It has to follow the ABI specification, so $fp is the only > possibly problematic one, and that's excluded by -fomit-frame-pointers. Daniel Jacobowitz reported the problem which indeed was about $30. Since the kernel uses -fomit-frame-pointer by default (and -O1 enables it by default on MIPS anyway) I would assume his kernel was built using that option. Maybe he can elaborate ... Anyway, gcc could load next weeks lucky lottery numbers into the s-registers after saving them. That'd break save_static but not the ABI which only promises to restore the old values in s-registers on return. Ralf
