; We used to misclassify inalloca as a static alloca in the inliner. This only
; arose with for alwaysinline functions, because the normal inliner refuses to
; inline such things.
; Generated using this C++ source:
; struct Foo {
; Foo();
; Foo(const Foo &o);
; ~Foo();
; int a;
; };
; __forceinline void h(Foo o) {}
; __forceinline void g() { h(Foo()); }
; void f() { g(); }
