<p style="margin-top:0;margin-bottom:0">I am trying to compile clang/llvm to target a specific CPU architecture (Intel Broadwell for instance). The intention here is that every time this specific compiler is run it will only ever generate code for that specific
CPU.<br>
<br>
To achieve this I would like to "bake-in" some command line arguments into the built compiler (things like -march), but still allow the user to provide extra command line arguments that may override the "baked-in" defaults.<br>
<br>
GCC provides a spec file to achieve this, but I can't find something equivalent for clang/llvm. Does such a thing exist for clang/llvm?</p>
