Hi!
While working on the multiversioning patch I've just posted,
I've noticed that on say:
void foo ();
void foo () __attribute__((target ("avx")));
void foo () __attribute__((target ("default")));
__attribute__((target ("default"))) void foo ()
{
}
__attribute__((target ("avx"))) void foo ()
{
}
void (*fn) () = foo;
we leak memory, because init_reload is called several times (due to target
attribute) and it never destroys reload_obstack already created before
initializing a new one. Fixed by initializing it just once.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* reload1.c (init_reload): Only initialize reload_obstack
during the first call.
