[Valgrind-developers] headaches abound.. platform support

[Greg C. <cha...@wi...>]

I'm trying to troubleshoot a very massive headache with the gcc driver 
on alpha, so I gave this a shot and found out the platform isn't 
supported.
I can find no listing of what is and isn't suported outside of the 
configure script itself. (Should maybe be in the FAQ?)

It looks like just about every platform except alpha is supported, so 
how much work is it to get a new platform supported (not sure how much 
needs to be added/modified)?
