#------------------------------------------------------------------------------
# SPEC CPU2017 config file for: gcc / g++ / gfortran on Linux ARM systems
#------------------------------------------------------------------------------
# 
# 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):    5.3, 6.2
#    Operating system(s):    Ubuntu 16.04
#    Hardware:               Cavium ThunderX, HPE Moonshot
#
# If your system differs, this config file might not work.
# You might find a better config file at http://www.spec.org/cpu2017/results
#
# Known Limitations 
#     It is possible that you might encounter compile time or run time errors 
#     with older versions of GCC (for example, 4.x)
#     Recommendation: Use a newer version of the compiler.
#                     If that is not possible, try reducing the optimization. 
#
#
# Compiler issues: Contact your compiler vendor, not SPEC.
# For SPEC help:   http://www.spec.org/cpu2017/Docs/techsupport.html

%define label riscv                # (2)      Use a label meaningful to *you*.

#--------- How Many CPUs? -----------------------------------------------------
# Both SPECrate and SPECspeed can test multiple chips / cores / hw threads
#    - For SPECrate,  you set the number of copies.
#    - For SPECspeed, you set the number of threads. 
# See: https://www.spec.org/cpu2017/Docs/system-requirements.html#MultipleCPUs
#
#    q. How many should I set?  
#    a. Unknown, you will have to try it and see!
#
# To get you started, some suggestions:
#
#     copies - This config file defaults to testing only 1 copy.   You might
#              try changing it to match the number of cores on your system, 
#              or perhaps the number of virtual CPUs as reported by:
#                     grep -c processor /proc/cpuinfo
#              Be sure you have enough memory.  See:
#              https://www.spec.org/cpu2017/Docs/system-requirements.html#memory
#
#     threads - This config file sets a starting point.  You could try raising 
#               it.  A higher thread count is much more likely to be useful for
#               fpspeed than for intspeed.
#

#  - 502.gcc_r/602.gcc_s             needs -fgnu89-inline or -z muldefs
#  - For 'base', all benchmarks in a set must use the same options.   
#  - Therefore, all base benchmarks get the above.  See:
#       www.spec.org/cpu2017/Docs/runrules.html#BaseFlags  
#       www.spec.org/cpu2017/Docs/benchmarks/500.perlbench_r.html

   # -----------------------
   # About the -fno switches
   # -----------------------
   #
   # For 'base', this config file (conservatively) disables some optimizations.
   # You might want to try turning some of them back on, by creating a 'peak' 
   # section here, with individualized benchmark options:
   #
   #        500.perlbench_r=peak:
   #           OPTIMIZE = this
   #        502.gcc_r=peak:
   #           OPTIMIZE = that 
   #        503.bwaves_r=peak:
   #           OPTIMIZE = other   .....(and so forth)
   #
   # If you try it:
   #   - You must remove the 'basepeak' option, above.
   #   - You will need time and patience, to diagnose and avoid any errors.
   #   - perlbench is unlikely to work with strict aliasing 
   #   - Some floating point benchmarks may get wrong answers, depending on:
   #         the particular chip 
   #         the version of GCC 
   #         other optimizations enabled
   #         -m32 vs. -m64
