When outputing a non-lazy pointer for a stub, we may need to fill in the value
...
for the NLP because the object it's pointing to may be internal to the file.
This seems counter-intuitive, but bear with me. When we place the LSDA into the
TEXT section, the type info pointers need to be indirect and pc-rel. We
accomplish this by using NLPs. However, sometimes the types are local to the
file. GCC gets around this by not using a NLP in this case, but a "regular"
indirection like this:
GCC_except_tbl:
.long Lfoo-.
__ZTIA: @ This is local
...
Lfoo:
.long __ZTIA
LLVM prefers NLPs on Darwin. In fact, it's more optimal for load performance to
use them.
