vector functions

Are there any functions for vector math which take advantage of the psp hardware? i.e, add two vectors, scale a vector, etc. I want c/c++, not assember too.

I looked in pspvfpu, but it doesn't seem to have any.

Thanks,

Thanks.

Can someone comment on how the community was able to reverse engineer libgu/gum, and not libvfpu?

It's probably not a question of "able to" as much as "wanted to". There was a lot of interest in libgu/gum (which we knew existed because Sony mentioned them on some public slides about the PSP). I don't know if we even knew anything about this "libvfpu", and either way we already have enough tools to use the VFPU if desired. Anyway, it sounds like you're making comparisions to the official SDK, which is certainly against whatever license terms came with your access to that information, and is also certainly not wanted here.
