Subject: [llvm-nm] Add --portability as alias for --format=posix
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8a839cf959839b2ef6b8c8dc8d10fcc362ab14d3;p=llvm

[llvm-nm] Add --portability as alias for --format=posix

GNU nm supports this alias, so supporting it in llvm-nm makes it easier
to transition between the two.
