--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Wed Nov 22 12:35:26 2017 New Revision: 255054 URL: https://gcc.gnu.org/viewcvs?rev=255054&root=gcc&view=rev Log: PR tree-optimization/83044 * tree-vrp.c (vrp_prop::check_array_ref): If eltsize is not INTEGER_CST or is 0, clear up_bound{,_p1} and later ignore tests that need the upper bound. Subtract offset from get_addr_base_and_unit_offset only if positive and subtract it before division by eltsize rather than after it. * gcc.dg/pr83044.c: New test. * c-c++-common/Warray-bounds.c (fb): Fix up MAX value. Added: trunk/gcc/testsuite/gcc.dg/pr83044.c Modified: trunk/gcc/ChangeLog trunk/gcc/testsuite/ChangeLog trunk/gcc/testsuite/c-c++-common/Warray-bounds.c trunk/gcc/tree-vrp.c
