* Link with -rdynamic instead of -Wl,-export-dynamic.Bob Wilson2013-08-02
| | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187686 91177308-0d34-0410-b5e6-96231b3b80d8

This is silently hidden in GCC-hosted builds because the inner main looks like a nested function declaration, which GCC supports. In builds with compilers which do not support nested functions (by default), this was causing an error, which caused these autoconf checks to fail, leaving their options disabled. This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu llvm-gcc selfhost builds, among other things. This also includes a regenerated configure, as the diff is small and telling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102288 91177308-0d34-0410-b5e6-96231b3b80d8
