[PATCH] D142660: [AIX] supporting -X options for llvm-ranlib in AIX OS

[Digger Lin via Phabricator via cfe-commits]

DiggerLin updated this revision to Diff 542660.
DiggerLin added a comment.

1. rebase the code
2. for the `env OBJECT_MODE=` or is `env OBJECT_MODE=""` , the `ranlib` and `ar` in AIX OS , have different behaviors(ranlib looks as -X32 , but `ar` and `nm` output error ),

I change `llvm-ranlib` as the same behavior as `ar` and `llvm-ar`, output an error(I think output error is more reasonable).  and look env OBJECT_MODE unset as default 32-BIT for `llvm-ranlib`  as AIX OS command `ranlib` , `nm` ,`ar`.

bash-5.0$ env OBJECT_MODE= ar  -q tmp.a bug.patch
ar: 0707-133 The OBJECT_MODE environment variable has an invalid setting.

  OBJECT_MODE must be 32, 64, 32_64, d64, or any.

bash-5.0$ env OBJECT_MODE="" ar  -q tmp.a bug.patch
ar: 0707-133 The OBJECT_MODE environment variable has an invalid setting.

  OBJECT_MODE must be 32, 64, 32_64, d64, or any.

bash-5.0$ env OBJECT_MODE="" ranlib  tmpk.a
bash-5.0$ env OBJECT_MODE= ranlib  tmpk.a
