Pale Moon x86-64 AVX/AVX2

Unread post by Nuck-TH » 2022-02-07, 15:50

Amended Thu Dec 8, 2022 at 15:39 UTC.

As allowed by Moonchild, i finally decided to post my AVX/AVX2 builds of Pale Moon.

Build VM is latest VirtualBox with:
  • Pale Moon release branch
  • Windows 10 LTSC and VS2022/SDK and tools as specified on dev site with following .mozconfig:

    Code: Select all

    # Tell the build system if we're building 64-bit.
    # Set this to `BUILD_64=1` for 64-bit, leave as-is for 32-bit
    BUILD_64=1
    
    # Processor architecture specific build options
    if [ -n "$BUILD_64" ]; then
    BUILD_ARCH=x64
    ac_add_options --target=x86_64-pc-mingw32
    ac_add_options --host=x86_64-pc-mingw32

    Both GTK2 and GTK3 builds are done.
Casual usage of AVX and AVX2 Windows builds on both intel and AMD processors shows no apparent instability, but be aware that it is still possible as no extensive testing was ever done. At this point it seems like i can conclude that there is no additional issues so far.
It is unclear if this build provides any performance benefits(allegedly it does, but no side-by-side comparison was done), so your mileage may vary.

I will try to build new releases ASAP, but may lag a day or two. Usually i do wait for shakedown to build straight up point releases avoiding unnecessary work.

Carefully take note of the following:
  • While branded with official branding, this build has non-official settings(usage of AVX/AVX2 optimizations), so before getting official support you should reproduce problem on official build with clean profile.
  • From 31.0.0-Windows and 31.1.0-Linux onward builds have auto updater.
  • WARNING: I have no full-fledged linux installation, so Linux builds are "tested" to the extent that they run on build system. Please use them with caution until at least handful of users report them stable enough.While testing from my part isn't changed, there are no complains so far.
  • Using any of this build on CPU that doesn't support corresponding instruction set will cause instability and crashes. Google your CPU model or use software like CPU-Z to check.
  • Installers are not signed, but GPG detached signatures are provided for both archives and installers.

If you understood information and warnings above, then latest builds would be on contributed builds FTP:
Windows: FTP HTTP
Linux: FTP HTTP

To make portable version paste palemoon folder from 7z archive into bin folder inside unpacked official portable version, but note that usage of not yet universally widespread instruction sets will limit its portability.

This is simply amazing. Tried AVX2 Build on windows 7 ryzen 5 3500U. Sublime performance.

Build of version 29.4.5 is in the same Yandex.Disk folder, now with x86 builds and detached PGP signatures instead of checksums.

Version 29.4.6 is up. Please update, as it contains security patches.
Also note that i do x86 builds already for some time, so if your system is not 64-bit - you can benefit from AVX(2) too.

Um... AVX/AVX2 is a thing for 64-bit CPUs only. 32-bit processors don't have AVX extensions. The earliest processor that had AVX is the Intel Sandy Bridge (2011) and those were x86_64 only. Same on AMD's side. Now, I'm not sure if running a 32-bit OS on a 64-bit CPU will still give you access to the AVX instructions or not. I guess you might but it's a strange setup in that case.

I was going to post saying that I don't think there is much of a reason for people to use an AVX capable CPU with x86 Windows (except retro 2000/XP builds on modern hardware), but I backed out because this forum is very unpredictable.

I run 32-bit antiX Linux on some of my older 64-bit systems because the memory usage is nearly cut in half while the performance remains about the same. I'd like to try AVX/AVX2 Pale Moon and see if it would run and if it would be fast, but @Nuck-TH hasn't made any Linux versions from what I could see.

I meant 32-bit OS on CPUs with AVX(2) support.
A bit of searching shows that using AVX while running 32-bit OS is allegedly possible, but some instructions(apparently that operate 64-bit operands or something like that) are not available. Bad thing that apparently it fails silently without illegal instruction fault. So compiler should take this into account, but places with hand-optimised assembly may cause issues if no checks are made.

Why should we today use an 32 Bit OS (i386 etc.) on a CPU with amd64 instructions?
I can't see a reason. I only use i686 on CPUs without amd64/EM64T.

My guess would be lower RAM usage and specific driver availability, for systems that still need these.

I really advise against publishing these x86 builds then. Our platform -has- a lot of hand-written assembly in it, including AVX stuff, in various components that may fail as a result. While I am fairly certain it's all guarded with x64 checks, I'm not 100% sure.
The MSVC compiler doesn't offer AVX options in x86 cross-compile mode for a reason, too, so I don't know in what other way (except the potentially broken way) you'd be optimizing the 32-bit ones, and it would in effect be just like the mainline binaries for x86 aside from potential problems :P People should just be using the mainline ones instead in that case as there won't be a positive difference.

Taken down then. Better to keep away from very possible potential issues.
Less build time for me then, yay. Maybe i would consider linux builds, but that would be completely untested, as i don't run(yet?) linux except for occasional development or building stuff. It also bugs me that i probably won't be able to provide packages for package managers, because it is very convenient way of installing and updating software...
So much for thread renaming %)

I wouldn't be concerned about the different package managers if I were you, the tarball binaries work great and are very convenient.

I'd better bother with good old native package managers than figure out and use solution with fair share of substantial issues.
And i'm not even starting on that it is likely not possible due to licensing issues that were previously discussed on the forum.

If you can get it on each major distros package manager, apt, dnf, pacman, go ahead. However, if you're not going to do that or can't, just go with a flatpak.

Can't be done due to licensing issues as already pointed out.
