However, actually cross compiling in +practice involves much more than just generating the right assembly code for a +target, it also requires having an appropriate tool chain (assemblers, linkers), +access to header files and libraries for the target, and many other details (for +example, the calling convention or whether software floating point is in +use). Traditionally, compilers and development environments provide little +assistance with this process, so users do not have easy access to the powerful +underlying cross-compilation abilities of clang.</p> + +<p>We would like to solve this problem by defining a new model for how cross +compilation is done, based on the idea of a <i>universal driver</i>. The key +point of this model is that the user would always access the compiler through a +single entry point (e.g., <tt>/usr/bin/cc</tt>) and provide an argument +specifying the <i>configuration</i> they would like to target.
