additions... * fold-const.c (fold) <PLUS_EXPR>: Canonicalize X + -C as X - C for floating point additions, to keep real immediate constant positive. <MINUS_EXPR>: For floating point subtractions, only transform X - -C into X + C, and leave positive real constants as X - C. From-SVN: r84535

integer_type_node... * builtins.c (fold_builtin_fputs): Don't bother converting the return type to integer_type_node, as we've already checked that the result will be ignored. * tree-eh.c (tree_could_trap_p): Add support for -ftrapv such that signed addition, subtraction, multiplication, division, remainder, negation and absolute value may potentially trap. * fold-const.c (fold_ignored_result): New function to strip non-side-effecting tree nodes from an expression whose result is ignored. (fold_convert): Call fold_ignored_result when casting a value to VOID_TYPE. (omit_one_operand): Call fold_ignored_result on the "omitted" operand when building a COMPOUND_EXPR. (pedantic_omit_one_operand): Likewise. * tree.h (fold_ignored_result): Prototype here. * tree-ssa-ccp.c (ccp_fold_builtin): Call fold_ignored_result when we're going to ignore the result.
