You can read out the stack pointer, and compare it against the symbol
_end which is provided by the linker and marks the last allocated SRAM
address.

While developing, you might monitor the stack usage by initially
filling up all SRAM with a known pattern, and then observe the amount
of stack that overwrites this pattern, e.g. using JTAG debugging.
