From: Marc-André Lureau <marcandre.lureau@redhat.com> Hi, Depending on -Doptimization=<value>, GCC (13.2.1 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 Marc-André Lureau (19): util/coroutine: fix -Werror=maybe-uninitialized false-positive util/timer: with -Werror=maybe-uninitialized false-positive hw/qxl: fix -Werror=maybe-uninitialized false-positives nbd: with -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 hw/rdma: fix -Werror=maybe-uninitialized false-positive migration/block: fix -Werror=maybe-uninitialized false-positive migration: fix -Werror=maybe-uninitialized false-positives hw/virtio-blk: fix -Werror=maybe-uninitialized false-positive plugins: fix -Werror=maybe-uninitialized false-positive migration: fix -Werror=maybe-uninitialized false-positive tests: fix -Werror=maybe-uninitialized hw/nvme: fix -Werror=maybe-uninitialized hw/virtio: fix -Werror=maybe-uninitialized RFC: hw/virtio: a potential leak fix block/mirror.c | 2 +- block/stream.c | 6 +++--- hw/block/virtio-blk.c | 2 +- hw/display/qxl.c | 4 ++-- hw/ide/ahci.c | 3 ++- hw/nvme/ctrl.c | 2 +- hw/rdma/rdma_backend.c | 2 +- hw/scsi/vhost-scsi.c | 2 +- hw/sd/sdhci.c | 2 +- hw/virtio/vhost-shadow-virtqueue.c | 6 ++++-- migration/block.c | 2 +- migration/dirtyrate.c | 4 ++-- migration/migration.c | 2 +- migration/ram.c | 2 +- nbd/client-connection.c | 2 +- plugins/loader.c | 2 +- tests/unit/test-bdrv-drain.c | 2 +- tests/unit/test-block-iothread.c | 2 +- util/qemu-coroutine.c | 2 +- util/qemu-timer.c | 6 +++--- 20 files changed, 30 insertions(+), 27 deletions(-)
