#------------------------------------------------------------------------------ # SPEC CPU(R) 2017 config for gcc/g++/gfortran on Linux x86 #------------------------------------------------------------------------------ # # Usage: (1) Copy this to a new name # cd $SPEC/config # cp Example-x.cfg myname.cfg # (2) Change items that are marked 'EDIT' (search for it) # # SPEC tested this config file with: # Compiler version(s): Various. See note "Older GCC" below. # Operating system(s): Oracle Linux Server 6, 7, 8 / # Red Hat Enterprise Linux Server 6, 7, 8 # SUSE Linux Enterprise Server 15 # Ubuntu 19.04 # Hardware: Xeon, EPYC # # If your system differs, this config file might not work. # You might find a better config file at https://www.spec.org/cpu2017/results # # Note: Older GCC # # Please use the newest GCC that you can. The default version packaged with # your operating system may be very old; look for alternate packages with a # newer version. # # If you have no choice and must use an old version, here is what to expect: # # - "peak" tuning: Several benchmarks will fail at peak tuning if you use # compilers older than GCC 7. # In that case, please use base only. # See: https://www.spec.org/cpu2017/Docs/overview.html#Q16 # https://www.spec.org/cpu2017/Docs/config.html#tune # Peak tuning is expected to work for all or nearly all # benchmarks as of GCC 7 or later. # Exception: # - See topic "628.pop2_s basepeak", below. # # - "base" tuning: This config file is expected to work for base tuning with # GCC 4.8.5 or later # Exception: # - Compilers vintage about 4.9 may need to turn off the # tree vectorizer, by adding to the base OPTIMIZE flags: # -fno-tree-loop-vectorize # # Unexpected errors? Try reducing the optimization level, or try removing: # -march=native # # Compiler issues: Contact your compiler vendor, not SPEC. # For SPEC help: https://www.spec.org/cpu2017/Docs/techsupport.html #------------------------------------------------------------------------------ #--------- Label -------------------------------------------------------------- # Arbitrary string to tag binaries (no spaces allowed) # Two Suggestions: # (1) EDIT this label as you try new ideas. %ifndef %{label} % define label "nix" # (2) Use a label meaningful to *you*. %endif #--------- Preprocessor ------------------------------------------------------- %ifndef %{bits} # EDIT to control 32 or 64 bit compilation.
