Clean up CMake header and type checks. Unused macros: HAVE_DLFCN_H, HAVE_INTTYPES_H, HAVE_MEMORY_H, HAVE_STDLIB_H, HAVE_STRINGS_H, HAVE_STRING_H, HAVE_SYS_BYTESWAP_H, HAVE_SYS_STAT_H, HAVE_SYS_TYPES_H, HAVE_UNISTD_H. Used but never set macros: HAVE_LIBLZF, HAVE_LIBQUICKLZ. These only gate conditional includes. The code that takes advantage of them was removed. Unused types: ssize_t. The testing code uses HAVE_FUNC_MMAP, which was not wired in the CMake build, causing a whole test to be skipped.

/* Define to 1 if the compiler supports __attribute__((always_inline)). */
Migrate feature detection macro checks from #ifdef to #if. The #if predicate evaluates to false if the macro is undefined, or defined to 0. #ifdef (and its synonym #if defined) evaluates to false only if the macro is undefined. The new setup allows differentiating between setting a macro to 0 (to express that the capability definitely does not exist / should not be used) and leaving a macro undefined (to express not knowing whether a capability exists / not caring if a capability is used).

Add unistd.h checks back to the CMake build. getpagesize(), as well as its POSIX.2001 replacement sysconf(_SC_PAGESIZE), is defined in <unistd.h>. On Linux and OS X, including <sys/mman.h> is sufficient to get a definition for getpagesize(). However, this is not true for the Android NDK. This CL brings back the HAVE_UNISTD_H definition and its associated header check. This also adds a HAVE_FUNC_SYSCONF definition, which checks for the presence of sysconf(). The definition can be used later to replace getpagesize() with sysconf().

Fix Visual Studio build. Commit 8f469d97e2ccbd87e5c00d25b1969daebfbfa350 introduced SSSE3 fast paths that are gated by __SSE3__ macro checks and the <x86intrin.h> header, neither of which exists in Visual Studio. This commit adds logic for detecting SSSE3 compiler support that works for all compilers supported by the open source release. The commit also replaces the header with <tmmintrin.h>, which only defines intrinsics supported by SSSE3 and below. This should help flag any use of SIMD instructions that require more advanced SSE support, so the uses can be gated by checks that also work in the open source release. Last, this commit requires C++11 support for the open source build. This is needed by the alignas specifier, which was also introduced in commit 8f469d97e2ccbd87e5c00d25b1969daebfbfa350.

Improve the speed of hashing in zippy compression. This change replaces the hashing function used during compression with one that is roughly as good but faster. This speeds up compression by two to a few percent on the Intel-, AMD-, and Arm-based machines we tested. The amount of compression is roughly unchanged. PiperOrigin-RevId: 485960303

Wrap BMI2 instruction usage in support checks. A previous version of this was submitted and rolled back due to breakage -- an attempt to accommodate Visual Studio resulted in compiler errors on GCC/Clang with -mavx2 but without -mbmi2. This version makes the BMI2 support check more strict, to avoid the errors. A previous CL introduced _bzhi_u32 (part of Intel's BMI2 instruction set, released in Haswell) gated by a check for the __BMI2__ preprocessor macro. This works for Clang and GCC, but does not work on Visual Studio, and may not work on other compilers. This CL plumbs the BMI2 support checks through the CMake configuration used by the open source build. It also replaces the <x86intrin.h> header, which does not exist on Visual Studio, with the more scoped headers <tmmintrin.h> (for SSSE3) and <immintrin.h> (for BMI2/AVX2). Asides from fixing the open source build, the more scoped headers make it slightly less likely that newer intrinsics will creep in without proper gating.

/* Define to 1 if your processor stores words with the most significant byte
first (like Motorola and SPARC, unlike Intel and VAX). */
Migrate feature detection macro checks from #ifdef to #if. The #if predicate evaluates to false if the macro is undefined, or defined to 0. #ifdef (and its synonym #if defined) evaluates to false only if the macro is undefined. The new setup allows differentiating between setting a macro to 0 (to express that the capability definitely does not exist / should not be used) and leaving a macro undefined (to express not knowing whether a capability exists / not caring if a capability is used).

#cmakedefine01 SNAPPY_IS_BIG_ENDIAN
Provide a CMakeLists.txt. This lands https://github.com/google/snappy/pull/29
2017-04-26 11:24:58 +00:00
Clean up CMake header and type checks. Unused macros: HAVE_DLFCN_H, HAVE_INTTYPES_H, HAVE_MEMORY_H, HAVE_STDLIB_H, HAVE_STRINGS_H, HAVE_STRING_H, HAVE_SYS_BYTESWAP_H, HAVE_SYS_STAT_H, HAVE_SYS_TYPES_H, HAVE_UNISTD_H. Used but never set macros: HAVE_LIBLZF, HAVE_LIBQUICKLZ. These only gate conditional includes. The code that takes advantage of them was removed. Unused types: ssize_t. The testing code uses HAVE_FUNC_MMAP, which was not wired in the CMake build, causing a whole test to be skipped.
