[LLVMdev] LLVM ERROR: ran out of registers during register allocation
Hello,
I'm getting the "LLVM ERROR: ran out of registers during register
allocation" error message for an out of tree target I'm developing. This is
happening for the following piece of C code:
struct ss
{
int a;
int b;
int c;
};
void loop(struct ss *x, struct ss **y, int z)
{
int i;
for (i=0; i<z; ++i)
{
x->c += y[i]->b;
}
}
The problem relies in
