* real.c (real_floor, real_ceil): Tweak to allow input and output
arguments to overlap. (real_round): New function to implement round(3m) semantics. * real.h (real_round): Prototype here. * builtins.c (fold_builtin_round): New function to constant fold round, roundf and roundl. (fold_builtin): Call fold_builtin_round for BUILT_IN_ROUND{,F,L}. * gcc.dg/builtins-29.c: New test case. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@76428 138bc75d-0d04-0410-961f-82ee72b054a4
