If you (temporarily) put "volatile" on the variable, the compiler should not optimize it out. Obviously, this is a limited solution, but may get your past your problem.

Theoretically, you could compile individual files w/o optimization (e.g. if you compile it by hand, make shouldn't re-compile it). I doubt that you want to go there, though... > Fahd Abidi Good luck, gvb _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
