# 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# Recommendation: Use a newer version of the compiler.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
#------------------------------------------------------------------------------
#--------- Label --------------------------------------------------------------
# Arbitrary string to tag binaries
# Two Suggestions: # (1) EDIT this label as you try new ideas.
%define label riscv # (2) Use a label meaningful to *you*.
#--------- Preprocessor -------------------------------------------------------
%ifndef %{bits} # EDIT to control 32 or 64 bit compilation. Or,
% define bits 64 # you can set it on the command line using:
%endif # 'runcpu --define bits=nn'
%ifndef %{build_ncpus} # EDIT to adjust number of simultaneous compiles.
% define build_ncpus 16 # Or, you can set it on the command line:
%endif # 'runcpu --define build_ncpus=nn'
# Don't change this part.

#--------- How Many CPUs? -----------------------------------------------------

#
# 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.

# 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
