Scott McMurray	454bca514a	Check CastKind::Transmute sizes in a better way ... Fixes #110005	2023-04-06 13:53:10 -07:00
Scott McMurray	9aa9a846b6	Allow transmutes to produce OperandValues instead of always using allocas ... LLVM can usually optimize these away, but especially for things like transmutes of newtypes it's silly to generate the `alloc`+`store`+`load` at all when it's actually a nop at LLVM level.	2023-04-04 18:44:29 -07:00
Scott McMurray	64cce5fc7d	Add CastKind::Transmute to MIR ... Updates `interpret`, `codegen_ssa`, and `codegen_cranelift` to consume the new cast instead of the intrinsic. Includes `CastTransmute` for custom MIR building, to be able to test the extra UB.	2023-03-22 15:15:41 -07:00
