 Well I'm horrified all right -- by the source.  For the record, I
 wouldn't count on this thing working indefinitely.
 
 I had to modify it a bit to get it to compile with mainline.  The
 use of asm register variables falls over the compiler's use of
 __builtin_memset, which requires edi.  I wish I could give a proper
 error message for this instead of ICE, but we don't save enough
 information long enough for me to remember that this is the user's
 fault.
 
 Anyway, I don't see anything that sticks out like a sore thumb wrt 
 either cross-jumping or gcse.  Can you be more specific?
