Implement the "Reinterpret casts" section of the RISC-V P extension intrinsic spec in `riscv_packed_simd.h`. The 82 `__riscv_preinterpret_<from>_<to>` intrinsics provide bit-pattern-preserving conversions between packed types and equal-width scalars, and between equal-width packed types. They generate no instructions; each is a `__builtin_bit_cast`. Tests cover every intrinsic on both RV32 and RV64. >From 07cd32d02393c05a60032c23213bfc835d9d9432 Mon Sep 17 00:00:00 2001 From: SiHuaN <[email protected]> Date: Fri, 17 Jul 2026 04:17:00 +0000 Subject: [PATCH] [Clang][RISCV] Add P extension reinterpret cast intrinsics Implement the Reinterpret casts section of the P extension intrinsic spec in riscv_packed_simd.h. These 82 __riscv_preinterpret_<from>_<to> intrinsics cover the packed<->scalar and packed<->packed conversions of equal width. They are bit-pattern-preserving and generate no instructions; each is a __builtin_bit_cast. --- clang/lib/Headers/riscv_packed_simd.h | 97 ++ clang/test/CodeGen/RISCV/rvp-intrinsics.c | 1074
