Converting ISPC compilation to clang format.

[mike lojkovic]

I have some code I'm trying to translate the compiler arguments to something compatible with clang. I'm trying to use ccache, and the ispc compiler options are not recognized by it.

ISPC switches are definitely not compatible with clang switches. Could you point me to the ccache documentation stating the requirements to compiler switches format?

I think it would be easier to add ISPC support to ccache directly, but not hacking the issue around making switches look like clang switches.

PS it's better to have questions posted to github discussions at https://github.com/ispc/ispc/discussions so more people can see it and participate.

ccache can compile ISPC. It just doesn't cache it very well. I misread the ISPC documentation, as clang supporting ISPC too. How ccache seems to work now is it just passes the ispc calls directly to the compiler. I don't think they cache it very well, if at all, considering it has B level support. If they had it I think it would greatly benefit Unreal on Linux.
