Fixes a minor unused variable warning reported by Kernel test # robot [0]. # # 2. Improves the reported code bloat (-88KB / 374KB) [1] by outlining # some functions that are unlikely to be used in performance # sensitive workloads. # # 3. Fixes the reported excess stack usage on parisc [2] by removing # -O3 from zstd's compilation flags. -O3 triggered bugs in the # hppa-linux-gnu gcc-8 compiler. -O2 performance is acceptable: # neutral compression, about -1% decompression speed. We also reduce # code bloat (-105KB / 374KB). # # After this our code bloat is cut from 374KB to 105KB with gcc-11. If # we wanted to cut the remaining 105KB we'd likely have to trade # signicant performance, so I want to say that this is enough for now. # # We should be able to get further gains without sacrificing speed, but # that will take some significant optimization effort, and isn't # suitable for a quick fix. I've opened an upstream issue [3] to track # the code size, and try to avoid future regressions, and improve it in # the long term" # # Link: https://lore.kernel.org/linux-mm/202111120312.833wII4i-lkp@intel.com/T/ [0] # Link: https://lkml.org/lkml/2021/11/15/710 [1] # Link: https://lkml.org/lkml/2021/11/14/189 [2] # Link: https://github.com/facebook/zstd/issues/2867 [3] # Link: https://lore.kernel.org/r/20211117014949.1169186-1-nickrterrell@gmail.com/ # Link: https://lore.kernel.org/r/20211117201459.1194876-1-nickrterrell@gmail.com/ # # * tag 'zstd-for-linus-5.16-rc1' of git://github.com/terrelln/linux: # lib: zstd: Don't add -O3 to cflags # lib: zstd: Don't inline functions in zstd_opt.c # lib: zstd: Fix unused variable warning # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 4c388a8e740d3235a194f330c8ef327deef710f6 # < make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- allmodconfig # < make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig # make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- In file included from /kisskb/src/include/linux/string.h:253, from /kisskb/src/include/linux/bitmap.h:10, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/mm_types_task.h:14, from /kisskb/src/include/linux/mm_types.h:5, from /kisskb/src/include/linux/page-flags.h:13, from /kisskb/src/arch/arm64/include/asm/mte.h:14, from /kisskb/src/arch/arm64/include/asm/pgtable.h:12, from /kisskb/src/include/linux/pgtable.h:6, from /kisskb/src/include/linux/kasan.h:29, from /kisskb/src/lib/test_kasan.c:10: In function 'memcmp', inlined from 'kasan_memcmp' at /kisskb/src/lib/test_kasan.c:897:2: /kisskb/src/include/linux/fortify-string.h:263:25: error: call to '__read_overflow' declared with attribute error: detected read beyond size of object (1st parameter) 263 \| __read_overflow(); \| ^~~~~~~~~~~~~~~~~ In function 'memchr', inlined from 'kasan_memchr' at /kisskb/src/lib/test_kasan.c:872:2: /kisskb/src/include/linux/fortify-string.h:277:17: error: call to '__read_overflow' declared with attribute error: detected read beyond size of object (1st parameter) 277 \| __read_overflow(); \| ^~~~~~~~~~~~~~~~~ make[2]: * [/kisskb/src/scripts/Makefile.build:287: lib/test_kasan.o] Error 1 make[1]: * [/kisskb/src/Makefile:1846: lib] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_arm64-allmodconfig_arm64-gcc11 # Build took: 0:34:56.304793
