LLVM removed the size parameter from the lifetime format.
Tolerate not having that size parameter.
Auto merge of #143860 - scottmcm:transmute-always-rvalue, r=WaffleLapkin2025-07-26T22:45:18+00:00borsbors@rust-lang.org2025-07-26T22:45:18+00:00urn:sha1:283a0746a244a88503fed61844f44df925ccdbb6
Let `codegen_transmute_operand` just handle everything
When combined with rust-lang/rust#143720, this means `rvalue_creates_operand` can just return `true` for *every* `Rvalue`. (A future PR could consider removing it, though just letting it optimize out is fine for now.)
It's nicer anyway, IMHO, because it avoids needing the layout checks to be consistent in the two places, and thus is an overall reduction in code. Plus it's a more helpful building block when used in other places this way.
(TBH, it probably would have been better to have it this way the whole time, but I clearly didn't understand `rvalue_creates_operand` when I originally wrote rust-lang/rust#109843.)
Don't emit two `assume`s in transmutes when one is a subset of the other2025-07-23T16:16:32+00:00Scott McMurrayscottmcm@users.noreply.github.com2025-07-20T07:17:22+00:00urn:sha1:a93a9aa2d57564660b2c28e5c1cdda7943989f17
For example, transmuting between `bool` and `Ordering` doesn't need two `assume`s because one range is a superset of the other.
Multiple are still used for things like `char` <-> `NonZero<u32>`, which overlap but where neither fully contains the other.
