Byte Type: Supporting Raw Data Copies in the LLVM IR
- bestouff 1y agoI wonder how this will work for Rust where bytes are u8 - will they special-case them ? That would look weird. Also there are some botched examples, e.g. : > define void @src(ptr %a, ptr %b) > { > %mem = alloca i8 > call void @llvm.memcpy(ptr %mem, ptr %a, i32 1) > call void @llvm.memcpy(ptr %a, ptr %mem, i32 1) > ret void > } The last %a should be a %b. But you can get the idea anyway.
- kobebrookskC3 1y agowouldn't byte in rust be more like MaybeUninit<u8>, to account for uninit and pointer fragments?
- bestouff 1y agoThat means MaybeUninit would not be library-only anymore, but would need some compiler help. But yes you're right.
- jojomodding 1y agoIt already has lots of "magic" semantics and never was just a library type
- jojomodding 1y agoYes.
