-------
Adding '<>' to the "=m" constraint fixes the testcase, but adding a single '>'
(or '<') results in an error for impossible constraints. This is caused by the
following snippet that was added to reload1.c:
switch (GET_CODE (XEXP (recog_data.operand[opno], 0)))
{
case PRE_INC:
case POST_INC:
case PRE_DEC:
case POST_DEC:
case PRE_MODIFY:
case POST_MODIFY:
if (strchr (recog_data.constraints[opno], '<') ==
NULL
|| strchr (recog_data.constraints[opno], '>')
== NULL)
return 0;
break;
Should the code be using '&&' instead of '||'?
