What does the humongous /usr/lib/libLLVM.so.3 do?
libLLVM and slackware-current
I have been building slacko-current based on slackware-current - all is working pretty good except I have the unsatisfied dependencies shown below.
The slackware-current llvm package is a humongous 54MB so I really don't want to have to include it if at all possible in a 250MB iso.....it's absence doesn't seem to be causing many problems except 01micko reported:

Anybody got any suggestions? - like maybe making a stub libLLVM which satisfies the dependencies in the smallest way possible?GLX isn't working.. Aha! here's why..Code: Select all

Main version used daily: LxPupSc; Assembler of UPups, ScPup & ScPup64, LxPup, LxPupSc & LxPupSc64
If you check out slackware-current changelog, on November 24 LLVM was rebuilt with clang compiler - which makes sense.
More info on LLVM
The Xorg drivers don't seem to have been built with clang (well they could be but I don't see it in the changelog) however from the same day MESA is rebuilt. Maybe Patrick will rebuild Xorg and drivers linked against LLVM (with clang compiler) before release. Hard to say for sure but it would make sense and make those packages smaller.
This explains why GLX fails.
If you crack open the LLVM package you see that most of the bloat is executables in /usr/bin. To my way of thinking, these will be unnecessary for our purposes so can be discarded in a package template in woof (I'll attach one). The actual libLLVM.so.3.7.0 is ~33M. All the lib*.a and lib*.la will go to devx removing more bloat. I'm guessing we can get compressed size on disk to around 10 to 15MB (a real guess!).
Perhaps an optional 'clang' template could be made putting clang and friends on the devx. I'll think about that when I migrate to -current.
Cheers!
------------------------------------------------------------------------------------
Usage for the packages-templates:
extract the attached package in the woof tree
add the following to your specs file
yes|llvm-cut|llvm|exe,dev,doc,nls
(I have no idea if more deps are needed. Before you do this just add llvm to your running setup and reboot. see if GLX works and check /var/log/xorg.0.log for errors)
run ./1download an llvm will be downloaded
run ./2createpackages and choose llvm-cut
Check that you have a sane llvm-cut in packages-slacko
build the iso
---------------------------------------------------------------------------------------
UPDATE:
from the slackware-current LLVM package I ran the doinst.sh (to create the symlinks) , deleted everything except /usr/lib (which is what the template does) deleted all the *.la, *.a libs (which go to devx) and repackaged as llvm-3.7.0-i586.pet, weighing in at 12MB (xz compressed). Size on disk is ~57MB.
I then booted into my slackocurrent install and installed the pet.
Results are good:

Build using cmake and clang. This results in a smaller package size, fixes
compiler-rt, and changes the shared library name from libLLVM-3.7.so to
libLLVM.so.3.7.0 (which requires recompiling any binaries linked to libLLVM).

Been reading this thread with interest.
I noted...
1.) Not in Slacko5.7 or my derivitive AtomicPup.
2.) PeeBee's list does not include any Intel vid driver. Tungsten = no, Gallium = yes
It appears all other vid drivers access it including swrast.
EDIT: Wikipedia- LLVM Features

Hi 8gee.
I've been running xenialPup-706 without the LLVM library for 2 months now
and there is no difference in visual performance on this computer.
Another month without problems and I'll print myself a T-shirt that reads:
"LLVM is a hoax."![Laughing :lol:](./images/smilies/icon_lol.gif)
BFN.

Uggg. Llvm is so frustrating. It has no simple way of removing support for architectures that it supports, but are completely useless for 99% of people. For example most x86_64 linux users don't need to build Qualcomm's hexagon or Microsoft windows binaries much less jit build them. On top of that it is written in c++ vs c, so compilers have a more difficult time eliminating unused cruft - thus the gratuitous amount of relatively large binaries. They tried to mitigate this to some extent by optionally combining most of the little static libraries into a single shared library, but not all binaries or dependent projects can take advantage of the shared library version of llvm either due to lack of maintenance (internal binaries) or for performance reasons (Mesa) It _could_ be made smaller and still function by modifying the build process to exclude unnecessary *.a libs from the *.so and even further by excluding some *.o files from the *.o files. IIRC ttuuxxx did something similar for an older version of Firefox, but most people won't have the skill set to do it and of those that do, most won't have the patience. I lack the patience to do anything other than a 1 time hack job like my mostly static build of midori, but the sources are poorly organized/named (not as bad as Mozilla, but bad) so it's difficult to pinpoint which objects and libraries can be omitted and, since it is c++, more difficult to find unnecessary references to them in the sources.
TLDR it's possible to make it smaller but not easy... a good GSOC project.
As for Mesa, the primary user, it can be built without llvm and then the drivers that absolutely need llvm can be built against a static PIC build of llvm (so only those drivers absorb the cost, but only the minimum cost); however this is a complicated arrangement that most automated build systems can't support.

The latest EasyOS, 0.9.5, doesn't have llvm.
This distro is built with packages compiled from source in 'oe-qky-src', my fork of OpenEmbedded.
The only thing that I am missing out on is support for some video hardware, affecting a very small minority of users I think.
For the record:

Morning musher0,
A quiet Sunday morning so just for hoots over coffee, working on my fairly modified upupbb 18.05 +10, I removed the llvm libs and samba (a pretty thorough but probably not perfect manual scrub) and resquashed the main SFS. I am an all intel shop at this point, four i5s, two or three core 2 duos, and two Bay Trail desktops. Stopped using samba partly because of throughput and reliability issues with large files and partly just because it made me nervous. I just keep a USB3 HDD or two by my main computer and back up and transfer using them. It's fast and bulletproof and the extra walking doesn't hurt me. The space saved on the install doesn't matter to me at this time since my current hardware is all capable enough but I was just curious.
Things that I've tried and work here on this stripped version of upupbb:
My integrated pcmanfm and trashcan, glxgears, pmusic, gnome-mplayer, Slimjet 18.0.5.0 run-as-spot from SFS, Sylpheed, QtWebBrowser 3.8.5 portable install, gnumeric (simple financial spreadsheet), abiword (create, format, and print a testpage), networked printers (one HP4500 all-in-one and a Brother 2170 laserprinter) The Brother was already installed. I turned the firewall off and installed the usual HPlite. Both printers were autodetected by CUPS and the HP installed and printed a test page perfectly.
Things that fail: Haven't run into one yet. Certainly video driver dependent so I'm probably an outlier here with the all intel and pretty simple use but... I'll use this pup for a while and see what does break. I like it for it's non-gvfs nature.
Just fooling around![Very Happy :D](./images/smilies/icon_biggrin.gif)
Update: A few days of steady use, including a kernel swap and the usual system tests of that, and I haven't found anything that is broken on this platform and pup by this change. I found my stripper script so the samba removal is complete and checked per the .packages list.

Pups currently in kennel :D Older LxPupSc and X-slacko-4.4 for my users; LxPupSc, LxPupSc64 and upupEF for me. All good pups indeed, and all running savefiles for look'n'feel only. Browsers, etc. solely from SFS.
Xenial Pup 64 small
Hello! I am using Xenial Pup 7.5 with the following modifications:
Removed:
Palemoon;

swrast_dri.so,
virtio_gpu_dri.so,
vmwgfx_dri.so, all in usr / lib / dri.
puppy_xenialpup64_7.5.sfs got 187 Mb. The kernel is 4.14.63, extracted from q.sfs of the latest version of Barry Kauler's Quirky Xerus 64 8.6, which was very well done with the following patches:
CPU vulnerabilites: Mitigation:
l1tf PTE inversion mitigation
meltdown PTI mitigation
spec_store_bipass * vulnerable
specter_v1 _user pointer sanitization
spectre_v2 full generic retpoline
On my PC (Intel (R) Pentium (R) CPU G3260 @ 3.30GHz), it is working very well. On an Ultra PC Ultra Liva X2 (Celeron Dual Core N3060) very well.
I do not recommend this for users with little knowledge of their PC and each computer has its specific configuration.
