bool "Undefined behaviour sanity checker"
help
This option enables undefined behaviour sanity checker
Compile-time instrumentation is used to detect various undefined
behaviours in runtime.

config UBSAN_SANITIZE_ALL
bool "Enable instrumentation for all of barebox"
depends on ARCH_HAS_UBSAN_SANITIZE_ALL
default y
help
This option activates instrumentation for all of barebox.
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 barebox image size increased
significantly.
config UBSAN_NO_ALIGNMENT
bool "Disable checking of pointers alignment"
default y if HAVE_EFFICIENT_UNALIGNED_ACCESS
help
This option disables the check of unaligned memory accesses.
This option should be used when building allmodconfig.
Disabling this option on architectures that support unaligned
accesses may produce a lot of false positives.
