Handle ORDERED_EXPR, UNORDERED_EXPR. (op_symbol): Print unordered comparisons differently than ordered ones. * tree.def (LTGT_EXPR): New '<' tree code. * doc/c-tree.texi (Expressions): Document floating-point comparison nodes. Fold comparisons between floating point values. * fold-const.c (enum comparison_code): New, from #define'd constants. Define compcodes for unordered comparisons and for invalid transformations. (invert_tree_comparison): Add "honor_nans" parameter. (fold_truthop): Revamp to work on floating-point types too. (comparison_to_compcode): Support unordered comparisons. Use new enum comparison_code. (compcode_to_comparison): Likewise. (combine_compcodes): New function. (invert_truthvalue): Let invert_tree_comparison decide whether it is valid to fold the comparison. Fold ORDERED and UNORDERED even if flag_unsafe_math_optimizations is off, and the remaining even if flag_unsafe_math_optimizations is off but we are under -fno-trapping-math. (fold_relational_const): Integer modes do not honor NaNs. gcc/testsuite/ChangeLog: 2004-05-27 Paolo Bonzini * gcc.c-torture/compare-fp-1.c, gcc.c-torture/compare-fp-2.c, gcc.c-torture/compare-fp-3.c, gcc.c-torture/compare-fp-4.c, gcc.c-torture/compare-fp-3.x, gcc.c-torture/compare-fp-4.x, gcc.c-torture/pr15649-1.c: New.
