[LLVMdev] More questions about non_lazy_ptr
...point map. Here's what the code looks like in IR: %init = invoke {} @GC_init(i32* getelementptr inbounds ([0 x i32]* @gc_safepoint_map, i32 0, i32 0)) to label %nounwind unwind label %catch When lowered to assembly, the code looks like this on OS X: Ltmp426: movl L_gc_safepoint_map$non_lazy_ptr, %eax movl %eax, (%esp) calll _GC_init (and later on in the same file): L_gc_safepoint_map$non_lazy_ptr: .indirect_symbol _gc_safepoint_map .long 0 This looks correct to me - it's dereferencing the non_lazy_ptr version...

[LLVMdev] non_lazy_ptr question
...eing passed to an external function. (BTW, gc_safepoint_map is the map of all of the stack offsets containing pointers, indexed by the program counter address of the safe point. It's generated by a custom linker pass.) However, the code that is being generated looks like this: movl L_gc_safepoint_map$non_lazy_ptr, %eax movl %eax, (%esp) call _GC_init In other words, it's passing the 'non_lazy_ptr' version of the symbol directly to GC_init, without dereferencing it. This makes the code go boom. OK, so my question is: - Where exactly would this dereference...
