[llvm-objdump] Move --start-address >= --stop-address check out of the -d code.

Authored by ychen on Jun 20 2019, 4:52 PM.



Move it into main function so the checking is effective for all actions user may do with llvm-objdump; notably, -r and -s in
addition to existing -d. Match GNU behavior.

prepare for patch on PR41911

I think the description should mention that the --start-address >= --stop-address check has been moved out of the -d code. This can be useful for -t -r

ychen retitled this revision from [llvm-objdump] Perform --start-address / --stop-address error checking to [llvm-objdump] Move --start-address >= --stop-address check out of the -d code..Jun 20 2019, 8:15 PM

Thank you @MaskRay. Description changed. I intentionally leave out -t since I suspect it is a bug. See my comment in

If this line (no command specified) gives diagnostics, the -d -r -s RUN lines may be unnecessary.

Does it make sence to include the address values here? And/or the option name?
It is not really clear from the error message text what is wrong it seems.

My comment is not directly related to change done in this patch though, so LGTM.

I think this change should only remove the -d part, not change the ordering of the --stop-address values.


I agree that it might be nice to improve the error message. I'm okay with that being a separate change though.
