From 7e77d5eee711a5ef7d7f6676627e802f8a937bb6 Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Thu, 16 Nov 2017 15:56:44 -0800 Subject: [PATCH] arm64: pass code model to LLVMgold With LTO_CLANG, even if we pass -mcmodel to clang, the flag isn't stored in the generated LLVM IR, which means it won't be used for the actual compilation at link time. Therefore, the flag needs to be passed to LLVMgold to actually take effect.
