Rollup merge of #145690 - sayantn:integer-funnel-shift, r=tgross35

2025-09-04T05:43:21+00:00

Implement Integer funnel shifts Tracking issue: rust-lang/rust#145686 ACP: https://github.com/rust-lang/libs-team/issues/642 This implements funnel shifts on primitive integer types. Implements this for cg_llvm, with a fallback impl for everything else Thanks `@folkertdev` for the fixes and tests cc `@rust-lang/libs-api`

Add `funnel_sh{l,r}` functions and intrinsics

integer docs: remove extraneous text

2025-06-20T18:38:29+00:00

"Basic usage" implies there is an example that shows advanced usage, but these APIs are extra simple.

chore(doctest): Remove redundant blank lines

Auto merge of #138087 - tgross35:core-float-math, r=Amanieu

2025-05-17T19:31:39+00:00

Initial implementation of `core_float_math` Since [1], `compiler-builtins` makes a certain set of math symbols weakly available on all platforms. This means we can begin exposing some of the related functions in `core`, so begin this process here. It is not possible to provide inherent methods in both `core` and `std` while giving them different stability gates, so standalone functions are added instead. This provides a way to experiment with the functionality while unstable; once it is time to stabilize, they can be converted to inherent. For `f16` and `f128`, everything is unstable so we can move the inherent methods. The following are included to start: * floor * ceil * round * round_ties_even * trunc * fract * mul_add * div_euclid * rem_euclid * powi * sqrt * abs_sub * cbrt These mirror the set of functions that we have in `compiler-builtins` since [1], with the exception of `powi` that has been there longer. Details for each of the changes is in the commit messages.
