Re: How to understand gcc source code?

* what is the proportion of cross-compilation? I have no real clue. I would suppose that during all the GCC runs in the last month, only a minority was cross-compilation (for some embedded systems). Of these, what are the favorite target machines & systems. I really don't know this one (maybe ARM or PowerPC32?).

Don't forget all the Linux based routers like OpenWRT and Netgear devices that are cross compiled using GCC. GCC+Linux is very scalable !

Aren't they often ARM boards running Linux? But usually, you cross compile (on Linux/x86 or AMD64, towards target Linux/ARM or whatever)...

AFAIK Mainly MIP's based CPU's.

I'm more interested in figures from the GCC user perspective. A device with some embedded Linux, even if sold in the millions, has its software probably compiled only a few times for the last release (and perhaps a thousand times for its entire development). Linux based routers could not run the GCC compiler (inside the router)!

Yes, I was not totally clear in my "GCC+Linux" comment :)
