Summary: [radeonsi LLVM] Segfault during OpenCL kernel
compilation
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: NEW
Version: git
Component: Drivers/Gallium/radeonsi
Product: Mesa
Created attachment 79901
--> https://bugs.freedesktop.org/attachment.cgi?id=79901&action=edit
Kernel that causes the segfault
I get a segmentation fault in LLVM with Tom Stellard's recent radeonsi compute
patches
(http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130520/175743.html)
with the attached kernel.
I can work around the issue when executing the if-block in the kernel
unconditionally or with the attached patch to LLVM.
Desc.OpInfo[0].RegClass equals -1 when the segmentation fault occurs.
