2006-05-11 Richard Guenther <rguenther@suse.de> PR middle-end/27529 * fold-const.c (fold_unary): Handle intermediate conversion to a pointer type like intermediate conversion to an integer type in folding of (T1)(T2)var to var. Match the code to the comment in the final conversion for (T1)(T2)var to (T1)var regarding to type precision. Rather than disallow T1 being of pointer type, assert that both T1 and var are of pointer type or not. Make sure not to fall over the frontends lazyness wrt array to pointer decay though. * gcc.dg/tree-ssa/foldcast-1.c: New testcase. From-SVN: r113692
