[Barrelfish-users] CC variable

[Georgios Varisteas]

Hi Mothy,

My usage for this feature is twofold. First, I require to have custom source-to-source compilers (as front-ends) for the various task-based programming models I'm working with (i.e. Cilk, Wool). Moreover, I plan to try out Continuation-passing-style (like Cilk does) for my own runtime, which requires a custom code-generator to not use the stack. The purpose for CPS is to allow task-migration between threads of different cores.

This feature is not urgent since I'm only now starting the implementation, but it's good to know that it's doable. Since almost all of my research requires it though, I think I'll select the first and proper solution.

Hi Georgios,

We made an early decision to bury the binding of the C compiler fairly
deep down in Hake's architecture abstractions.  If there really is a
pressing need to specify the C compiler differently for different
modules in the same build architecture, we would need to add the
compiler name to the (ever-expanding) Opts record.  This is doable, but
it's a bit of work.

One alternative is to explicitly compile the C files by writing
low-level Hake combinators in your Hakefile.  Hake won't compile (or
calculate dependencies for) any C files which you don't explicitly hand
it, so you can treat any C file specially if you're prepared to forego
the convenience of the "build library" or "build application" functions.
  This might be the easiest way forward for a small module (how big is
it?).

This does require a bit more understanding of how Hake works, but most
of what you need should be in the Technical Note.

Hope this helps a bit...
