Implement hash intrinsic #60
Comments

"cmp" actually doesn't need to be an intrinsic. The "<" operator should be sufficient. |

We discussed this at some length earlier in the year when considering equality operators, and I think at the time we settled on having two variants. The "operator symbols" variants (<, == and such) we decided to make "shallow", only-slot-comparing, memcmp-like, not-following-boxes; whereas we were going to make "cmp" a library function (only defined on pure, i.e. acyclic, values) that does deep comparison. The rationale was that we wanted to make the operator cases "most like machine operations", and also that (given a deep-compare operator is much easier to specify on acyclic structures) we didn't want == to only work on immutable types, as that would be too surprising. I suppose we could revisit this argument. |

The compare intrinsic is a dupe of issue #40, so I'll make this one about hash. |

Currently, when building with `build-std`, some library build scripts check properties of the target by inspecting the target triple at `env::TARGET`, which is simply set to the filename of the JSON file when using JSON target files. This patch alters these build scripts to use `env::CARGO_CFG_*` to fetch target information instead, allowing JSON target files describing platforms without `restricted_std` to build correctly when using `-Z build-std`. Fixes wg-cargo-std-aware/rust-lang#60.

"hash" and "cmp" intrinsics need to be implemented (most likely with the
native "intrinsic" modsyntax?)The text was updated successfully, but these errors were encountered:
