Upgrade LLVM to trunk, still version 8 #55835

alexcrichton · 2018-11-09T23:07:58Z

This commit upgrades the LLVM/LLD/compiler-rt submodules used to the current trunk versions in upstream. Some activity has happened on the wasm SIMD side of things as well as LLD which we'd like to pick up!

Well by golly gee those are some good numbers, surprising!

nikic · 2018-11-11T11:09:30Z

Those are some very nice results!

At least the improvements on inflate are primarilty due to https://reviews.llvm.org/D53245 -- this used to spend ~25% of the time applying DomTree updates in JumpThreading and now no longer does.

alexcrichton · 2018-11-11T17:21:38Z

Rebased! I've done some (hopefully) thorough testing locally and I've discovered... amazingly zero regressions!

Should be ready to go!

vext01 · 2018-11-12T10:12:14Z

Hi Alex,

Thanks for dealing with this. It should have really been me doing the work, since I spawned the discussion!

I was wondering: do you have a way to check for performance regressions?

Thanks

vext01 · 2018-11-12T10:43:36Z

Ah yes, I see you have a benchmarking bot :) Neat.

alexcrichton · 2018-11-12T15:11:01Z

@vext01 oh no worries! I ended up wanting to do it for unrelated reasons anyway and figured I could help bootstrap the process at least, I didn't expect it to go so smoothly, but I'm sure bors will have a thing or two to say about that

📌 Commit 28d73341204480bbbd82b189ee84f839bf8dd208 has been approved by nikomatsakis

Our mangling scheme is not C++'s, so tell LLD to not demangle anything so we can handle Rust-specific demangling ourselves.

This should handle recent symbol visibility changes happening, although we'll likely want to tweak this in the future!

alexcrichton · 2018-11-26T04:28:46Z

Oops, forgot to disable LLDB

⌛ Testing commit 7215963 with merge 6bfb46e...

Upgrade LLVM to trunk, still version 8 This commit upgrades the LLVM/LLD/compiler-rt submodules used to the current trunk versions in upstream. Some activity has happened on the wasm SIMD side of things as well as LLD which we'd like to pick up!

bors · 2018-11-26T15:12:01Z

☀️ Test successful - status-appveyor, status-travis
Approved by: nikomatsakis
Pushing 6bfb46e to master...

nnethercote · 2018-11-29T21:19:47Z

Final perf results from the landing are here. Very nice results, mostly on opt builds.

Upgrade to LLVM trunk

7be0b23

Handle some renamed ThinLTO functions

ae5b350

Make Rustc build with LLVM trunk.

a43a7a0

Conditionally compile in only the extra argument.

bf01bcb

wasm: Pass --no-demangle to LLD

c86b152

Our mangling scheme is not C++'s, so tell LLD to not demangle anything so we can handle Rust-specific demangling ourselves.

Pass --export-dynamic to LLD for wasm

cc9c91d

This should handle recent symbol visibility changes happening, although we'll likely want to tweak this in the future!

Temporarily disable LLDB
