Hi, I am trying to implement a simple load 8 bytes instruction. I tried to use movdi so that it would allocate two sequential registers for the load. It starts well but in pass subreg1 the insns are decomposed and all DI operands are replaced with SI.
I understand that this is a desireable optimzation but then the load is done using two load 4 bytes instructions. Does anybody has any idea what should I do? Thanks.
