Rafael Espindola	a6c0249619	Convert linkonce* to weak* instead of strong. Also refactor the logic into a helper function. This is an important improvement on mingw where the linker complains about mixed weak and strong symbols. Converting to weak ensures that the symbol is not dropped, but keeps in a comdat, making the linker happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195470 91177308-0d34-0410-b5e6-96231b3b80d8	2013-11-22 16:14:30 +00:00

Convert linkonce* to weak* instead of strong.

Also refactor the logic into a helper function. This is an important improvement
on mingw where the linker complains about mixed weak and strong symbols.
Converting to weak ensures that the symbol is not dropped, but keeps in a
comdat, making the linker happy.

Check isDiscardableIfUnused, rather than hasLocalLinkage, when bumping

GlobalValue linkage up to ExternalLinkage in the ExtractGV pass. This
prevents linkonce and linkonce_odr symbols from being DCE'd.
