# This is a work around for a bug in CCACHE which interacts very badly with
# some features of RIOT and of murdock. The result is that ccache is
# ineffective (i.e. objects are never reused, resulting in extreme cache miss
# rate) and murdock becomes slow.
#
# - CCACHE thinks that -gz by itself enables debugging, which is not true.
#   see https://github.com/ccache/ccache/issues/464
#   - When debug info is included, CCACHE hashes the file paths, as these
#     influence the debug information (the name of compile units and/or their
#     "comp_dir" attribute)
# - Riot does not set -fdebug-prefix-map. This is not that easy as it may not
#   be supported in every toolchain (some are quite old).
# - Murdock builds PRs in different directories each time.
#
# It is only the combination of these three factors which causes this bug.
