Hi kbhuvanacbe,

armclang provides the `-fstack-usage` flag (e.g. `make CC=armclang CFLAGS=-fstack-usage`) which can report the stack usage for individual functions, but I’m afraid that call graph analysis is not currently possible as TF-A does not support linking with armlink outside of some specific niche situations.

Regards,

Chris

Subject: [TF-A] Stack usage

We have executed below command on terminal to get stack size using ARMCLANG compiler. but we are getting "undefined symbol".

armclang --target=arm-arm-none-eabi -march=armv8-a -c -g file.c -o file.o
armlink file.o --info=stack
armlink file.o --callgraph -o FileImage.axf

Could anyone answer me that how to get stack size using ARMCLANG compiler for TFA code.
