The SPEC2006 runs I've done have all been within the framework of the llvm test suite, the LTO is run directly, rather than via an explicit -O4 option. The test-suite Makefiles themselves are probably the best place to look for the details of how that works if you're interested. SPEC2006 is hooked in via the Externals tests.

Hi Tobi,

Sorry, but no, I haven't run any of the fortran tests. Just the C/C++ ones.
