* First implementation of:Stepan Dyatkovskiy2012-04-251-0/+133
| | | | | | | | | | | - FlatArrayMap. Very simple map container that uses flat array inside. - MultiImplMap. Map container interface, that has two modes, one for small amount of elements and one for big amount. - SmallMap. SmallMap is DenseMap compatible MultiImplMap. It uses FlatArrayMap for small mode, and DenseMap for big mode. Also added unittests for new classes and update for ProgrammersManual. For more details about new classes see ProgrammersManual and comments in sourcecode. llvm-svn: 155557
* SparseSet: Add support for key-derived indexes and arbitrary key types.Andrew Trick2012-04-201-1/+1
| | | | | | | | | | | | | | | | | | | This nicely handles the most common case of virtual register sets, but also handles anticipated cases where we will map pointers to IDs. The goal is not to develop a completely generic SparseSet template. Instead we want to handle the expected uses within llvm without any template antics in the client code. I'm adding a bit of template nastiness here, and some assumption about expected usage in order to make the client code very clean. The expected common uses cases I'm designing for: - integer keys that need to be reindexed, and may map to additional data - densely numbered objects where we want pointer keys because no number->object map exists. llvm-svn: 155227

Currently this only provides a 'fpaccuracy' value, which may be a number in ULPs or the keyword 'fast', however the intent is that this will be extended with additional information about NaN's, infinities etc later. No optimizations have been hooked up to this so far. llvm-svn: 154822

* Revert a series of commits to MCJIT to get the build working in CMakeChandler Carruth2012-03-221-4/+0
| | | | | | | | | | | | | | | (and hopefully on Windows). The bots have been down most of the day because of this, and it's not clear to me what all will be required to fix it. The commits started with r153205, then r153207, r153208, and r153221. The first commit seems to be the real culprit, but I couldn't revert a smaller number of patches. When resubmitting, r153207 and r153208 should be folded into r153205, they were simple build fixes. llvm-svn: 153241

* Add support to the hashing infrastructure for automatically hashing bothChandler Carruth2012-03-071-0/+6
| | | | | | | | | | | | | | | | | | integral and enumeration types. This is accomplished with a bit of template type trait magic. Thanks to Richard Smith for the core idea here to detect viable types by detecting the set of types which can be default constructed in a template parameter. This is used (in conjunction with a system for detecting nullptr_t should it exist) to provide an is_integral_or_enum type trait that doesn't need a whitelist or direct compiler support. With this, the hashing is extended to the more general facility. This will be used in a subsequent commit to hashing more things, but I wanted to make sure the type trait magic went through the build bots separately in case other compilers don't like this formulation. llvm-svn: 152217

* Simplify the pair optimization. Rather than using complex type traits,Chandler Carruth2012-03-021-0/+20
| | | | | | | | | | | | | | just ensure that the number of bytes in the pair is the sum of the bytes in each side of the pair. As long as thats true, there are no extra bytes that might be padding. Also add a few tests that previously would have slipped through the checking. The more accurate checking mechanism catches these and ensures they are handled conservatively correctly. Thanks to Duncan for prodding me to do this right and more simply. llvm-svn: 151891

* We really want to hash pairs of directly-hashable data as directlyChandler Carruth2012-03-021-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | hashable data. This matters when we have pair<T*, U*> as a key, which is quite common in DenseMap, etc. To that end, we need to detect when this is safe. The requirements on a generic std::pair<T, U> are: 1) Both T and U must satisfy the existing is_hashable_data trait. Note that this includes the requirement that T and U have no internal padding bits or other bits not contributing directly to equality. 2) The alignment constraints of std::pair<T, U> do not require padding between consecutive objects. 3) The alignment constraints of U and the size of T do not conspire to require padding between the first and second elements. Grow two somewhat magical traits to detect this by forming a pod structure and inspecting offset artifacts on it. Hopefully this won't cause any compilers to panic. Added and adjusted tests now that pairs, even nested pairs, are treated as just sequences of data. Thanks to Jeffrey Yasskin for helping me sort through this and reviewing the somewhat subtle traits. llvm-svn: 151883
* Add support for hashing pairs by delegating to each sub-object. There isChandler Carruth2012-03-021-0/+11
| | | | | | | | | | | | | | | | | an open question of whether we can do better than this by treating pairs as boring data containers and directly hashing the two subobjects. This at least makes the API reasonable. In order to make this change, I reorganized the header a bit. I lifted the declarations of the hash_value functions up to the top of the header with their doxygen comments as these are intended for users to interact with. They shouldn't have to wade through implementation details. I then defined them at the very end so that they could be defined in terms of hash_combine or any other hashing infrastructure. Added various pair-hashing unittests. llvm-svn: 151882
* Remove the misguided extension here that reserved two special values inChandler Carruth2012-03-021-11/+1
| | | | | | | | | | | the hash_code. I'm not sure what I was thinking here, the use cases for special values are in the *keys*, not in the hashes of those keys. We can always resurrect this if needed, or clients can accomplish the same goal themselves. This makes the general case somewhat faster (~5 cycles faster on my machine) and smaller with less branching. llvm-svn: 151865

* Rewrite LLVM's generalized support library for hashing to follow the APIChandler Carruth2012-03-011-25/+286
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of the proposed standard hashing interfaces (N3333), and to use a modified and tuned version of the CityHash algorithm. Some of the highlights of this change: -- Significantly higher quality hashing algorithm with very well distributed results, and extremely few collisions. Should be close to a checksum for up to 64-bit keys. Very little clustering or clumping of hash codes, to better distribute load on probed hash tables. -- Built-in support for reserved values. -- Simplified API that composes cleanly with other C++ idioms and APIs. -- Better scaling performance as keys grow. This is the fastest algorithm I've found and measured for moderately sized keys (such as show up in some of the uniquing and folding use cases) -- Support for enabling per-execution seeds to prevent table ordering or other artifacts of hashing algorithms to impact the output of LLVM. The seeding would make each run different and highlight these problems during bootstrap. This implementation was tested extensively using the SMHasher test suite, and pased with flying colors, doing better than the original CityHash algorithm even. I've included a unittest, although it is somewhat minimal at the moment. I've also added (or refactored into the proper location) type traits necessary to implement this, and converted users of GeneralHash over. My only immediate concerns with this implementation is the performance of hashing small keys. I've already started working to improve this, and will continue to do so. Currently, the only algorithms faster produce lower quality results, but it is likely there is a better compromise than the current one. Many thanks to Jeffrey Yasskin who did most of the work on the N3333 paper, pair-programmed some of this code, and reviewed much of it. Many thanks also go to Geoff Pike Pike and Jyrki Alakuijala, the original authors of CityHash on which this is heavily based, and Austin Appleby who created MurmurHash and the SMHasher test suite. Also thanks to Nadav, Tobias, Howard, Jay, Nick, Ahmed, and Duncan for all of the review comments! If there are further comments or concerns, please let me know and I'll jump on 'em. llvm-svn: 151822

| | | | | | | | | | | | | chip in r139383, and the PSP components of the triple are really annoying to parse. Let's leave this chapter behind. There is no reason to expect LLVM to see a PSP-related triple these days, and so no reasonable motivation to support them. It might be reasonable to prune a few of the older MIPS triple forms in general, but as those at least cause no burden on parsing (they aren't both a chip and an OS!), I'm happy to leave them in for now. llvm-svn: 151156
