From 8c00f56fcaf60f42474ca277e86c95f55941aa0d Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 3 Dec 2025 14:04:21 +0000 Subject: [PATCH] tcg/tci: Disable -Wundef FFI_GO_CLOSURES warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since we build TCI with FFI (commit 22f15579fa1 "tcg: Build ffi data structures for helpers") we get on Darwin: In file included from ../../tcg/tci.c:22: In file included from include/tcg/helper-info.h:13: /Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk/usr/include/ffi/ffi.h:483:5: warning: 'FFI_GO_CLOSURES' is not defined, evaluates to 0 [-Wundef] 483 | #if FFI_GO_CLOSURES | ^ 1 warning generated. This was fixed in upstream libffi in 2023, but not backported to MacOSX. Simply disable the warning locally.
