[Bug rtl-optimization/25505] [4.0/4.1/4.2 Regression] gcc uses way too much stack space for this code

[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2005-12-20 21:44 -------
Small testcase:
typedef struct a
{
  int f[1000];
} a;
a f(void);
int g(void)
{
  f();
  f();
}

----

Note that the C front-end has always produced bad stack usage.
