Carl-Daniel Hailfinger 9342d1be4e The ABI wrapper from r775 made the SHARED definitions obsolete. They're ... not that readable anyway, so kill them and use standard definitions instead. Introduce EXPORT_SYMBOL for shared symbols. EXPORT_SYMBOL tells the compiler to use the standard calling conventions for a given symbol and not to optimize it away. Benefits: - We can later use gcc -combine -fwhole-program without problems. - It's a correctness fix for some optimizations. - We could check for duplicated exported functions at link time. - We could check whether exported functions are linked into initram or stage2 by accident. - We could generate usage statistics and possibly optimize away unused shared functions. - Through the above points, significant side reductions of 10-40% Build and boot tested on qemu. Build tested on all targets. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Ronald G.
