Synopsis: ICE in gen_nop_type during 2.4.17 ia64 kernel build
State-Changed-From-To: open->analyzed
State-Changed-By: jakub
State-Changed-When: Sat Mar 9 05:59:58 2002
State-Changed-Why:
Simplified into:
typedef struct { unsigned long a; unsigned int b, c; } A;
typedef struct { unsigned long a; A *b; int c; } B;
static inline unsigned int
bar (unsigned int x)
{
unsigned long r;
asm ("" : "=r" (r) : "0" (x));
return r >> 32;
}
int foo (B *x)
{
A *y;
y = x->b;
y->b = bar (x->c);
y->c = ({ unsigned int z = 1; (z << 24) | (z >> 24); });
}
