--- Comment #8 from glisse at gcc dot gnu.org 2012-05-04 21:45:49 UTC --- Created attachment 27311 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27311 Wrap plus/minus This patch handles combinations of range/anti_range for PLUS_EXPR and MINUS_EXPR. I'll try to do MULT_EXPR later so that for -10<i<10 and -10<j<10 we get the same range for (unsigned)(i*j) and (unsigned)i*(unsigned)j.
