Question on tree-ssa-loop-im.c:for_each_index

[Richard Kenner]

    > 	x = <VIEW_CONVERT_EXPR some_type> 22;

     what is the semantics of this expression?  Should not this rather be

     x = <NOP_EXPR some_type> 22

     (or just INTEGER_CST:some_type 22)?

Depends what the type is.  If it's an array type, then there's no
simple equivalent expression.
