Can someone from POWERPC comment on it? Hmm OK. I'm not really a toolchain person. The comment on DISCARDS says: * Some archs want to discard exit text/data at runtime rather than * link time due to cross-section references such as alt instructions, * bug table, eh_frame, etc. DISCARDS must be the last of output * section definitions so that such archs put those in earlier section * definitions. */ But I guess you're changing those semantics in your series.
