config TOOLPREFIX
string "Compiler toolchain path/prefix"
default "xtensa-esp32-elf-"
help
The prefix/path that is used to call the toolchain. The default setting assumes
a crosstool-ng gcc setup that is in your PATH.
config PYTHON
string "Python 2 interpreter"
default "python"
help
The executable name/path that is used to run python. On some systems Python 2.x
may need to be invoked as python2.

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.

choice OPTIMIZATION_ASSERTION_LEVEL
prompt "Assertion level"
default OPTIMIZATION_ASSERTIONS_ENABLED
help
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.
config OPTIMIZATION_ASSERTIONS_ENABLED
prompt "Enabled"
bool
help
Enable assertions. Assertion content and line number will be printed on failure.
config OPTIMIZATION_ASSERTIONS_SILENT
prompt "Silent (saves code size)"
bool
help
Enable silent assertions. Failed assertions will abort(), user needs to
use the aborting address to find the line number with the failed assertion.
config OPTIMIZATION_ASSERTIONS_DISABLED
prompt "Disabled (sets -DNDEBUG)"
bool
help
If assertions are disabled, -DNDEBUG is added to CPPFLAGS.
