--- Comment #10 from Yann Droneaud <yann at droneaud dot fr> ---
Some more snippets, generated with creduce:
-----------------8<--------------------
void a(long *);
int b(void);
void c(void);
long d(void) {
static __thread long e;
a(&e);
if (b())
c();
return e;
}
------------------8<--------------------
int a(void);
void b(long *);
void c(void) {
static __thread long d;
if (d || a())
d = 0;
b(&d);
}
------------------8<--------------------
void a(int *);
int b(int *);
int c(void) {
static __thread int d;
a(&d);
while (b(&d));
return 0;
}
------------------8<--------------------
void b(int *);
int c(int *);
int d(void) {
static __thread int a;
if (a)
while (c(&a));
b(&a);
return 0;
}
------------------8<--------------------
int b(void);
void c(void);
void d(int *);
int e(void) {
static __thread int a[2];
d(a);
do {
d(a);
if (b())
c();
} while (a[0] && a[1]);
d(a);
return 0;
}
------------------8<--------------------
Those make gcc emits 2 or more calls to __tls_get_addr().
