https://bugs.freedesktop.org/show_bug.cgi?id=66847 --- Comment #1 from Andreas Boll --- The llvm backends of r600g and the radeonsi on mesa 9.1 are only compatible with tstellar's llvm-3.2 branch. The llvm backends of r600g and the radeonsi on mesa 9.2 should be compatible with the official llvm-3.3 and llvm-3.4. It's not compatible with tstellar's llvm-3.2 branch. So I think we should abort in configure if someone wants to build mesa 9.1 with enabled llvm backend and llvm != 3.2. -- You are receiving this mail because: You are the assignee for the bug.
