This also fixes a real bug in the open-source implementation of ReadFileToStringOrDie(); it would not detect errors correctly. I had to go through some pains to avoid performance loss as the types were changed; I think there might still be some with 32-bit if and only if LFS is enabled (ie., size_t is 64-bit), but for regular 32-bit and 64-bit I can't see any losses, and I've diffed the generated GCC assembler between the old and new code without seeing any significant choices. If anything, it's ever so slightly faster. This may or may not enable compression of very large blocks (>2^32 bytes) when size_t is 64-bit, but I haven't checked, and it is still not a supported case. ------------------------------------------------------------------------ r55 | snappy.mirrorbot@gmail.com | 2012-01-04 11:46:39 +0100 (Wed, 04 Jan 2012) \ | 6 lines Add a framing format description.

This seems to work because in most of the branches, the compiler can evaluate âip_limit_ - ipâ in a more efficient way than reloading ip_limit_ from \ memory (either by already having the entire expression in a register, or reconstructing it from âavailâ, or something else). Memory loads, even from L1, are \ seemingly costly in the big picture at the current decompression speeds.

We do the fast-path step as soon as possible; in fact, as soon as we know the literal length. Since we usually hit the fast path, we can then skip the checks for long literals and available input space (beyond what the fast path check already does). Note that this changes the decompression Writer API; however, it does not change the ABI, since writers are always templatized and as such never cross compilation units. The new API is slightly more general, in that it doesn't hard-code the value 16. Note that we also take care to check for len <= 16 first, since the other two checks almost always succeed (so we don't want to waste time checking for them until we have to). The improvements are most marked on Nehalem, but are generally positive on other platforms as well. All microbenchmarks are 64-bit, opt.

Whenever we try to enter a copy fast-path, there is a certain cost in checking that all the preconditions are in place, but it's normally offset by the fact that we can usually take the cheaper path. However, in a certain path we've already established that "avail < literal_length", which usually \ means that either the available space is small, or the literal is big. Both will disqualify us from taking the fast path, and thus we take the hit from the precondition checking without gaining much from having a fast path. Thus, simply don't try the fast path in this situation -- we're already on a slow path anyway (one where we need to refill more data from the reader). I'm a bit surprised at how much this gained; it could be that this path is more common than I thought, or that the simpler structure somehow makes the compiler happier. I haven't looked at the assembler, but it's a win across the board on both Core 2, Core i7 and Opteron, at least for the cases we typically care about. The gains seem to be the largest on Core i7, though.

Looking up into and decoding the values from char_table has long shown up as a hotspot in the decompressor. While it turns out that it's hard to make a more efficient decoder for the copy ops, the literals are simple enough that we can decode them without needing a table lookup. (This means that 1/4 of the table is now unused, although that in itself doesn't buy us anything.) The gains are small, but definitely present; some tests win as much as 10%, but 1-4% is more typical. These results are from Core i7, in 64-bit mode; Core 2 and Opteron show similar results. (I've run with more iterations than unusual to make sure the smaller gains don't drown entirely in noise.)

Performance is, as expected, mostly flat -- there's a curious ~3-5% loss in the "lsp" test, but that test case is so short it is hard to say anything definitive about why (most likely, it's some sort of unrelated effect). R=jeff ------------------------------------------------------------------------ r38 | snappy.mirrorbot@gmail.com | 2011-06-02 19:59:40 +0200 (Thu, 02 Jun 2011) \ | 52 lines Speed up decompression by caching ip_. It is seemingly hard for the compiler to understand that ip_, the current input pointer into the compressed data stream, can not alias on anything else, and thus using it directly will incur memory traffic as it cannot be kept in a register. The code already knew about this and cached it into a local variable, but since Step() only decoded one tag, it had to move ip_ back into place between every tag. This seems to have cost us a significant amount of performance, so changing Step() into a function that decodes as much as it can before it saves ip_ back and returns. (Note that Step() was already inlined, so it is not the manual inlining that buys the performance here.) The wins are about 3-6% for Core 2, 6-13% on Core i7 and 5-12% on Opteron (for plain array-to-array decompression, in 64-bit opt mode). There is a tiny difference in the behavior here; if an invalid literal is encountered (ie., the writer refuses the Append() operation), ip_ will now point to the byte past the tag byte, instead of where the literal was originally thought to end. However, we don't use ip_ for anything after DecompressAllTags() has returned, so this should not change external behavior in any way.

I've kept the copyright notice, since Martin is obviously the author here; he has signed the contributor license agreement, though, so this should not hinder Google's use in the future.
