Sync TODO and comment processing with external repo.
Copybara transforms code slightly different than MOE. One example is the TODO username stripping where Copybara produces different results than MOE did. This change moves the Copybara versions of comments to the public repository. Note: These changes didn't originate in cl/247950252. PiperOrigin-RevId: 247950252 |

Update Travis CI configuration.
The Travis configuration: 1) Installs recent versions of clang and GCC. 2) Sets up the environment so that CMake picks up the installed compilers. Previously, the pre-installed clang compiler was used instead. 3) Requests a modern macOS image that has all the headers needed by GCC. The CL also removes now-unnecessary old workarounds from the Travis configuration. PiperOrigin-RevId: 245832795 |

Convert DCHECK to assert.
A previous CL introduced a use of DCHECK. The open source build does not support DCHECK, and this project uses assert() instead of DCHECK. |

Reduce the LeftShiftOverflows() table size.
A previous CL introduced LeftShiftOverflows(), which takes a uint32 input. However, the value it operates on is guaranteed to only have 8 bits set. This CL takes advantage of this restriction to reduce the size of the static table used to compute LeftShiftOverflows(). The same methodology as the previous CL suggests a 0.6% improvement. The improvement is likely bigger on mobile CPUs that have much smaller caches.

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. |

Fix typo in two argument names in stubs.
The stubs are only used in the open source version, so it wasn't caught in internal tests. |

Remove direct use of _builtin_clz.
A previous CL introduced _builtin_clz in zippy.cc. This is a GCC / Clang intrinsic, and is not supported in Visual Studio. The rest of the project uses bit manipulation intrinsics via the functions in Bits::, which are stubbed out for the open source build in zippy-stubs-internal.h. This CL extracts Bits::Log2FloorNonZero() out of Bits::Log2Floor() in the stubbed version of Bits, adds assertions to the Bits::*NonZero() functions in the stubs, and converts _builtin_clz to a Bits::Log2FloorNonZero() call. The latter part is not obvious. A mathematical proof of correctness is outlined in added comments. An empirical proof is available at https://godbolt.org/z/mPKWmh -- CalculateTableSizeOld(), which is the current code, compiles to the same assembly on Clang as CalculateTableSizeNew1(), which is the bigger jump in the proof. CalculateTableSizeNew2() is a fairly obvious transformation from CalculateTableSizeNew1(), and results in slightly better assembly on all supported compilers. Two benchmark runs with the same arguments as the original CL only showed differences in completely disjoint tests, suggesting that the differences are pure noise. |

Remove use of std::uniform_distribution<uint8_t>.
A previous CL removed use of Google-specific random number generating
functionality, such as ACMRandom, and used the C++11 standard library
instead. The CL used std::uniform_distribution<uint8_t> to generate
random bytes, which seems to be unsupported by the standard [1, 2].
For better or for worse, our toolchain does not complain. However,
Visual Studio errors out with "invalid template argument for
uniform_int_distribution: N4659 29.6.1.1 [rand.req.genl]/1e requires one
of short, int, long, long long, unsigned short, unsigned int, unsigned
long, or unsigned long long".
This CL replaces std::uniform_distribution<uint8_t> with
std::uniform_distribution<int>(0, 255) and appropriate static_cast<>s.

Use std random number generators in tests.
An earlier CL introduced absl::Uniform, which is not yet open sourced, and therefore unavailable in the open source build. This CL removes absl::Uniform and ACMRandom in favor of equivalent C++11 standard random generators. Abseil promises to be faster than the standard library, but we can afford a speed hit in tests in return for an easier open sourcing story. |

Update Travis CI configuration.
The Travis CI configuration updates reflect the following changes: * Container-based builds (sudo: false) have been removed. https://changelog.travis-ci.com/the-container-based-build-environment-is-fully-deprecated-84517 * Ubuntu Xenial (16.04) is available as a base image. https://blog.travis-ci.com/2018-11-08-xenial-release * Homebrew now has a dedicated DSL. https://docs.travis-ci.com/user/installing-dependencies/#installing-packages-on-os-x To take full advantage of VM resources, CI builds now use Ninja https://ninja-build.org/ instead of Make. |

Don't use _bzhi_u32 under MSan
MSan knows that x & 0xFF only uses the lower byte from x but it isn't as smart about _bzhi_u32(val, 8). (I'll file an upstream bug.) |

If BMI instructions are available, use BZHI to extract low bytes.
With --cpu=haswell, this results in some significant speed improvement
(notably 12-14% for html and pb). On k8, performance is not affected (as
expected). Full benchmark results for --cpu={k8,haswell} below.

How? Move boolean args of EmitLiteral, EmitCopyAtMost64 and EmitCopy to template args so that compiler generates two separate pruned versions of the functions for arg=true and arg=false. FWIW, CompressFragment function calls 1) EmitLiteral inside from a 1-level loop and 2) EmitCopy from a 2-level nested loop. CompressFragment is called from inside another while-loop from the public 'Compress' function. name old time/op new time/op delta BM_UFlat/0 [html ] 41.9µs ± 0% 41.1µs ± 0% -1.92% (p=0.000 n=10+10)

Reduce number of allocations when compressing and simplify the code.
Before we were allocating at least once: twice with large table and thrice when we used a scratch buffer. With this approach we always allocate once. name old speed new speed delta BM_UFlat/0 [html ] 2.45GB/s ± 0% 2.45GB/s ± 0% -0.13% (p=0.000 n=11+11) BM_UFlat/1 [urls ] 1.19GB/s ± 0% 1.22GB/s ± 0% +2.48% (p=0.000 n=11+11) BM_UFlat/2 [jpg ] 17.2GB/s ± 2% 17.3GB/s ± 1% ~ (p=0.193 n=11+11) BM_UFlat/3 [jpg_200 ] 1.52GB/s ± 0% 1.51GB/s ± 0% -0.78% (p=0.000 n=10+9) BM_UFlat/4 [pdf ] 12.5GB/s ± 1% 12.5GB/s ± 1% ~ (p=0.881 n=9+9) BM_UFlat/5 [html4 ] 1.86GB/s ± 0% 1.86GB/s ± 0% ~ (p=0.123 n=11+11) BM_UFlat/6 [txt1 ] 793MB/s ± 0% 799MB/s ± 0% +0.78% (p=0.000 n=11+9) BM_UFlat/7 [txt2 ] 739MB/s ± 0% 744MB/s ± 0% +0.77% (p=0.000 n=11+11) BM_UFlat/8 [txt3 ] 839MB/s ± 0% 845MB/s ± 0% +0.71% (p=0.000 n=11+11) BM_UFlat/9 [txt4 ] 678MB/s ± 0% 685MB/s ± 0% +1.01% (p=0.000 n=11+11) BM_UFlat/10 [pb ] 3.08GB/s ± 0% 3.12GB/s ± 0% +1.21% (p=0.000 n=11+11) BM_UFlat/11 [gaviota ] 975MB/s ± 0% 976MB/s ± 0% +0.11% (p=0.000 n=11+11) BM_UFlat/12 [cp ] 1.73GB/s ± 1% 1.74GB/s ± 1% +0.46% (p=0.010 n=11+11) BM_UFlat/13 [c ] 1.53GB/s ± 0% 1.53GB/s ± 0% ~ (p=0.987 n=11+10) BM_UFlat/14 [lsp ] 1.65GB/s ± 0% 1.63GB/s ± 1% -1.04% (p=0.000 n=11+11) BM_UFlat/15 [xls ] 1.08GB/s ± 0% 1.15GB/s ± 0% +6.12% (p=0.000 n=10+11) BM_UFlat/16 [xls_200 ] 944MB/s ± 0% 920MB/s ± 3% -2.51% (p=0.000 n=9+11) BM_UFlat/17 [bin ] 1.86GB/s ± 0% 1.87GB/s ± 0% +0.68% (p=0.000 n=10+11) BM_UFlat/18 [bin_200 ] 1.91GB/s ± 3% 1.92GB/s ± 5% ~ (p=0.356 n=11+11) BM_UFlat/19 [sum ] 1.31GB/s ± 0% 1.40GB/s ± 0% +6.53% (p=0.000 n=11+11) BM_UFlat/20 [man ] 1.42GB/s ± 0% 1.42GB/s ± 0% +0.33% (p=0.000 n=10+10) |
