From: Marc-André Lureau <marcandre.lur...@redhat.com> Hi,
Depending on -Doptimization=<value>, GCC (14.2.1 here) produces different maybe-uninitialized warnings: - g: produces -Werror=maybe-uninitialized errors - 0: clean build - 1: produces -Werror=maybe-uninitialized errors - 2: clean build - 3: produces few -Werror=maybe-uninitialized errors - s: produces -Werror=maybe-uninitialized errors Most are false-positive, because prior LOCK_GUARD should guarantee an initialization path. Few of them are a bit trickier. Finally, I found a potential related memory leak. thanks v2: - rebased, dropped some patches - added some new patches with updated code-base and newer GCC - added s-o-b/a-b Marc-André Lureau (22): util/coroutine: fix -Werror=maybe-uninitialized false-positive util/timer: fix -Werror=maybe-uninitialized false-positive hw/qxl: fix -Werror=maybe-uninitialized false-positives nbd: fix -Werror=maybe-uninitialized false-positive block/mirror: fix -Werror=maybe-uninitialized false-positive block/mirror: fix -Werror=maybe-uninitialized false-positive block/stream: fix -Werror=maybe-uninitialized false-positives hw/ahci: fix -Werror=maybe-uninitialized false-positive hw/vhost-scsi: fix -Werror=maybe-uninitialized hw/sdhci: fix -Werror=maybe-uninitialized false-positive block/block-copy: fix -Werror=maybe-uninitialized false-positive migration: fix -Werror=maybe-uninitialized false-positives hw/virtio-blk: fix -Werror=maybe-uninitialized false-positive migration: fix -Werror=maybe-uninitialized false-positive linux-user/hppa: fix -Werror=maybe-uninitialized false-positive target/loongarch: fix -Werror=maybe-uninitialized false-positive tests: fix -Werror=maybe-uninitialized false-positive hw/virtio: fix -Werror=maybe-uninitialized false-positive block: fix -Werror=maybe-uninitialized false-positive qom/object: fix -Werror=maybe-uninitialized fsdep/9p: fix -Werror=maybe-uninitialized false-positive RFC: hw/virtio: a potential leak fix block/block-copy.c | 2 +- block/file-posix.c | 2 +- block/mirror.c | 8 ++++---- block/stream.c | 6 +++--- fsdev/9p-iov-marshal.c | 6 +++--- hw/block/virtio-blk.c | 2 +- hw/display/qxl.c | 4 ++-- hw/ide/ahci.c | 3 ++- hw/scsi/vhost-scsi.c | 2 +- hw/sd/sdhci.c | 2 +- hw/virtio/vhost-shadow-virtqueue.c | 6 ++++-- linux-user/hppa/cpu_loop.c | 10 +++++----- migration/dirtyrate.c | 4 ++-- migration/migration.c | 2 +- migration/ram.c | 2 +- nbd/client-connection.c | 2 +- qom/object.c | 5 ++++- target/loongarch/gdbstub.c | 26 ++++++++++++++------------ tests/unit/test-bdrv-drain.c | 2 +- tests/unit/test-block-iothread.c | 2 +- util/qemu-coroutine.c | 2 +- util/qemu-timer.c | 6 +++--- 22 files changed, 57 insertions(+), 49 deletions(-) -- 2.45.2.827.g557ae147e6
