- 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.

- help
- Enabling this option compiles all IDF C++ files with exception support enabled.
-
- Disabling this option disables C++ exception support in all compiled files, and any libstdc++ code which throws
- an exception will abort instead.

- Enabling this option currently adds an additional ~500 bytes of heap overhead
- when an exception is thrown in user code for the first time.

-choice STACK_CHECK_MODE
- prompt "Stack smashing protection mode"
- default STACK_CHECK_NONE
- help
- Stack smashing protection mode. Emit extra code to check for buffer overflows, such as stack
- smashing attacks. This is done by adding a guard variable to functions with vulnerable objects.
- The guards are initialized when a function is entered and then checked when the function exits.
- If a guard check fails, program is halted. Protection has the following modes:
- - In NORMAL mode (GCC flag: -fstack-protector) only functions that call alloca, and functions with buffers larger than
- 8 bytes are protected.
- - STRONG mode (GCC flag: -fstack-protector-strong) is like NORMAL, but includes additional functions to be protected -- those that
- have local array definitions, or have references to local frame addresses.
- - In OVERALL mode (GCC flag: -fstack-protector-all) all functions are protected.
-
- Modes have the following impact on code performance and coverage:
- - performance: NORMAL > STRONG > OVERALL
- - coverage: NORMAL < STRONG < OVERALL

-config WARN_WRITE_STRINGS
- bool "Enable -Wwrite-strings warning flag"
- default "n"
- help
- Adds -Wwrite-strings flag for the C/C++ compilers.
-
- For C, this gives string constants the type "const char[]" so that
- copying the address of one into a non-"const" "char *" pointer
- produces a warning. This warning helps to find at compile time code
- that tries to write into a string constant.
-
- For C++, this warns about the deprecated conversion from string
- literals to "char *".
