[Jikesrvm-researchers] throwing exception from yield-points

[Adam W. <we...@cs...>]

Hello,
I need to throw a caught exception when executing yield operation. My 
problem is related to the optimizing compiler. Yield-points 
are not in the scope of the required exception handlers. I am assuming 
this happens because exception handlers are generated only for 
(potentially) exceptional instructions and yield-points are by 
default non-exceptional (at least the compiler does not know that they 
may throw my exception). 

I would like to ask if someone could help me to find out how and where to 
mark the yield-points as exceptional. The other instructions (or, more 
precisely, basic blocks containing those instructions) are marked as 
exceptional in OPT_BC2IR by calling rectifyStateWithExceptionHandlers() , 
but yield-points are inserted at a much later stage (in 
OPT_FinalMIRExpansion).

Thank you

Adam Welc
