Bob Wilson 313eeb0a47 Link with -rdynamic instead of -Wl,-export-dynamic. ... Recent versions of the OS X linker support this but follow the existing OS X linker convention of using an underscore in the option name, i.e., -export_dynamic. Rather than changing our configure scripts to check for that alternate spelling, it is simpler to just use the compiler's -rdynamic option and let it deal with translating that to the appropriate linker option. One potential disadvantage of this approach is that the compiler will typically ignore -rdynamic on platforms where it is not supported, so the HAVE_LINK_EXPORT_DYNAMIC in config.h will not necessarily show whether that option has any effect or not. I don't see any in-tree uses of that macro, so I'm assuming it is OK. llvm-svn: 187686		2013-08-02 22:51:06 +00:00
