I disagree, an implementation should be allowed to use the most efficient implementation possible for both interfaces. I would be using traps for both on sparc64 if that were really feasible on sparc64 (and actually with gcc-4.5's "asm goto" it might actually be now) The WARN and BUG macros, when implemented without traps, have serious implications for overall code size and register pressure. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
