Hello everyone.
I'm porting gcc to a new architecture and I'm allowing use of movdi instructions as the processor allows 8 byte loads. The processor however requires 8 byte loads and stores to be naturally aligned, yet gcc seems to be emitting loads and stores that are 4 byte aligned. How can I make sure that gcc will only emit 8 byte loads and stores if it knows the address, which can be in a register, is 8 byte aligned?
