[Bug 1023614] New: [LLVM] [AMDGPU] libllvm shader compiler creates invalid code
http://bugzilla.opensuse.org/show_bug.cgi?id=1023614 Bug ID: 1023614 Summary: [LLVM] [AMDGPU] libllvm shader compiler creates invalid code Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: f.thiessen@gmx.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- (Not sure if component Kernel is ok, but as it affects the userspace gpu compiler i thought it might fit). I dicovered some crashes of applications since the upgrade to 42.2 (from 42.1). E.g. the steam game "Airscape" crashes with this error:
Steam_SetMinidumpSteamID: Caching Steam ID: 76561198142264195 [API loaded no] ATTENTION: default value of option force_s3tc_enable overridden by environment. [17690:0204/180824:ERROR:sandbox_linux.cc(297)] InitializeSandbox() called with multiple threads in process gpu-process LLVM triggered Diagnostic Handler: unsupported call to function exp10f in main [17656:0204/180825:ERROR:breakpad_linux.cc(1226)] crash dump file written to /tmp/chromium-gpu-process-minidump-237b21943f4e8916.dmp

The interessting part and the part it has in common with the other crashes is:
LLVM triggered Diagnostic Handler: unsupported call to function exp10f in main
I found out (thanks to the developer http://steamcommunity.com/app/317250/discussions/0/154644598513096190/ ) that this is caused by: https://bugs.freedesktop.org/show_bug.cgi?id=96495 https://reviews.llvm.org/D21282 So this is a bug in llvm < 3.9 and as Leap is using llvm 3.8 this affects Leap. -- You are receiving this mail because: You are on the CC list for the bug.
