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.
Jeff
