No, that should be the same for all

Is darwin the only target using TREE_TYPE rather than DECL_ARG_TYPE?
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70650
--- Comment #13 from Jason Merrill ---
The darwin problem is with an ipa-icf thunk trying to pass the parameter on
directly, which breaks because it's using the parameter's TREE_TYPE rather than
DECL_ARG_TYPE. expand_call handles this

In case it helps, with the proposed patch, the backtrace from fancy_abort in
the failing string-inst.cc compilation on darwin appears as...

This fixes the reduced testcase for me on sparc, does it fix bootstrap on the
various targets?

Seems sparc-solaris passes even for C the empty struct as a separate argument

Shorter testcase:
struct A {};
void
foo (struct A a, int b)
{
}
compiles with sparc-solaris C, but doesn't with C++.
