LLVM Clang 3.3/3.4 AMD FX-8150 Bulldozer Benchmark Compiler AMD FX-8150 Eight-Core testing of LLVM Clang compiler. LLVM Clang 3.1, LLVM Clang 3.3, and LLVM Clang 3.4 (from mid June) compiler benchmarks under Ubuntu Linux from AMD FX Bulldozer Eight-Core CPU. Benchmarks for a future article on Phoronix by Michael Larabel. The LLVM Clang 3.2 compiler testing had to be skipped due to instability problems on this particular system.
