Note that you can check the configuration sanitycheck used in the sanity-out folder, for example for hello_world with native_posix the folder is: sanity-out/native_posix/samples/hello_world/sample.helloworld/zephyr/.config
You can check there for CONFIG_NO_OPTIMIZATIONS=y
You also have the used make/ninja files there.

Dear All
Is there an option (or any instruction on how to modify the code) to disable all optimization in sanitycheck?
Purpose: When I was looking at the code coverage report generated by sanitycheck, there are signs that there may be optimization enabled, e.g., only the middle of three C statements was not covered and the program execution is linear. I was exploring command line option to disable optimization but cannot find any
Then I was not sure whether something was optimized away with "Z_SYSCALL_HANDLER(funcName);" statement, i.e. a syscall handler with empty body
Many thanks in advance Cinly
