[LLVMdev] getting gold plugin to work?

[Sandeep Patel]

Attached is the start of a patch to make the gold plugin work on
Darwin for use as a cross-compiler. There needs to be a build step
somewhere in llvm-gcc that copies it into libexec/<gcc
poop>/libLLVMgold.so, but I've been doing that manually for now.

It doesn't seem that simple use of -O4 results in the plugin learning
what subtarget is desired. I presume that the llvm-gcc driver needs to
pass -mcpu down through collect2 into ld somehow. Has anybody solved
this already? Perhaps we should finally just put the feature string
into the bitcode?
