llvm dev - Jul 2014 - [LLVMdev] LLVMgold.so in windows LLVM builds

I tried building it on windows with some CMake changes.
But unfortunatelym my clang crashes when it tries to access the LLVMgold
(not able to open it).

I have CCed Rafeal and Nakamura who might know why gold plugin in not
supported on Windows platforms.

Why is clang loading LLVMgold.dll?  I thought it's supposed to be loaded by
gold.

I don't think gold even produces COFF.  Are you trying to produce ELF on
Windows?

Gold is elf only but BFD ld supports the same plugins these days.

I have no idea if the plugin infrastructure works on windows or not, but it
could be made to work since all it needs is to find a single symbol in the
plugin.
