The check for coalescing a virtual register to a physical register, e.g.

cl = EXTRACT_SUBREG reg1024, 1, is overly conservative. It should check
for overlaps of vr's live interval with the super registers of the
physical register (ECX in this case) and let JoinIntervals() handle checking
the coalescing feasibility against the physical register (cl in this case).

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.
