https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87133 --- Comment #9 from Segher Boessenkool --- It's a different symptom, but sure, might be related. Somehow your toolchain thinks it is a newer ISA but not compliant to older ISAs :-/

on native target pats contains {scode = 1122058, icode =
CODE_FOR_fixuns_truncsfdi2}, on cross compiler not.
cross-compiler: (gdb) p sizeof(pats)
$2 = 4440
native:
(gdb) p sizeof(pats)
$15 = 5448
That said, isn't it similar to: PR86684?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87133 --- Comment #7 from Segher Boessenkool --- lang_hooks.types.type_for_mode can return NULL, but emit_library_call_value cannot handle that. Why it fails on a cross and not natively, I don't know... target bug is my guess.

In calls.c I see:
│4742 if (outmode != VOIDmode)
│4743{
│4744 tfom = lang_hooks.types.type_for_mode (outmode, 0);
>│4745 if (aggregate_value_p (tfom, 0))
(gdb) p tfom
$2 =
(gdb) p outmode
$3 = E_KFmode
Would it help?
