Subject: [Driver] Register effective triple before get arm float abi.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=14840f889232ae3a896505b734d409f6acfcd536;p=clang

[Driver] Register effective triple before get arm float abi.

Summary:
We need to register effective triple before calling `getARMFloatABI`.
Add missing code when `--print-libgcc-file-name` is passed.
