+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Ludovic Henry <git@ludovic.dev>
+Date: Fri, 25 Sep 2026 00:00:00 +0000
+Subject: [PATCH] Map riscv64 to a Linux build triplet for GMP
+
+BUILD_TRIPLET is handed to GMP's configure as --build, and only x86_64
+and aarch64 get a full "<cpu>-linux-gnu" triplet. On riscv64 it falls
+back to the bare CMAKE_HOST_SYSTEM_PROCESSOR, which GMP's config.sub
+canonicalises to "riscv64-unknown-none". libtool knows no dynamic linker
+for host_os "none", so GMP's configure answers "whether to build shared
+libraries... no" and produces only libgmp.a, while the default
+BUILD_SHARED_LIBS build links against deps/lib/libgmp.so.
+
+Give riscv64 the same treatment as aarch64. With riscv64-linux-gnu GMP
+still selects its mpn/riscv/64 assembly and builds libgmp.so.
+
+Upstream-Status: To upstream [not yet submitted; cmake/Helpers.cmake on cvc5 main still has no riscv64 branch]
