[PATCH] Statepoint infrastructure for garbage collection

[Sanjoy Das]

Hi,

> Is there also an issue with your runtime restoring callee saves when unwinding? This is unfortunately a platform-specific issue that LLVM JITs currently face. You may have solved it given you're only targetting one platform. Please bring it up in the MCJIT BOF Tuesday if it's an issue for you.

As of now, we don't need this for GC, but we need this for
deoptimization support.  We parse the .eh_frame section for this
currently.

I'll let Philip answer the rest of your email. :)
