[LLVMdev] Marking *some* pointers for gc

[Ramkumar Ramachandra]

Hi,

I just found out that it's not practical to mark only some pointers
for GC. Consider:

%a = i8 addrspace(1)* malloc(...)
%b = i8* alloca(...)

The issue then becomes that routine functions declared:

declare i1 foo(i8 addrspace(1)*)

have a choice of accepting either gc'able or non-gc'able pointers. Is
there no way to have a reasonable mix of both?
