README.md

• Here, we describe the process to follow to generate ll files from the cpu-spec-2006 and the cpu-spec-2017 folders.

CPU 2006

• Run installation using the command bash install.sh.
• Create config file, using config_clang14_cpu2006.cfg.
• Change the following compilation parameters to reflect the appropriate llvm version.
  • CC, CXX
• To COPTIMIZE, and CXXOPTIMIZE, also add -S -emit-llvm -Xclang to ensure that compilation stops appropriately without errors.
• Copy the config file to the config folder in the cpu2006install folder.
• Source the install. source shrc
• Run the command
  • runspec --config config_clang16_cpu2006.cfg --tune=base --action=build --rebuild --define build_ncpus=1 int fp
• Once the .o files are generated, run the script (collect_ir/spec/get_ll_spec.sh) with appropriate changes to get these files together in the repo.

CPU 2017

• Run installation.

• Create config file, using config_clang14_cpu2017.cfg.

• Change the following compilation parameters to reflect the appropriate llvm version.

  • CC, CXX, CLD, FLD

• To COPTIMIZE, and CXXOPTIMIZE, also add -S -emit-llvm -Xclang to ensure that compilation stops appropriately without errors.

• Copy the config file to the config folder in the cpu2017install folder.

• Source the install. source shrc

• Run the command

  • runcpu --config config_clang16_cpu2017.cfg --tune=base --action=build --rebuild --define build_ncpus=1 intrate fprate intspeed fpspeed

• Once the .o files are generated, run the script (collect_ir/spec/get_ll_spec.sh) with appropriate changes to get these files together in the repo.

• Once the ll, .o files are generated, collect them in an ll_files.txt file and proceed with generating the triplets.
