[LLVMdev] LLVM ERROR: ran out of registers during register allocation
...allocted if the addresses of both x and y[i] are
cross class copied to DREGS registers to temporarily store these values and
then when required copied back to the the register in PTR to access them in
memory.
Any help for a solution or a workaround will be greatly appreciated since
this problem is severily limiting the complexity of the programs that I can
currently compile.
Thanks.

Those are some severe constraints on register allocation, but it ought to be possible anyway.
You may wan't to investigate how RAGreedy::canEvictInterference() is behaving.
