From 85fa2cc51104ee5b529ce85b12f4c8421888544f Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Tue, 31 Oct 2017 18:22:02 +0100 Subject: c6x: pass endianness info to sparse c6x depends on the macro '_BIG_ENDIAN' being defined or not to correctly select or define endian-specific macros, structures or pieces of code. This macro is predefined by the compiler but sparse knows nothing about it and thus may pre-process files differently from what gcc would. Fix this by passing '-D_BIG_ENDIAN' when compiling a big-endian kernel, like GCC would have done.
