(indirect_refs_may_alias_p): Fix TARGET_MEM_REF without index tests. * gcc.dg/torture/pr48702.c: New testcase. Backport from mainline 2011-05-31 Jakub Jelinek <ja...@redhat.com> PR rtl-optimization/49235 * tree-ssa-address.c (gen_addr_rtx): Ignore base if it is const0_rtx. (create_mem_ref_raw): Create MEM_REF even if base is INTEGER_CST. * gcc.dg/pr49235.c: New test.
