If your aim is generate per-function stack usage for all functions in the TF-A bootloader images then that should be sufficient, yes. To my knowledge, however, the `-fdump-ipa-cgraph` is a GCC-specific developer option, and is not supported by armclang.

Subject: [TF-A] Re: Stack usage

Hello Chris,
Good morning,

In our makefile we have added like this
TF_CFLAGS               +=      $(CPPFLAGS) $(TF_CFLAGS_$(ARCH))                \
                                -ffunction-sections -fdata-sections             \
                                -ffreestanding -fno-builtin -fno-common         \
                                -O0 -std=gnu99 -fstack-usage -fdump-ipa-cgraph
Here anything do I need to change?
