Please don't do html mail... And please CC the linuxBIOS list. I admit it is not a real substitute for documentation but with these kinds of discussions happening in public the information is distributed more widely and more people can answer question or take action based on a conversation.

That sounds like a good idea. I will see about that.

It would also be helpful to have a short comment in the C code that depends on romcc to say so.  Otherwise, it's a real head-twister to see a C program setting up mtrr's!  ;^)<br>

Well changing mtrrs is not romcc specific. We do that even in the freebios1 tree. With romcc you can just run the C code earlier. The real difference is that with romcc rdmsr wrmsr are done with builtins whereas with gcc you need to do inline asm. I am in the processes of setting of the APIs in LinuxBIOS so that most code will work with or without romcc. You comment reminds me that I still have to sync of the rdmsr/wrmsr APIs...

<br> Nice piece of work, thanks in advance for the fun I'm going to have with it!<br>

Welcome. And BTW I have just committed a change that reduces the algorithmic complexity of parts of the register allocator. So the compiler now should have a much more reasonable runtime. Eric
