I did the below patch (changing all occurances of ashq) and it seems to
work well, my test program from yesterday now disassembles as:

00010630 <main>:
   10630:       40 00           .word 0x0040 # Entry mask: < r6 >
   10632:       c2 04 5e        subl2 $0x4,sp
   10635:       d4 56           clrf r6
   10637:       79 56 8f ff     ashq r6,$0xffffffffffffffff,r2
   1063b:       ff ff ff ff 
   1063f:       ff ff ff 52 


Would you like to send the patch upstream or do you want me to handle that?


Thanks,

Martin
