Victor Costan	d1daa83044	Remove inline qualifier from static variables. This feature requires C++17. Fortunately, inline is useful for header declarations, which may be included in multiple compilation units. The declarations modified by this CL occur in a single compilation unit.

Snappy Team	3b571656fa	1) Improve the lookup table data to require less instructions to extract the necessary data. We now store len - offset in a signed int16, this happens to remove masking offset in the calculations and the calculations that need to be done precisely give the flags that we need for testing correctness. 2) Replace offset extraction with a lookup mask. This is less uops and is needed because we need to special case type 3 to always return 0 as to properly trigger the fallback. 3) Unroll the loop twice, this removes some loop-condition checks AND it improves the generated assembly. The loop variables tend to end up in a different register requiring mov's having two consecutive copies allows the elision of the mov's. PiperOrigin-RevId: 346663328	2020-12-14 02:48:03 +00:00
Shahriar Rouf	a9730ed505	Optimize zippy decompression by making IncrementalCopy faster. When SSSE3 is available: - Use PSHUFB (_mm_shuffle_epi8) to handle pattern size 1 to 15 (previously it handled size 1 to 7). - This enables us to do 16 byte copies instead of 8 bytes copies because we know that the pattern size >= 16. - Use shuffle-reshuffle strategy to generate the next pattern after loading the initial pattern. This enables us to write 4 conditionals (similar to when pattern size >= 16) which would allow FDO to layout the code with respect to actual probabilities of each length. - The PSHUFB masks are now generated programmatically at compile-time. When SSSE3 is unavailable: - No change. In both cases: - assert(op < op_limit) in IncrementalCopy so that we can check 'op_limit <= buf_limit - 15' instead of 'op_limit <= buf_limit - 16'. All existing call sites of IncrementalCopy guarantee this. 'bin' case is notably >20% faster because it has many repeated character patterns (i.e. pattern_size = 1).

Luca Versari	6835abd953	Change hash function for Compress. ((ab)>>18) & mask has higher throughput than (ab)>>shift, and produces the same results when the hash table size is 2**14. In other cases, the hash function is still good, but it's not as necessary for that to be the case as the input is small anyway. This speeds up in encoding, especially in cases where hashing is a significant part of the encoding critical path (small or uncompressible files).

The load-to-use latency is 5 cycles, in previous cl/303353110 we removed the load in lieu of "shrd" to align previous loads. Unfortunately "shrd" itself has a latency of 4 cycles, we'd prefer "shrx" which takes 1 cycle for variable shifts. 2)Maximally use data already computed. The above trick calculates 5 bytes of useful data. So in case we need to search for new match we can use this for the first search (which is one byte further).

Snappy Team	0faf56378e	This cl does two things 1) It shaves of a few cycles from the data dependency chain. By using "shrd" instead of a load. 2) The important loop is finding small copies (4-12) which are either "copy 1", or "copy 2" depending if the offset fits <2048. It turns out that this is a branch that is mispredicted often. Due to the long dependency chain the CPU is running with IPC~1 anyway so we can freely add instructions to instead emit copies branchfree. This reduces the branch misspredicts from 15% to 11% (for BM_ZFlat/6 txt1) and from 5.6% to 4% (for BM_ZFlat/10 or pb). PiperOrigin-RevId: 303328967	2020-04-11 04:40:48 +00:00
Snappy Team	0c7ed08a25	The result on protobuf benchmark is around 19%. Results vary by their propensity for compression. As the frequency of finding matches influences the amount of branch misspredicts and the amount of hashing. Two ideas 1) The code uses "heuristic match skipping" has a quadratic interpolation. However for the first 32 bytes it's just every byte. Special case 16 bytes. This removes a lot of code. 2) Load 64 bit integers and shift instead of reload. The hashing loop has a very long chain data = Load32(ip) -> hash = Hash(data) -> offset = table[hash] -> copy_data = Load32(base_ip + offset) followed by a compare between data and copy_data. This chain is around 20 cycles. It's unreasonable for the branch predictor to be able to predict when it's a match (that is completely driven by the content of the data). So when it's a miss this chain is on the critical path. By loading 64 bits and shifting we can effectively remove the first load. PiperOrigin-RevId: 302893821	2020-04-11 04:40:39 +00:00
Snappy Team	3c77e01459	1) Make the output pointer a local variable such it doesn't need a load add store on it's loop carried dependency chain. 2) Reduce the input pointer loop carried dependency chain from 7 cycles to 4 cycles by using pre-loading. This is a very subtle point. 3) Just brutally copy 64 bytes which removes a difficult to predict branch from the inner most loop. There is enough bandwidth to do so in the intrinsic cycles of the loop. 4) Implement limit pointers that include the slop region. This removes unnecessary instructions from the hot path. 5) It seems the removal of the difficult to predict branch has removed the code sensitivity to alignment, so remove the asm nop's.

costan	3f194acb57	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.	2019-01-08 13:49:15 -08:00
costan	97a20b480f	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.

costan	4f0adca400	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.	2019-01-08 06:44:11 -08:00

costan	81d444e4e4	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.	2019-01-06 12:49:08 -08:00

atdt	136b3ebc31	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.

nafi	eb47f79631	Optimize by about 0.5%. 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)
