Ok.

Well I thought of this already and tried my test case without any flags but -Wall, with -O2 and -Os. Same result. I also compiled my test case with the options used by the kernel (which ATM isn't compiled with -Os), same thing.
I've attached to this email a tarball of what I use to test the compiler/binutils. It's faster than recompiling the whole kernel on these slow machines! -- Mathieu Chouquet-Stringer mchouque@free.fr [unhandled content-type:application/x-gzip] | |
