Created attachment 143744 [details] Compute shader that triggers the crash Hello, trying to compile the attached compute shader (among others) causes the driver to segfault. The commit which introduced the issue is: commit 3235a942c16b61849bc16a710c53f0a7a5566f0d (HEAD, refs/bisect/bad) Author: Timothy Arceri <tarceri@itsqueeze.com> Date: Thu Dec 6 16:00:40 2018 +1100 nir: find induction/limit vars in iand instruction Please let me know if you need more info.
Sorry, it's been fixed I'm waiting on someone to review the patch. https://patchwork.freedesktop.org/patch/292850/
Fixed by: commit 427a6fee439b2df96edc813c56572169385772a6 Author: Timothy Arceri <tarceri@itsqueeze.com> Date: Tue Mar 19 12:09:36 2019 +1100 nir: only override previous alu during loop analysis if supported Users of this function expect alu to be a supported comparision if the induction variable is not NULL. Since we attempt to override the return values if the first limit is not a const, we must make sure we are dealing with a valid comparision before overriding the alu instruction. Fixes an unreachable in inverse_comparison() with the game Assasins Creed Odyssey.
