Compared to current head, I see consistent slightly over 5% slow-down with the patch in our memory profiler, using the same test I used previously. The 387M stack walks in ~960 secs become about ~1011 seconds with the patch. I don't think there are any ms_abi frames. Under what conditions would ms_abi support / preserving SSE register state be enabled? The matches I found in google codesearch were basically cygwin, wine and some EFI code.
