This series cleans up all usages of assert/g_assert who are supposed to stop execution of QEMU. We replace those by g_assert_not_reached(). It was suggested recently when cleaning codebase to build QEMU with gcc and tsan: https://lore.kernel.org/qemu-devel/54bb02a6-1b12-460a-97f6-3f478ef766c6@xxxxxxxxxx/. In more, cleanup useless break and return after g_assert_not_reached(); And finally, ensure with scripts/checkpatch.pl that we don't reintroduce (g_)assert(false) in the future. New commits (removing return) need review. Tested that it build warning free with gcc and clang. If a maintainer could pull the whole series, this would be much more easier than integrating various parts of it in different subsystems. Thanks! v3 - drop changes on .promela files - some changes were already merged v2 - align backslashes for some changes - add summary in all commits message - remove redundant comment v1 https://lore.kernel.org/qemu-devel/20240910221606.1817478-1-pierrick.bouvier@xxxxxxxxxx/T/#t Pierrick Bouvier (34): hw/acpi: replace assert(0) with g_assert_not_reached() hw/arm: replace assert(0) with g_assert_not_reached() hw/net: replace assert(0) with g_assert_not_reached() migration: replace assert(0) with g_assert_not_reached() qobject: replace assert(0) with g_assert_not_reached() target/ppc: replace assert(0) with g_assert_not_reached() block: replace assert(false) with g_assert_not_reached() hw/hyperv: replace assert(false) with g_assert_not_reached() hw/net: replace assert(false) with g_assert_not_reached() hw/nvme: replace assert(false) with g_assert_not_reached() hw/pci: replace assert(false) with g_assert_not_reached() hw/ppc: replace assert(false) with g_assert_not_reached() migration: replace assert(false) with g_assert_not_reached() target/i386/kvm: replace assert(false) with g_assert_not_reached() accel/tcg: remove break after g_assert_not_reached() block: remove break after g_assert_not_reached() hw/acpi: remove break after g_assert_not_reached() hw/net: remove break after g_assert_not_reached() hw/scsi: remove break after g_assert_not_reached() hw/tpm: remove break after g_assert_not_reached() target/arm: remove break after g_assert_not_reached() target/riscv: remove break after g_assert_not_reached() fpu: remove break after g_assert_not_reached() tcg/loongarch64: remove break after g_assert_not_reached() include/qemu: remove return after g_assert_not_reached() hw/hyperv: remove return after g_assert_not_reached() hw/net: remove return after g_assert_not_reached() hw/pci: remove return after g_assert_not_reached() hw/ppc: remove return after g_assert_not_reached() migration: remove return after g_assert_not_reached() qobject: remove return after g_assert_not_reached() qom: remove return after g_assert_not_reached() tests/qtest: remove return after g_assert_not_reached() scripts/checkpatch.pl: emit error when using assert(false) include/qemu/pmem.h | 1 - accel/tcg/plugin-gen.c | 1 - block/qcow2.c | 2 +- block/ssh.c | 1 - hw/acpi/aml-build.c | 3 +-- hw/arm/highbank.c | 2 +- hw/hyperv/hyperv_testdev.c | 7 +++---- hw/hyperv/vmbus.c | 15 ++++++--------- hw/net/e1000e_core.c | 4 +--- hw/net/i82596.c | 2 +- hw/net/igb_core.c | 4 +--- hw/net/net_rx_pkt.c | 3 +-- hw/net/vmxnet3.c | 1 - hw/nvme/ctrl.c | 8 ++++---- hw/pci/pci-stub.c | 6 ++---- hw/ppc/ppc.c | 1 - hw/ppc/spapr_events.c | 3 +-- hw/scsi/virtio-scsi.c | 1 - hw/tpm/tpm_spapr.c | 1 - migration/dirtyrate.c | 3 +-- migration/migration-hmp-cmds.c | 2 +- migration/postcopy-ram.c | 21 +++++++-------------- migration/ram.c | 8 +++----- qobject/qlit.c | 2 +- qobject/qnum.c | 12 ++++-------- qom/object.c | 1 - target/arm/hyp_gdbstub.c | 1 - target/i386/kvm/kvm.c | 4 ++-- target/ppc/dfp_helper.c | 8 ++++---- target/ppc/mmu_helper.c | 2 +- target/riscv/monitor.c | 1 - tests/qtest/acpi-utils.c | 1 - fpu/softfloat-parts.c.inc | 2 -- target/riscv/insn_trans/trans_rvv.c.inc | 2 -- tcg/loongarch64/tcg-target.c.inc | 1 - scripts/checkpatch.pl | 3 +++ 36 files changed, 50 insertions(+), 90 deletions(-) -- 2.39.5
