bors	3d1eaf4b62	Auto merge of #94638 - erikdesjardins:noextranull, r=nagisa ... cleanup: remove unused ability to have LLVM null-terminate const strings (and the copied function in rustc_codegen_gcc) Noticed this while writing https://github.com/rust-lang/rust/pull/94450#issuecomment-1059687348. r? `@nagisa`	2022-03-07 02:07:36 +00:00
Nicholas Nethercote	4852291417	Introduce ConstAllocation. ... Currently some `Allocation`s are interned, some are not, and it's very hard to tell at a use point which is which. This commit introduces `ConstAllocation` for the known-interned ones, which makes the division much clearer. `ConstAllocation::inner()` is used to get the underlying `Allocation`. In some places it's natural to use an `Allocation`, in some it's natural to use a `ConstAllocation`, and in some places there's no clear choice. I've tried to make things look as nice as possible, while generally favouring `ConstAllocation`, which is the type that embodies more information. This does require quite a few calls to `inner()`. The commit also tweaks how `PartialOrd` works for `Interned`. The previous code was too clever by half, building on `T: Ord` to make the code shorter. That caused problems with deriving `PartialOrd` and `Ord` for `ConstAllocation`, so I changed it to build on `T: PartialOrd`, which is slightly more verbose but much more standard and avoided the problems.	2022-03-07 08:25:50 +11:00
