Adds linker flag to display memory size information after building to STM32 platform libopencm3.cmake configuration file. Signed-off-by: Winford <winford@object.stream>
Make the local_heap_setup conditional unlikely to improve performance of memory allocation since this only is true only at the first memory allocation. Signed-off-by: Winford <winford@object.stream>
…latform Adds support for getting the current free heap size on STM32 platform using `erlang:system_info(atomvm_free_heap_size)`. Signed-off-by: Winford <winford@object.stream>
…2 platform Adds support for getting the current free heap size on STM32 platform using `erlang:system_info(atomvm_minimum_free_size)`. Signed-off-by: Winford <winford@object.stream>
…th atomvm_ prefix Adds new ESP32 erlang:system_info/1 heap memory keys `atomvm_free_heap_size` and `atomvm_minimum_free_size` to align with newly added STM32 memory keys. When the old keys are used a deprecation warning will be printed to the console to alert users to update to the new key names before the old keys are removed in the 0.8.x release cycle. Signed-off-by: Winford <winford@object.stream>
Adds documentation to the `erlang` module and "Programmer's Guide" for newly added STM32 system_info/1 keys. Signed-off-by: Winford <winford@object.stream>

Improves heap memory allocation performance by making the execution of the conditional
local_heap_setupfunctionUNLIKELYsince this is only matches on the the first heap allocation.Improves application memory debugging on STM32 by adding
system_info/1keysavm_free_heap_sizeandavm_minimum_free_sizewith functionality matching the esp32 keys for these statistics.Adds memory-size output report after compiling.
