================
Comment at: clang/lib/Driver/ToolChains/Hexagon.cpp:212
   bool UseG0 = false;
+  bool UseLLD = Args.getLastArgValue(options::OPT_fuse_ld_EQ).startswith("lld");
   bool UseShared = IsShared && !IsStatic;

Fuchsia uses:

```
  const char *Exec = Args.MakeArgString(ToolChain.GetLinkerPath());
  if (llvm::sys::path::filename(Exec).equals_lower("ld.lld") ||
      llvm::sys::path::stem(Exec).equals_lower("ld.lld")) {
```
