Hi, Richard,
With resolution file generated by GOLD (or I am going to hack gnu LD), is
externally_visible attribute still needed to annotate those symbols accessed
from non-LTO objects when compiling with -fwhole-program.
In theory, it shouldn't be needed since LTO has all information. But what
about current implementation. I checked relevant source files and can't
get immediate clue.
Thanks,
Bingfeng
