[PATCH 4.9 45/50] ARM: 8767/1: add support for building ARM kernel with clang

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stefan Agner <stefan@xxxxxxxx>

(commit c1c386681bd73c4fc28eb5cc91cf8b7be9b409ba upstream)

Use cc-options call for compiler options which are not available
in clang. With this patch an ARMv7 multi platform kernel can be
successfully build using clang (tested with version 5.0.1).
