Subject: [IAS] Teach -cc1as about the 'target-abi' option.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=71f5be1ed0f8a70827b27a867945a67dc7417666;p=platform%2Fupstream%2Fllvm.git

[IAS] Teach -cc1as about the 'target-abi' option.

Summary:
When using the IAS from clang, the 'target-abi' option gets passed to cc1as, but cc1as doesn't know about it and gives an "unknown argument" error.

This is fixed by adding the 'CC1AsOption' flag to the 'target-abi' option in CC1Options.td.
