Okay, let's just remove the "??" modifier from the constraint.
Thanks for your patience, explanations, and work on this, Vlad.
Thanks, David.
Committed as rev. 205765.
I'd like to work more on LRA for power. If you find any issue with LRA
generated code performance, it could help me a lot.
I know you are busy with power8 stuff but if you see some LRA generated
code examples can be improved, please let me know.
I'd like to work on spilling general regs into VSX regs too as it is
done for intel x86-64 (spilling into SSE). I guess it would help power8
performance. I am going to start this work when i have access to
power8. Although I should say the LRA code for this is not good right
now - there are few opportunities for spilling into SSE on x86-64. So
probably, I rewrite this code in LRA.
