+Summary: ssapre creates invalid IL on amd64
+Some tests like mono/tests/appdomain1.exe fail on amd64 when run with
+-O=all, but they work when run with -O=all,-ssapre. 
+The error is the following:
+** (appdomain1.exe:24383): WARNING **: unable to label tree 0xafbef0
+ (stind.r8 regoffset[-0x58(%rbp)] (amd64_outarg_xmmreg_r8 r8const[2.000000]))
+** ERROR **: file mini.c: line 7477 (mini_select_instructions): should not
+be reached
+The problem here is that amd64_outarg_xmmreg_r8 is a 'stmt', it does not
+have a result, so it should not be stored in a variable. The invalid tree 
+above is created by the SSEPRE pass. I attached the output of -v -v -v -v,
+hope it helps.
