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. All patches are now reviewed, so this series can be pulled. I'll report that to MSYS2 too, so we can enable clang environments for QEMU. 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 v4: - edit for bitfields doc requested by Philippe 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
