For Darwin / x86_64, override -relocation-model=static to pic if the output is assembly since Darwin assembler does not really support -static codeine.
...
I view this as a temporary workaround until the assembler / linker changes.

If there is a def of a super-register followed by a use of a sub-register, do *not* add an implicit def of the sub-register. e.g.

EAX = ..., AX<imp-def>

This creates a double-def. Apparently this used to be necessary but is no longer needed.

Make the implicit inputs and outputs of target-independent
...
ADDC/ADDE use MVT::i1 (later, whatever it gets legalized to)
instead of MVT::Flag. Remove CARRY_FALSE in favor of 0; adjust
all target-independent code to use this format.
Most targets will still produce a Flag-setting target-dependent
version when selection is done. X86 is converted to use i32
instead, which means TableGen needs to produce different code
in xxxGenDAGISel.inc. This keys off the new supportsHasI1 bit
in xxxInstrInfo, currently set only for X86; in principle this
is temporary and should go away when all other targets have
been converted. All relevant X86 instruction patterns are
modified to represent setting and using EFLAGS explicitly. The
same can be done on other targets.
The immediate behavior change is that an ADC/ADD pair are no
longer tightly coupled in the X86 scheduler; they can be
separated by instructions that don't clobber the flags (MOV).
I will soon add some peephole optimizations based on using
other instructions that set the flags to feed into ADC.
