Mr. krzysztof I have seen similar question asked by you on llvm group.
Could you please help me here to address this issue.

i am trying to construct a register of size 65536 bit by combining 2
registers of 32768 bits. both the 32768 bit registers are different so i
have to use the following method

let SubRegIndices = [sub_32768bit, sub_32768bit_hi], CoveredBySubRegs = 1 in

but i am getting following error..

error:Ran out of lanemask bits to represent subregister

now how to increase lanemask bits? what changes are required??

Kindly help.
