What is a “flags file”? What does the message Unknown Flags mean in a report?
a. SPEC CPU2006 provides benchmarks in source code form, which are compiled under control of SPEC’s toolset. Compilation flags (such as -O5 or -unroll) are detected and reported by the tools with the help of flag description files. Therefore, to do a complete run, you need to (1) point to an existing flags file (easy) or (2) modify an existing flags file (slightly harder) or (3) write one from scratch (definitely harder). Find an existing flags file by noticing the address of the .xml file at the bottom of any result published at www.spec.org/cpu2006. You can use the –flagsurl switch to point your own runspec command at that file, or you can reference it from your config file with the flagsurl option. For example: runspec –config=myconfig –flagsurl=http://www.spec.org/cpu2006/flags/sun-studio.xml int You can download the .xml flags file referenced at the bottom of any published result at www.spec.org/cpu2006.
