try_inline should not recurse when edge is already inlined. The following
patch should fix the problem, I will benchmark it tonight
Index: ipa-inline.c

The #c6 patch doesn't make sense to me.
Two alternative testcases:
inline __attribute__ ((always_inline))
void A (void)
{
int i;
asm volatile ( : =m (i));
A ();
A ();
}
int
main ()
{
A ();
return 0;
}

Further testcases:
inline __attribute__((always_inline))
void A (void)
{
A ();
A ();
A ();
}
int
main ()
{
A ();
return 0;
}
and:
inline void A (void);
inline void B (void);
inline __attribute__

We should still optimize
static void bar(void) { foo (); }
inline void __attribute__((always_inline)) foo(void)
{
foo ();
bar ();
}
to
foo() { foo(); foo (); }
or similar cases, that is basically collapse

Confirmed.
here is one that fails with both the C and C++ front-ends:
inline __attribute__((always_inline)) void A(int *this1)
{
int this2;
int this3;
A(this2);
