Update the xor_blocks() prototypes so that the compiler understands that the inputs always refer to distinct regions of memory. This is implied by the existing implementations, as they use different granularities for the load/xor/store loops. With that, we can fix the ARM/Clang version, which refuses to SIMD vectorize otherwise, and throws a spurious warning related to the GCC version being incompatible. Changes since v3: - revert broken PPC argument rename - doing it fully results in too much pointless churn, and the 'inner' altivec routines are not strictly part of the xor_blocks API anyway Changes since v2: - fix arm64 build after rebase - name PPC argument names consistently - add Nick's acks and link tags Changes since v1: - fix PPC build - add Nathan's Tested-by Cc: Nick Desaulniers <ndesaulniers@xxxxxxxxxx> Cc: Nathan Chancellor <nathan@xxxxxxxxxx> Ard Biesheuvel (2): lib/xor: make xor prototypes more friendly to compiler vectorization crypto: arm/xor - make vectorized C code Clang-friendly arch/alpha/include/asm/xor.h | 53 ++++++++---- arch/arm/include/asm/xor.h | 42 ++++++---- arch/arm/lib/xor-neon.c | 12 +-- arch/arm64/include/asm/xor.h | 21 +++-- arch/arm64/lib/xor-neon.c | 46 +++++++---- arch/ia64/include/asm/xor.h | 21 +++-- arch/powerpc/include/asm/xor_altivec.h | 25 +++--- arch/powerpc/lib/xor_vmx.c | 28 ++++--- arch/powerpc/lib/xor_vmx.h | 27 ++++--- arch/powerpc/lib/xor_vmx_glue.c | 32 ++++---- arch/s390/lib/xor.c | 21 +++-- arch/sparc/include/asm/xor_32.h | 21 +++-- arch/sparc/include/asm/xor_64.h | 42 ++++++---- arch/x86/include/asm/xor.h | 42 ++++++---- arch/x86/include/asm/xor_32.h | 42 ++++++---- arch/x86/include/asm/xor_avx.h | 21 +++-- include/asm-generic/xor.h | 84 +++++++++++++------- include/linux/raid/xor.h | 21 +++-- 18 files changed, 384 insertions(+), 217 deletions(-) -- 2.30.2
