Hi, This is a series that improves a bit the build system, and introduces ASAN/UBSan by default when --enable-debug. Then it fixes a few leaks that occur during make check: common and x86_64 target tests are leak free after this series. The other targets will need some work to fix the leaks & warnings.
v3: - add ubsan too with --enable-debug, since it is recommended and has low runtime cost - add a patch "compile with -Og or -O1 when --enable-debug", suggested by Paolo - add 2 new fixes to pass full make check with asan/ubsan - modify docker tests to run --enable-debug & asan with new test-debug - add some r-b/a-b tags v2: - simplify "build-sys: silence make by default or V=0": make it a oneliner MAKEFLAGS, use --quiet. - document print-VAR rule in docs/devel/build-system.txt - fix ASAN coroutine instrumentation failure - should fix builds on gcc 4.4.7 (centos 6) - new coroutine test leak fix - add some r-b tags Marc-André Lureau (18): build-sys: fix qemu-ga -pthread linking build-sys: silence make by default or V=0 build-sys: add a rule to print a variable build-sys: compile with -Og or -O1 when --enable-debug tests/docker: add some sanitizers to fedora dockerfile tests/docker: add test-debug build-sys: add some sanitizers when --enable-debug if possible tests: fix check-qobject leak vl: fix direct firmware directories leak readline: add a free function tests: fix migration-test leak crypto: fix stack-buffer-overflow error qemu-config: fix leak in query-command-line-options tests: fix qmp-test leak ucontext: annotate coroutine stack for ASAN tests: fix coroutine leak in /basic/entered mips: fix potential fopen(NULL,...) disas/s390: fix global-buffer-overflow include/qemu/compiler.h | 4 +++ include/qemu/readline.h | 1 + crypto/ivgen-essiv.c | 2 +- disas/s390.c | 16 +++++------- hw/nvram/ds1225y.c | 4 +-- monitor.c | 2 +- tests/check-qobject.c | 2 ++ tests/migration-test.c | 3 ++- tests/qmp-test.c | 3 ++- tests/test-coroutine.c | 1 - util/coroutine-ucontext.c | 46 ++++++++++++++++++++++++++++++++++ util/qemu-config.c | 3 ++- util/readline.c | 18 ++++++++++++- vl.c | 9 ++++--- Makefile | 7 ++++-- configure | 23 +++++++++++++++-- docs/devel/build-system.txt | 13 ++++++++++ rules.mak | 2 ++ tests/docker/dockerfiles/fedora.docker | 4 +-- tests/docker/test-clang | 2 +- tests/docker/test-debug | 26 +++++++++++++++++++ tests/docker/test-mingw | 2 -- 22 files changed, 162 insertions(+), 31 deletions(-) create mode 100755 tests/docker/test-debug -- 2.15.1.355.g36791d7216
