Bug ID: 105613
Summary: Compute shader locks up within nested "for" loop
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Vulkan/radeon
Assignee: mesa-dev@lists.freedesktop.org

Compute shader (SPIR-V version)
Hellblade: Senua's Sacrifice (via wine+dxvk) locks up shortly after the intro
videos before reaching the main menu because of an issue with the attached
compute shader.
Tested on an RX 480 with mesa-git (e8d9b7ab0) and LLVM 6.0.0, as well as LLVM
7.0.0-svn.
The attached GLSL version of the shader can also be used to reproduce the hang
when compiling it back to SPIR-V, and it contains a modified but functionally
equivalent code path which works as expected.
