# For each tag specified on the command line we add -D<tag> to the cflags to
# allow for #idefs in the code.
#
# We apply the following transformations (via the tr command):
# 1. Convert the tag name to uppercase (TAGS=xtensa_hifimini -> -DXTENSA_HIFIMINI)
# 2. (Temporarily) Replace dash with underscore (TAGS=cmsis-nn -> -DCMSIS_NN)
#
# Transformation 2 is needed because CMSIS-NN is not a valid macro name.
#
# TODO(b/168824958): remove dash->underscore transformation once the cmsis-nn
# and ethos-u directories have been renamed.
