Hi,

.inst oxdeff is a udf (undefined) instruction. It is probably output in this way for historical reasons because GAS did not support that mnemonic yet. GCC outputs this because dereferencing a NULL pointing in undefined behavior. You will have expected code if compiling with -fno-delete-null-pointer-checks.

Best regards.
