Compiling LinuxCNC using a graphic card

Not that i compile a lot lately, but it just occured to me that i have not seen the above done, ever, for all software, not just LinuxCNC.
Given the huge amount of procesing power graphic cards have these days, is anyone aware of such a posibility?

Those GPU's have relative simple processors but a load of them in parallel. It will only be feasible if you have a compiler which uses the GPU (does not exist AFAIK) and a lot of classes which are very similar (so you can benefit from the parallelism).

Compiling is something you do once and use the result often. Therefore it is more beneficial to invest in algorithms which unleash the power of the GPU and not in the tooling to compile those algorithms.

I have several high end graphic cards collecting dust, so it was just an idea to do something with those.
Thank you.
