+## In this test we check that short command line options can be merged.

 ## Check merged args produce identical output to when not merged.

+## Check that the output without -a (--all) option is the same. We do it
+## to verify that each of the options is handled, and not just the first
+## one nor just -a, which triggers all other options.

+## -e (--headers) is equivalent to setting --file-headers (-h),
+## --program-headers (-l) and --section-headers (-S).
+## Check that the output without -e is equal to the output with it.
+## We do not use -a in this test either.

 ## llvm-readobj does not support merged args, because it also supports some old
