So far: LLVM Master & Mesa Master fail LLVM Master & Mesa 17.1.5 (won't compile) LLVM 4.0.1 & Mesa Master works (gallium hud renders strangely - no plot) LLVM 4.0.1 & Mesa 17.1.5 works This is a Tonga M395X, nothing shows up in dmesg or the logs
I tried adding a borderlands 2 core dump but it was too big popped it on Google Drive: https://drive.google.com/a/fireburn.co.uk/file/d/0BySKFkadlRnpTEhWbVp2SV9jNHc/view?usp=sharing Games I've seen issues with Borderlands 2, BioShock Infinite, Civilization 6, Tomb Raider I can try bisecting LLVM, but it takes forever to compile, is there anything else I can do in the mean time? I don't think this is related to Bug 101876, reverting 5124bf982393114862f44ee62fa361027faa7c29 makes no difference
Sorry Civ 6 works fine Interestingly the Talos Principle works fine in 64bit for OpenGL and Vulkan but fails to start in 32bit for either of them Under Vulkan: WARNING: radv is not a conformant vulkan implementation, testing use only. mesa: for the -simplifycfg-sink-common option: may only occur zero or one times!

I've switched on debugging and the issue has gone away, will check to see if this is been fixed upstream, or if having debugging sidesteps the issue
So this only seems to happen if I compile LLVM with GCC 7.1, I don't see the issue if it's compiled with Clang. The problem also goes away when I compile with debugging on
I can confirm a very similar issue on my SI Cape Verde (HD8850M GCN1.0) using the amdgpu driver with mesa. It happens even if I compile mesa's `xdemos` with -m32 in which case most of the binaries produce a segfault pointing to drmGetVersion(). Can you confirm the same thing on your end? Steps to reproduce: 1) Compile xdemos with -m32 2) Load `glthreads` in gdb 3) Switch DRI on inside gdb via 'set environment DRI_prime=1' 4) After you run the program ('r'), and it segfaults, try and see what 'bt' produces. For me its the following: #0 0xf7a9c001 in ?? () from /lib32/libc.so.6 #1 0xf7a9bceb in strdup () from /lib32/libc.so.6 #2 0xf7735c55 in drmGetVersion () from /usr/lib32/libdrm.so.2 #3 0xf71a1acc in amdgpu_winsys_create () from /usr/lib32/dri/radeonsi_dri.so #4 0xf69152d8 in ??

() from /usr/lib32/libGL.so.1 #8 0xf7de040c in ?? () from /usr/lib32/libGL.so.1 #9 0xf7dde789 in glXChooseVisual () from /usr/lib32/libGL.so.1 #10 0x0804a483 in create_window () #11 0x0804abe9 in main () Note 64bit binaries work flawlessly. Using gcc 8 alpha here.
Also, the llvm issue indeed goes away when adding debug support. I think this might be related to a race condition caused by recent versions of gcc.
(In reply to Rafael Ristovski from comment #5) > #0 0xf7a9c001 in ?? () from /lib32/libc.so.6 > #1 0xf7a9bceb in strdup () from /lib32/libc.so.6 > #2 0xf7735c55 in drmGetVersion () from /usr/lib32/libdrm.so.2 This looks like a known regression in the kernel's core DRM code, fixed in newer kernels.
I'm running the latest agd5f's 4.14-wip branch, is that not new enough?
(In reply to Mike Lothian from comment #8) > I'm running the latest agd5f's 4.14-wip branch, is that not new enough? That branch might not have the fix for the 32-bit drmGetVersion regression yet, and I don't think that alone explains your issues anyway.
Which branch would you recommend?
So I think I've tracked this down LLVM GCC 6.3.0 & Mesa GCC 6.3.0 Works LLVM GCC 6.3.0 & Mesa GCC 7.1.0 Broken LLVM GCC 7.1.0 & Mesa GCC 6.3.0 Works LLVM GCC 7.1.0 & Mesa GCC 7.1.0 Broken I'm not sure why compiling Mesa with GCC 7.1.0 breaks 32bit rendering on just radeonsi GCC 7.2.0 is released in a week or so, I'll retest then

Since you compile with -march=native and using Skylake, you might also hit: https://bugs.freedesktop.org/show_bug.cgi?id=101484 Just a guess though.
What arch would you recommend testing with?

Memory map: ======== +0x66Aborted (core dumped) Once I compiled Mesa with debugging too everything goes back to working CFLAGS="-O2 -march=native -ggdb" CXXFLAGS="${CFLAGS}" LDFLAGS="-Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -fuse-ld=bfd" FEATURES="${FEATURES} nostrip" USE="debug valgrind"
So I tried dropping the -march=native and now it all works no matter what version of GCC I use. So it looks like GCC 7+ is miscompiling 32bit apps with -march=native I then added in -mbmi which broke things again and I finally tested with -march=native -mno-bmi which worked
So you agree that this is the same issue like: https://bugs.freedesktop.org/show_bug.cgi?id=101484 Marking duplicate?
Yes I believe this is a duplicate, I was only seeing issues with 32bit apps however I opened https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81763 with the GCC folk and they're asking for a reduced test case - I've no idea how to do that
I'm not totally sure this is the same bug, #101484 seems to suggest that reverting 2b8b9a56efc24cc0f27469bf1532c288cdca2076 fixes the issue (it doesn't for me) and they don't get segfaults, I don't have issues with GCC 6.3 whereas they're seeing it on and older GCC 5 (I think)
This was GCC related I think
