SIMD implementation of vdev_raidz generate and reconstruct routines This is a new implementation of RAIDZ1/2/3 routines using x86_64 scalar, SSE, and AVX2 instruction sets. Included are 3 parity generation routines (P, PQ, and PQR) and 7 reconstruction routines, for all RAIDZ level. On module load, a quick benchmark of supported routines will select the fastest for each operation and they will be used at runtime. Original implementation is still present and can be selected via module parameter. Patch contains: - specialized gen/rec routines for all RAIDZ levels, - new scalar raidz implementation (unrolled), - two x86_64 SIMD implementations (SSE and AVX2 instructions sets), - fastest routines selected on module load (benchmark). - cmd/raidz_test - verify and benchmark all implementations - added raidz_test to the ZFS Test Suite New zfs module parameters: - zfs_vdev_raidz_impl (str): selects the implementation to use. On module load, the parameter will only accept first 3 options, and the other implementations can be set once module is finished loading. Possible values for this option are: "fastest" - use the fastest math available "original" - use the original raidz code "scalar" - new scalar impl "sse" - new SSE impl if available "avx2" - new AVX2 impl if available See contents of `/sys/module/zfs/parameters/zfs_vdev_raidz_impl` to get the list of supported values. If an implementation is not supported on the system, it will not be shown. Currently selected option is enclosed in `[]`.

include $(top_srcdir)/config/Rules.am
Support -fsanitize=address with --enable-asan 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.

Clean up lib dependencies libzutil is currently statically linked into libzfs, libzfs_core and libzpool. Avoid the unnecessary duplication by removing it from libzfs and libzpool, and adding libzfs_core to libzpool. Remove a few unnecessary dependencies: - libuutil from libzfs_core - libtirpc from libspl - keep only libcrypto in libzfs, as we don't use any functions from libssl - librt is only used for clock_gettime, however on modern systems that's in libc rather than librt. Add a configure check to see if we actually need librt - libdl from raidz_test Add a few missing dependencies: - zlib to libefi and libzfs - libuuid to zpool, and libuuid and libudev to zed - libnvpair uses assertions, so add assert.c to provide aok and libspl_assertf Sort the LDADD for programs so that libraries that satisfy dependencies come at the end rather than the beginning of the linker command line. Revamp the configure tests for libaries to use FIND_SYSTEM_LIBRARY instead. This can take advantage of pkg-config, and it also avoids polluting LIBS. List all the required dependencies in the pkgconfig files, and move the one for libzfs_core into the latter's directory. Install pkgconfig files in $(libdir)/pkgconfig on linux and $(prefix)/libdata/pkgconfig on FreeBSD, instead of /usr/share/pkgconfig, as the more correct location for library .pc files.
