A small reproducer is: int *a[1024], b[1024]; void f1 (void) { for (int i = 0; i < 1024; i++) { int *p = &b[0]; a[i] = p + i; } } vect-126.c:18:1: internal compiler error: Segmentation fault 18 | } | ^ 0x111e61f crash_signal ../../gcc/toplev.cc:314 0xcfc91d mark_label_nuses ../../gcc/emit-rtl.cc:3755 0xcfc969 mark_label_nuses ../../gcc/emit-rtl.cc:3763 0xcfc969 mark_label_nuses ../../gcc/emit-rtl.cc:3763 0xcfc969 mark_label_nuses ../../gcc/emit-rtl.cc:3763 This happens after the splitter (define_insn_and_split "*single_widen_fma<mode>". At first glance it seems as if the insn sequence is corrupt as we're looking into a <nil> value but I haven't checked further. This is likely the same error that prevents several SPECfp testcases to build. Can investigate further tomorrow. ^ permalink raw reply [flat|nested] 5+ messages in thread
