ld-linux --verify exit codes

Question

Checking the source from /usr/bin/ldd, I see that it uses ld-linux to find the dependencies of an executable, although it first calls ld-linux with the --verify argument. Then the script acts differently according to the exit code of the ld-linux --verify call.

The man page for ld-linux does not provide any info on exit codes, and a Google search turns nothing of value. Is there some documentation anywhere (other than by looking at ld-linux's source code) that provides a list of exit codes for ld-linux --verfify and their respective meanings?

Answer 1

I did some experiments and exit status is zero on success and 1 on failure. This includes grotesque abuse such as asking it to verify a shell script.

You'd be safe assuming zero on success, nonzero on failure, and no other information.
