Subject: [llvm-objdump] Simplify PrintHelpMessage() logic
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1e6eb4cd5098297e4776605183e1147e9b3cfb7e;p=llvm

[llvm-objdump] Simplify PrintHelpMessage() logic

This relands rL358418. It missed one test that should also use -macho
Note, all the other -private-header -exports-trie tests are used
together with -macho.
