+Subject: [PATCH] Use generic cpu when LLVM can't detect the host processor
+
+LLVM's CPU detection is very basic, it parses /proc/cpuinfo and uses
+information from their to look up CPUs in its own internal tables.
+These tables are incomplete, so it's not uncommon for LLVM to not
+be able to detect the CPU.
+
+Ideally pocl would use something better than llc --version for CPU
+detection, but for now we can at least fallback to the generic
+cpu when LLVM can't detect the host.
