SPECint build times (secs) -O2 -O3 GCC 4.1.0 (20051117) 354 398 LLVM 1.6 (-Wl,-native-cbe) 802 805 So there appears to be a factor of 2 slowdown in LLVM. However, I know LLVM has a separate GCC invokation. It seems as if it emitted C code that is then compiled with GCC (I'm using -Wl,-native-cbe). I don't think this would be standard procedure in an integrated LLVM. Chris, how would one compare compile times? Not using -Wl,-native-cbe implies emitting bytecode, right?
