When --enable-asan is provided to configure then build all user space components with fsanitize=address. For kernel support use the Linux KASAN feature instead. https://github.com/google/sanitizers/wiki/AddressSanitizer When using gcc version 4.8 any test case which intentionally generates a core dump will fail when using --enable-asan. The default behavior is to disable core dumps and only newer versions allow this behavior to be controled at run time with the ASAN_OPTIONS environment variable. Additionally, this patch includes some build system cleanup. * Rules.am updated to set the minimum AM_CFLAGS, AM_CPPFLAGS, and AM_LDFLAGS. Any additional flags should be added on a per-Makefile basic. The --enable-debug and --enable-asan options apply to all user space binaries and libraries. * Compiler checks consolidated in always-compiler-options.m4 and renamed for consistency. * -fstack-check compiler flag was removed, this functionality is provided by asan when configured with --enable-asan. * Split DEBUG_CFLAGS in to DEBUG_CFLAGS, DEBUG_CPPFLAGS, and DEBUG_LDFLAGS. * Moved default kernel build flags in to module/Makefile.in and split in to ZFS_MODULE_CFLAGS and ZFS_MODULE_CPPFLAGS. These flags are set with the standard ccflags-y kbuild mechanism. * -Wframe-larger-than checks applied only to binaries or libraries which include source files which are built in both user space and kernel space. This restriction is relaxed for user space only utilities. * -Wno-unused-but-set-variable applied only to libzfs and libzpool. The remaining warnings are the result of an ASSERT using a variable when is always declared. * -D_POSIX_PTHREAD_SEMANTICS and -D__EXTENSIONS__ dropped because they are Solaris specific and thus not needed. * Ensure $GDB is defined as gdb by default in zloop.sh.
