hello,
I am writing a new backend for sparc with gcc-4.0.1, and I've
completely rewritten these backend files.
however, I have a vicious bug, and I can't find anything describing
that in the manuals
this is the code - pretty easy -
typedef struct tA
{
int x;
int y;
int z;
}A;
A a,b;
void foo(void)
{
a.x = 1;
a.y = 2;
a.z = 3;
//bug here
b = a;
// bug here
}
when copying structs the compiler seems to be stuck in an endless loop,
my question is to which RTL insns do the assignment struct operator is
converted, so I can easily fix this up.
if it doesn't concerning RTL, then how could I find out where does the
compiler is looping?
P.S.
when working with only two data types in the struct (int x, and int y)
this bug does not occur. perhaps it is some kind of alignment bug?
thanks.
