* MSan: blacklist a benign uninit in zlib.earthdok2014-12-181-1/+4

* Reland "Integrate SIMD optimisations for zlib"robert.bradford2014-11-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This version uses a "pthread_once" implementation, using Windows synchronisation primitives, imported from tcmalloc. Previous CLs: https://codereview.chromium.org/677713002/ https://codereview.chromium.org/552123005 This version of the CL also runs fine on Windows Server 2003. These optimisations have been published on zlib mailing list and at https://github.com/jtkukunas/zlib/ This change merges the following optimisation patches: - "For x86, add CPUID check." - "Adds SSE2 optimized hash shifting to fill_window." - "add SSE4.2 optimized hash function" - "add PCLMULQDQ optimized CRC folding" From Jim Kukunas <james.t.kukunas@linux.intel.com>; and adapts them to the current zlib version in Chromium. The optimisations are enabled at runtime if all the necessary CPU features are present. As the optimisations require extra cflags to enable the compiler to use the instructions the optimisations are held in their own static library with a stub implementation to allow linking on other platforms. TEST=net_unittests(GZipUnitTest) passes, Chrome functions and performance improvement seen on RoboHornet benchmark on Linux Desktop BUG=401517 Review URL: https://codereview.chromium.org/678423002 Cr-Commit-Position: refs/heads/master@{#302799}

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reland adds an MSan suppression entry to work around gaps in MSan's support for some of the intrinsics this patch uses. This version also inlines the insert_string_sse function as it uses inline assembly and therefore does not need to be in the static library. Original CL: https://codereview.chromium.org/552123005 These optimisations have been published on zlib mailing list and at https://github.com/jtkukunas/zlib/ This change merges the following optimisation patches: - "For x86, add CPUID check." - "Adds SSE2 optimized hash shifting to fill_window." - "add SSE4.2 optimized hash function" - "add PCLMULQDQ optimized CRC folding" From Jim Kukunas <james.t.kukunas@linux.intel.com>; and adapts them to the current zlib version in Chromium.
