bd4b11cfa9 Initial support for multi-result patterns: 
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.

using it for live-in values etc.

b9a6798216 Sometimes a MI can define a register as well as defining a super-register at the 
same time. Do not mark the "smaller" def as dead.

7bc3969cea Add APInt interfaces to APFloat (allows directly 
access to bits).  Use them in place of float and
double interfaces where appropriate.
First bits of x86 long double constants handling 
(untested, probably does not work).

the underlying nested function.

4106f87b42 Two ParamAttrsVectors which differ by a permutation 
of their elements do not yield the same ParamAttrsList,
though they should.  On the other hand, everyone seems
to pass such vectors with elements ordered by increasing
index, so rather than sorting the elements simply assert
that the elements are ordered in this way.
