[PATCH] D108881: [clang][driver] Honor the last -flto= flag even if an earlier -flto is present

[Usman Nadeem via Phabricator via cfe-commits]

mnadeem added inline comments.


================
Comment at: clang/lib/Driver/ToolChains/Clang.cpp:4495-4497
+        Arg *A = Args.getLastArg(options::OPT_flto, options::OPT_flto_EQ);
+        if (A && A->getOption().matches(options::OPT_flto))
           CmdArgs.push_back("-flto");
----------------
Another option would be to do the following, but i am not sure if there is any code that explicitly checks for/needs "=full":

```
if (D.getLTOMode() == LTOK_Thin)
    CmdArgs.push_back("-flto=thin");
else
    CmdArgs.push_back("-flto");
```
