gcj used to perform an optimization which eliminated redundant class
initialization calls. For example, given the following example,
_Jv_InitClass(Foo) is called twice from Init.a() when it is only needed once:
class Foo
{
static int a;
static int b;
}
public class Init
{
int a()
{
return Foo.a + Foo.b;
}
}
This was done in expr.c build_class_init(), look for
LOCAL_CLASS_INITIALIZATION_FLAG. The optimization was turned off in tree-ssa
branch and needs to be updated to work with the gimplifier.
