Of course the code does not even give a sub register:
(insn 13 12 15 0 pr15286.c:9 (set (reg:DI 126)
(fix:DI (reg:DF 124))) 216 {fix_truncdfdi2} (insn_list 12 (nil))
(expr_list:REG_DEAD (reg:DF 124)
(nil)))
I cannot think of why the subregister is comming up in the first place.
But then again it could be this Apple LOCAL patch which is causing it:
- /* APPLE LOCAL assign_stack_local_with_alias is used instead of
- assign_stack_temp to get better scheduling, at the cost of some
- stack space. */
- rtx mem = assign_stack_local_with_alias (DImode, GET_MODE_SIZE (DImode),
- GET_MODE_ALIGNMENT (DImode));
+ rtx mem = assign_stack_temp (DImode, GET_MODE_SIZE (DImode), 0);
But then again we cannot test with a testcase which ICEs. I cannot think of any reason why there is a
sub register there at all. I think you need to figure out where the sub register is coming from and then
reduce the testcase around that.
