[PATCH] D118193: [llvm-nm] add a new option --bit-mode to specify the type of object file llvm-nm should examine

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

So I just found https://www.ibm.com/docs/en/aix/7.1?topic=n-nm-command

If the intention is to support AIX nm -X, I think it is fine because GNU nm's manpage says `-X  This option is ignored for compatibility with the AIX version of nm.  It takes one parameter which must be the string 32_64.  The default mode of AIX nm corresponds to -X 32, which is not supported by GNU nm.`
For other short options I would be concerned if there could be a potential conflict with GNU nm.

For the long option `--bit-mode`, I don't know whether it is necessary.
