prompt "Optimization Level"
default OPTIMIZATION_LEVEL_DEBUG
help
This option sets compiler optimization level (gcc -O argument).
- for "Release" setting, -Os flag is added to CFLAGS.
- for "Debug" setting, -Og flag is added to CFLAGS.
"Release" with -Os produces smaller & faster compiled code but it
may be harder to correlated code addresses to source files when debugging.
To add custom optimization settings, set CFLAGS and/or CPPFLAGS
in project makefile, before including $(IDF_PATH)/make/project.mk. Note that
custom optimization levels may be unsupported.

bool "Debug (-Og)"

endchoice
config OPTIMIZATION_ASSERTIONS
prompt "Enable assertions"
bool
default y
help
Enable assertions.
If disabled, -DNDEBUG is added to CFLAGS.
