the procedure for these upgrades, how I would I start? Which patch list? Julia's list of LLVM patches, to see which are no longer needed in LLVM 11?
