I'm trying to understand an assertion failure in reload1.c:8135.
In delete_output_reload(), I'm getting an assertion failure
in this code:
for (i1 = reg_equiv_alt_mem_list [REGNO (reg)]; i1; i1 = XEXP (i1, 1))
{
gcc_assert (!rtx_equal_p (XEXP (i1, 0), substed));
n_occurrences += count_occurrences (PATTERN (insn), XEXP (i1, 0), 0);
}
Sure enough, i1 matches substed.
reg_equiv_memory_loc[regno] (the source for substed) is the same as
reg_equiv_alt_mem_list[regno].
Why is this unexpected and what might cause it?
