Requires the use of clang, and link-time optimizations Changes in v3: - clang 11+ warnings are now handled directly at the source, instead of disabling specific warnings for the whole code. Some more work may be needed here to polish the patch, I would kindly ask for a review from the corresponding maintainers - Remove configure-time checks for toolchain compatibility with LTO. - the decorator to disable cfi checks on functions has been renamed and moved to include/qemu/compiler.h - configure-time checks for cfi support and dependencies has been moved from configure to meson Link to v2: https://www.mail-archive.com/qemu-devel@nongnu.org/msg753675.html Link to v1: https://www.mail-archive.com/qemu-devel@nongnu.org/msg718786.html Daniele Buono (9): fuzz: Make fork_fuzz.ld compatible with LLVM's LLD s390x: fix clang 11 warnings in cpu_models.c hw/usb: reorder fields in UASStatus s390x: Avoid variable size warning in ipl.h scsi: fix overflow in scsi_disk_new_request_dump configure,meson: add option to enable LTO cfi: Initial support for cfi-icall in QEMU check-block: enable iotests with cfi-icall configure/meson: support Control-Flow Integrity accel/tcg/cpu-exec.c | 11 +++++++++ configure | 26 ++++++++++++++++++++ hw/s390x/ipl.h | 4 +-- hw/scsi/scsi-disk.c | 4 +++ hw/usb/dev-uas.c | 2 +- include/qemu/compiler.h | 12 +++++++++ meson.build | 46 +++++++++++++++++++++++++++++++++++ meson_options.txt | 4 +++ plugins/core.c | 37 ++++++++++++++++++++++++++++ plugins/loader.c | 7 ++++++ target/s390x/cpu_models.c | 8 +++--- tcg/tci.c | 7 ++++++ tests/check-block.sh | 18 ++++++++------ tests/qtest/fuzz/fork_fuzz.ld | 12 ++++++++- util/main-loop.c | 11 +++++++++ util/oslib-posix.c | 11 +++++++++ 16 files changed, 205 insertions(+), 15 deletions(-) -- 2.17.1
