2023-09-21Auto merge of #116010 - RalfJung:more-typed-immediates, r=oli-obkbors-175/+181
interpret: more consistently use ImmTy in operators and casts The diff in src/tools/miri/src/shims/x86/sse2.rs should hopefully suffice to explain why this is nicer. :)
2023-09-21Rollup merge of #115972 - RalfJung:const-consistency, r=oli-obkGuillaume Gomez-2/+2
rename mir::Constant -> mir::ConstOperand, mir::ConstKind -> mir::Const Also, be more consistent with the `to/eval_bits` methods... we had some that take a type and some that take a size, and then sometimes the one that takes a type is called `bits_for_ty`. Turns out that `ty::Const`/`mir::ConstKind` carry their type with them, so we don't need to even pass the type to those `eval_bits` functions at all. However this is not properly consistent yet: in `ty` we have most of the methods on `ty::Const`, but in `mir` we have them on `mir::ConstKind`. And indeed those two types are the ones that correspond to each other. So `mir::ConstantKind` should actually be renamed to `mir::Const`. But what to do with `mir::Constant`? It carries around a span, that's really more like a constant operand that appears as a MIR operand... it's more suited for `syntax.rs` than `consts.rs`, but the bigger question is, which name should it get if we want to align the `mir` and `ty` types? `ConstOperand`? `ConstOp`? `Literal`? It's not a literal but it has a field called `literal` so it would at least be consistently wrong-ish... ``@oli-obk`` any ideas?

2023-09-18Auto merge of #115748 - RalfJung:post-mono, r=oli-obkbors-79/+32
move required_consts check to general post-mono-check function This factors some code that is common between the interpreter and the codegen backends into shared helper functions. Also as a side-effect the interpreter now uses the same `eval` functions as everyone else to get the evaluated MIR constants. Also this is in preparation for another post-mono check that will be needed for (the current hackfix for) https://github.com/rust-lang/rust/issues/115709: ensuring that all locals are dynamically sized. I didn't expect this to change diagnostics, but it's just cycle errors that change. r? `@oli-obk`

Read from non-scalar constants and statics in dataflow const-prop DataflowConstProp is designed to handle scalar values. When MIR features an assignment from a non-scalar constant, we need to manually decompose it into the custom state space. This PR tweaks interpreter callbacks to allow reusing `eval_mir_constant` without having a stack frame to get a span from. r? `@oli-obk` cc `@jachris`
