Makefile-Tasking-Tricore/custom_compiler_yaml_tasking.py

##
# This script runs one or more TASKING compilers and gathers information
#  for CLion's Custom Compiler definitions file, see
#  https://blog.jetbrains.com/clion/2021/10/clion-2021-3-eap-custom-compiler/
#  https://www.jetbrains.com/help/clion/custom-compilers.html
#
#  The script is tested against TASKING VX-toolset v6.3r1 for Infineon TriCore
#    `output_filename`, `tasking_install_folder`, `tasking_platform_suffix`, `c_additional_compile_switches`, and
#    `cpp_additional_compile_switches` variables can be adjusted to fit another toolset variant
