This option enables undefined behaviour sanity checker
|
|
Compile-time instrumentation is used to detect various undefined
|
|
behaviours in runtime. Various types of checks may be enabled
|
|
via boot parameter ubsan_handle (see: Documentation/ubsan.txt).

This option activates instrumentation for the entire kernel.
|
|
If you don't enable this option, you have to explicitly specify
|
|
UBSAN_SANITIZE := y for the files/directories you want to check for UB.
|
|
Enabling this option will get kernel image size increased
|
|
significantly.

help
|
|
This option enables detection of unaligned memory accesses.
|
|
Enabling this option on architectures that support unaligned
|
|
accesses may produce a lot of false positives.
