Program received signal SIGSEGV, Segmentation fault. 0x00000000012f2e6b in can_native_interpret_type_p (type=<tree 0x0>) at ../../src/trunk/gcc/fold-const.c:8800 8800 switch (TREE_CODE (type)) 3049 if (!can_native_interpret_type_p (var_type)) 3050 { 3051 alt_type 3052 = lang_hooks.types.type_for_mode (TYPE_MODE (var_type), 3053 TYPE_UNSIGNED (var_type)); 3054 gcc_assert (can_native_interpret_type_p (alt_type)); 3055 } alt_type doesn't need to exist. TYPE_MODE is OImode here. Another issue will be that native_interpret_int refuses to interpret types bigger than 128bit. So using alt_type = build_nonstandard_integer_type (GET_MODE_BITSIZE (TYPE_MODE (var_type)), 1); will likely not help. But if we know we're using an integer type we can natively interpret ourselves. Note there's another hole with variable-size and SVE vector modes I think. I'm testing something. ^ permalink raw reply [flat|nested] 5+ messages in thread
