>From e36a7daae2d267f375b142a84c697429ce3fad3e Mon Sep 17 00:00:00 2001 From: Tomohiro Kashiwada <kikair...@gmail.com> Date: Fri, 18 Jul 2025 06:16:08 +0900 Subject: [PATCH] [Support/BLAKE3] quick fix for Cygwin build (#148635) BLAKE3 1.8.2 ( imported in d2ad63a193216d008c8161879a59c5f42e0125cc ) fails to build for the Cygwin target. see: https://github.com/BLAKE3-team/BLAKE3/issues/494 As a temporary workaround, add `&& !defined(__CYGWIN__)` to BLAKE3 locally. resolves https://github.com/llvm/llvm-project/issues/148365 (cherry picked from commit 8de61eb01c9752f0488ed8b52d01fe3d0873ff6c) --- llvm/lib/Support/BLAKE3/blake3_dispatch.c | 2 +- llvm/lib/Support/BLAKE3/blake3_impl.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/llvm/lib/Support/BLAKE3/blake3_dispatch.c b/llvm/lib/Support/BLAKE3/blake3_dispatch.c index d00580fe35195..19918aa708b2f 100644 --- a/llvm/lib/Support/BLAKE3/blake3_dispatch.c +++ b/llvm/lib/Support/BLAKE3/blake3_dispatch.c @@ -236,7 +236,7 @@ void blake3_xof_many(const uint32_t cv[8], #if defined(IS_X86) const enum cpu_feature features = get_cpu_features(); MAYBE_UNUSED(features); -#if !defined(_WIN32) && !defined(BLAKE3_NO_AVX512) +#if !defined(_WIN32) && !defined(__CYGWIN__) && !defined(BLAKE3_NO_AVX512) if (features & AVX512VL) { blake3_xof_many_avx512(cv, block, block_len, counter, flags, out, outblocks); return; diff --git a/llvm/lib/Support/BLAKE3/blake3_impl.h b/llvm/lib/Support/BLAKE3/blake3_impl.h index deed079e468a5..dd71e729f208f 100644 --- a/llvm/lib/Support/BLAKE3/blake3_impl.h +++ b/llvm/lib/Support/BLAKE3/blake3_impl.h @@ -324,7 +324,7 @@ void blake3_hash_many_avx512(const uint8_t *const *inputs, size_t num_inputs, uint8_t flags, uint8_t flags_start, uint8_t flags_end, uint8_t *out); -#if !defined(_WIN32) +#if !defined(_WIN32) && !defined(__CYGWIN__) LLVM_LIBRARY_VISIBILITY void blake3_xof_many_avx512(const uint32_t cv[8], const uint8_t block[BLAKE3_BLOCK_LEN], _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
