For now, it was only possible to build plugins using GCC on Windows. However, windows-aarch64 only supports Clang. This biggest roadblock was to get rid of gcc_struct attribute, which is not supported by Clang. After investigation, we proved it was safe to drop it.
Built and tested on Windows (all msys env)/Linux/MacOS for x86_64 and aarch64 hosts. v1 contained warning fixes and various bits that have been upstreamed already. The only bits left in this series are the gcc_struct removal, and fixing the plugins build with clang. This series is for 10.0, as we decided to not include the gcc_struct removal is 9.2 release. v1: https://patchew.org/QEMU/20241031040426.772604-1-pierrick.bouv...@linaro.org/ v2: - drop attribute gcc_struct instead of using -mno-ms-bitfields option - add a section about bitfields in documentation v3: - explain why gcc_struct attribute matters in packed structs in commit message - reword the bitfields documentation with suggestions given Pierrick Bouvier (3): win32: remove usage of attribute gcc_struct docs/devel/style: add a section about bitfield, and disallow them for packed structures plugins: enable linking with clang/lld docs/devel/style.rst | 20 +++++++++++++++++++ meson.build | 6 +++--- include/qemu/compiler.h | 7 +------ scripts/cocci-macro-file.h | 6 +----- subprojects/libvhost-user/libvhost-user.h | 6 +----- contrib/plugins/meson.build | 2 +- plugins/meson.build | 24 +++++++++++++++++++---- tests/tcg/plugins/meson.build | 3 +-- 8 files changed, 48 insertions(+), 26 deletions(-) -- 2.39.5
