Subject: [Patch 1/7] BaseTools: Add ClangBase.lds for CLANG8 tool chain with max-page-size
Date: Fri, 26 Apr 2019 22:42:36 +0800 [thread overview]
Message-ID: <20190426144242.19024-2-liming.gao@intel.com> (raw)
In-Reply-To: <20190426144242.19024-1-liming.gao@intel.com>
LLVM LLD linker doesn't support common-page-size option. So, max-page-size
is used. To not impact GCC tool chain, new ClangBase.lds is added.
