A gcc build from today (gcc version 4.4.0 20080924) gets an ICE on PowerPC when
building this (admittedly broken) code:
# gcc -m64 -O2 -c test.c
struct foo {
int a;
char lock;
};
struct foo *foo;
void testcase()
{
__sync_lock_test_and_set(&(foo->lock), 0);
}
It compiles if building 32bit. Even so, I wonder if gcc should warn when the
variable is incompatible with __sync_* builtins.
