Subject: [PATCH] fold-const.c (fold_checksum_tree <case 't'>): Only look at
TREE_VALUES if the EXPR is an ENUMERAL_TYPE.
2004-06-13 Andrew Pinski <pinskia@physics.uc.edu>
* fold-const.c (fold_checksum_tree <case 't'>): Only
look at TREE_VALUES if the EXPR is an ENUMERAL_TYPE.
Only look at TYPE_MIN_VALUE and TYPE_MAX_VALUE if
EXPR is an INTEGERAL_TYPE or a scalar float type.
