When I build my code with the following compiler option on STM32L4R9AI (Cortex M4) board with TizenRT (https://github.com/Samsung/TizenRT)
ARCHOPTIMIZATION += -fno-omit-frame-pointer -mapcs -mno-sched-prolog
I do not get a frame pointer (fp) for every call stack of the source code build.
When I take the object dump, I get following call stack >>
08000fb0 <stm32l4_dbgmonitor>: 8000fb0: b580 push {r7, lr}
Whereas, for cortex-R the object dump using the same compiler option (for artik053 board) looks as below >>
I am currently using using gcc version 6.3.0.
Any pointers on this issue would be helpful.
Thanks & Regards,
