required C optimizations?

Hi all,

I'm trying to get an idea of the minimum compiler requirements necessary
to build a Linux kernel, excluding parsing requirements. For example,
IIRC, some portions of the code depend on 'static inline' working and
decent constant propagation/folding.

Are you guys aware of a list of such examples, either in your own head
or written down somewhere?

If you're wondering what this is about, I'm playing around with "tinycc"
(http://www.tinycc.org/) ... it's nowhere near building a kernel, being
basically a C parser that emits binary code, but I wanted to get an idea
of the obstacles.
