--- Comment #2 from majun <majun4950646 at 163 dot com> --- (In reply to Richard Biener from comment #1) > Confirmed, mine. This happens because get_inner_reference converts nchar_14 > to sizetype and thus we analyze the evolution of (uint64_t) nchar_14 which > isn't affine unless we can prove nchar_14 will never wrap in its type > (unsigned int). how does scev handle type conversion now ? I see many type conversion in ev function,And I think this may casue vect/para failed for some loops. I hit a parallel problem caused by scev type conversion handle in spec2k6 410. for now I have no idea with this problem,I will open a new bug to report this. thanks! ---Jun
