Stabilize Ratified RISC-V Target Features #1476
Stabilize Ratified RISC-V Target Features #1476
Conversation
r? @Amanieu (rustbot has picked a reviewer for you, use r? to override) |
Could you open a PR for rust-lang/rust first which stabilizes the compiler-level feature names so that we can start a T-lang FCP on that? |

Do I need to request a separate FCP for this PR or is this also okay to merge if rust-lang/rust#116485 passes the FCP? |
The other FCP is sufficient. |

…features, r=Amanieu Stabilize Ratified RISC-V Target Features Stabilization PR for the ratified RISC-V target features. This stabilizes some of the target features tracked by rust-lang#44839. This is also a part of rust-lang#114544 and eventually needed for the RISC-V part of rust-lang/rfcs#3268. There is a similar PR for the the stdarch crate which can be found at rust-lang/stdarch#1476. This was briefly discussed on Zulip (https://rust-lang.zulipchat.com/#narrow/stream/250483-t-compiler.2Frisc-v/topic/Stabilization.20of.20RISC-V.20Target.20Features/near/394793704). Specifically, this PR stabilizes the: * Atomic Instructions (A) on v2.0 * Compressed Instructions (C) on v2.0 * ~Double-Precision Floating-Point (D) on v2.2~ * ~Embedded Base (E) (Given as `RV32E` / `RV64E`) on v2.0~ * ~Single-Precision Floating-Point (F) on v2.2~ * Integer Multiplication and Division (M) on v2.0 * ~Vector Operations (V) on v1.0~ * Bit Manipulations (B) on v1.0 listed as `zba`, `zbc`, `zbs` * Scalar Cryptography (Zk) v1.0.1 listed as `zk`, `zkn`, `zknd`, `zkne`, `zknh`, `zkr`, `zks`, `zksed`, `zksh`, `zkt`, `zbkb`, `zbkc` `zkbx` * ~Double-Precision Floating-Point in Integer Register (Zdinx) on v1.0~ * ~Half-Precision Floating-Point (Zfh) on v1.0~ * ~Minimal Half-Precision Floating-Point (Zfhmin) on v1.0~ * ~Single-Precision Floating-Point in Integer Register (Zfinx) on v1.0~ * ~Half-Precision Floating-Point in Integer Register (Zhinx) on v1.0~ * ~Minimal Half-Precision Floating-Point in Integer Register (Zhinxmin) on v1.0~ r? `@Amanieu`
