# Clang tool executes cc1 commands in the same process after b4a99a0
# It causes increasing memory consumption for compilations where several
# source files are passed (for C++ application) or several build steps (e.g.
# for SYCL application we have host, device and integration header step
# per source file). Memory is not freed for all cc1 commands until end
# This change forces clang driver use old behavior untill memory issue
# is fixed.
