From 565cbdc2fec92ef2ae75995e06e69172ed2edecd Mon Sep 17 00:00:00 2001 From: Mark Charlebois Date: Tue, 20 Nov 2012 22:13:10 +0100 Subject: LLVMLinux: Add support for clang to compiler.h and new compiler-clang.h Add a compiler-clang.h file to add specific macros needed for compiling the kernel with clang. Initially the only override required is the macro for silencing the compiler for a purposefully uninintialized variable.
