The problem is that: name = MEM[(struct exp_ch3__make_predefined_primitive_specs__B_99__stream_op_tss_names___PAD *)D.14526_1156 + 4294967296B]; is expanded into sethi %hi(stream_op_tss_names.6060+4294967296), %l2 or %l2, %lo(stream_op_tss_names.6060+4294967296), %l2 which overflows since sethi is a 32-bit operator. Going through POINTER_PLUS_EXPR to expand a const addresss apparently bypasses checks for valid addresses in the back-end. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44993 ^ permalink raw reply [flat|nested] 7+ messages in thread
