2023-08-06	Add a new `compare_bytes` intrinsic instead of calling `memcmp` directly	Scott McMurray	-0/+34

2023-07-27	CHECK only for opaque ptr	Josh Stone	-2/+2

2023-07-27	Update the minimum external LLVM to 15	Josh Stone	-4/+0

2023-07-08	Always name the return place.	Camille GILLOT	-61/+57

2023-05-31	Add a distinct `OperandValue::ZeroSized` variant for ZSTs	Scott McMurray	-4/+71
	These tend to have special handling in a bunch of places anyway, so the variant helps remember that. And I think it's easier to grok than non-Scalar Aggregates sometimes being `Immediates` (like I got wrong and caused 109992). As a minor bonus, it means we don't need to generate poison LLVM values for them to pass around in `OperandValue::Immediate`s.
2023-04-27	Also use `mir::Offset` for pointer `add`	Scott McMurray	-0/+34

2023-04-22	Add `intrinsics::transmute_unchecked`	Scott McMurray	-33/+9
	This takes a whole 3 lines in `compiler/` since it lowers to `CastKind::Transmute` in MIR exactly the same as the existing `intrinsics::transmute` does, it just doesn't have the fancy checking in `hir_typeck`. Added to enable experimenting with the request in <https://github.com/rust-lang/rust/pull/106281#issuecomment-1496648190> and because the portable-simd folks might be interested for dependently-sized array-vector conversions. It also simplifies a couple places in `core`.
2023-04-13	`assume` value ranges in `transmute`	Scott McMurray	-4/+188
	Fixes #109958
2023-04-09	Handle not all immediates having `abi::Scalar`s	Scott McMurray	-1/+92

2023-04-06	Check `CastKind::Transmute` sizes in a better way	Scott McMurray	-1/+73
	Fixes #110005
2023-04-04	Allow `transmute`s to produce `OperandValue`s instead of always using `alloca`s	Scott McMurray	-23/+130
	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.
2023-03-22	Add `CastKind::Transmute` to MIR	Scott McMurray	-0/+196
	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.
2023-01-17	Add more codegen tests	Nilstrieb	-4/+5

2023-01-17	Put `noundef` on all scalars that don't allow uninit	Nilstrieb	-2/+2
	Previously, it was only put on scalars with range validity invariants like bool, was uninit was obviously invalid for those. Since then, we have normatively declared all uninit primitives to be undefined behavior and can therefore put `noundef` on them. The remaining concern was the `mem::uninitialized` function, which cause quite a lot of UB in the older parts of the ecosystem. This function now doesn't return uninit values anymore, making users of it safe from this change. The only real sources of UB where people could encounter uninit primitives are `MaybeUninit::uninit().assume_init()`, which has always be clear in the docs about being UB and from heap allocations (like reading from the spare capacity of a vec. This is hopefully rare enough to not break anything.
2023-01-11	Move /src/test to /tests	Albert Larsan	-0/+328
