Bug ID: 112487
Summary: GCC: 14: internal compiler error: in
setup_one_parameter, at tree-inline.cc:3565
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: 141242068 at smail dot nju.edu.cn
Target Milestone: ---
Compiler explorer: https://gcc.godbolt.org/z/fjErPvrvP
When compile this program with `gcc-14 -O1`, gcc crashes:
```
struct A { char i; };
struct B {
struct C *p;
struct A *q;
};
struct C { struct B a[1]; };
struct T { struct U *ptr; };
volatile struct T v;
void f1(volatile struct T v) { f2(v); }
void f2(volatile struct T *const v) { }
void bar() {
struct U *ptr;
f1(v);
}
```
The crash output pasted from compiler explorer:
```

<source>:10:32: warning: implicit declaration of function 'f2'; did you mean

--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's technically invalid code, we are passing an aggregate value 'v' (volatile
qualified) to a function with pointer type, so the assert
3561 /* If the value of argument is never used, don't care about
initializing
3562 it. */
3563 if (optimize && gimple_in_ssa_p (cfun) && !def && is_gimple_reg (p))
3564 {
3565 gcc_assert (!value || !TREE_SIDE_EFFECTS (value));
3566 return insert_init_debug_bind (id, bb, var, rhs, NULL);
fires. But when p is a register the argument can never have side-effects
unless
there's a gross type mismatch. We instead should refrain from adding a
debug bind when such type mismatch occurs and not assert.

middle-end/112487 - inline and parameter mismatch
When passing an aggregate to a implicitly declared function that's
later declared as receiving a register type we can run into a
sanity assert that cannot hold for such gross mismatches. Instead
of asserting avoid emitting a debug temp that's invalid.
PR middle-end/112487
* tree-inline.cc (setup_one_parameter): When the parameter
is unused only insert a debug bind when there's not a gross
mismatch in value and declared parameter type. Do not assert
there effectively isn't.
* gcc.dg/torture/pr112487.c: New testcase.
