I'm trying to create new backend. Can anyone help with such question?
In a target there are 32 and 64-bit registers. I've made load/store 32-bit
values without difficulties. Now i'm doing 64-bit store into memory.
There is a direct 64bit store of register -> memory (i represented it in
TargetInstructionInfo.td) and wrote lowering for i64 Constant store.
The question is: does it need to do lowering for i64 register to memory
store or it should "find" this store in TargetInstructionInfo.td?
Thanks in advance.
