What is the current state of the JIT on Windows x64?
I have noticed intermittent conversation about past incompatibility
due to the calling convention idiosyncrasies, as well as some
suggestion from last fall that it was targeted for a fix in the 2.5
timeframe, but see no definitive conclusion. Is this working in 2.5,
in trunk, or likely to be in trunk soon?

Broken; at the very least, there's http://llvm.org/bugs/show_bug.cgi?id=3739 .
sad...
in my case, otherwise I would have asked if anyone had benchmarked the SysV/AMD64 calling convention vs the Win64 calling convention...
I personally want to know what is faster, but can't find any benchmarks, nor am that inclined in going through all the steps to get it working (installing a 64-bit windows, geting 64-bit compilation set up, and getting benchmarks to compare between Windows and Linux, ...).
but, alas, if anyone has tested this, I am hoping I can hear the results...
(sadly, I don't have anything available to accurately test Win64 on a Linux-based setup, but this could be technically more accurate than using Windows, since it would reduce the risk of OS-specific overhead differences...).
