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.

Assertions can be:

- Enabled. Failure will print verbose assertion details. This is the default.
|

- Set to "silent" to save code size (failed assertions will abort() but user
|
|
needs to use the aborting address to find the line number with the failed assertion.)
|
|
|
|
- Disabled entirely (not recommended for most configurations.) -DNDEBUG is added
|

to CPPFLAGS in this case.
