2012-05-29Add intrinsics, code gen, assembler and disassembler support for the SSE4a ↵Benjamin Kramer
extrq and insertq instructions. This required light surgery on the assembler and disassembler because the instructions use an uncommon encoding. They are the only two instructions in x86 that use register operands and two immediates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157634 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-29Clear the entering, exiting and internal ranges of a bundle before collectingLang Hames
ranges for the instruction about to be bundled. This fixes a bug in an external project where an assertion was triggered due to spurious 'multiple defs' within the bundle. Patch by Ivan Llopard.

2012-05-28InstCombine: Fix infinite loop when encountering switch on trivial icmp.Benjamin Kramer
The test case feeds the following into InstCombine's visitSelect: %tobool8 = icmp ne i32 0, 0 %phitmp = select i1 %tobool8, i32 3, i32 0 Then instcombine replaces the right side of the switch with 0, doesn't notice that nothing changes and tries again indefinitely. This fixes PR12897. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157587 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-28PR12696: Attribute bits above 1<<30 are not encoded in bitcodeMeador Inge
Attribute bits above 1<<30 are now encoded correctly. Additionally, the encoding/decoding functionality has been hoisted to helper functions in Attributes.h in an effort to help the encoding/decoding to stay in sync with the Attribute bitcode definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157581 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-28PR1255: Case RangesStepan Dyatkovskiy
Implemented IntItem - the wrapper around APInt. Why not to use APInt item directly right now? 1. It will very difficult to implement case ranges as series of small patches. We got several large and heavy patches. Each patch will about 90-120 kb. If you replace ConstantInt with APInt in SwitchInst you will need to changes at the same time all Readers,Writers and absolutely all passes that uses SwitchInst. 2. We can implement APInt pool inside and save memory space. E.g. we use several switches that works with 256 bit items (switch on signatures, or strings). We can avoid value duplicates in this case. 3. IntItem can be easyly easily replaced with APInt. 4. Currenly we can interpret IntItem both as ConstantInt and as APInt. It allows to provide SwitchInst methods that works with ConstantInt for non-updated passes. Why I need it right now? Currently I need to update SimplifyCFG pass (EqualityComparisons). I need to work with APInts directly a lot, so peaces of code ConstantInt *V = ...; if (V->getValue().ugt(AnotherV->getValue()) { ... } will look awful. Much more better this way: IntItem V = ConstantIntVal->getValue(); if (AnotherV < V) { } Of course any reviews are welcome. P.S.: I'm also going to rename ConstantRangesSet to IntegersSubset, and CRSBuilder to IntegersSubsetMapping (allows to map individual subsets of integers to the BasicBlocks). Since in future these classes will founded on APInt, it will possible to use them in more generic ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157576 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-26SelectionDAGBuilder: When emitting small compare chains for switches order ↵Benjamin Kramer
them by using edge weights. SimplifyCFG tends to form a lot of 2-3 case switches when merging branches. Move the most likely condition to the front so it is checked first and the others can be skipped. This is currently not as effective as it could be because SimplifyCFG destroys profiling metadata when merging branches and switches. Merging branch weight metadata is tricky though. This code touches at most 3 cases so I didn't use a proper sorting algorithm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157521 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-26Since commit 157467, if reassociate isn't actually going to change an expressionDuncan Sands
then it doesn't alter the instructions composing it, however it would continue to move the instructions to just before the expression root. Ensure it doesn't move them either, so now it really does nothing if there is nothing to do. That commit also ensured that nsw etc flags weren't cleared if the expression was not being changed. Tweak this a bit so that it doesn't clear flags on the initial part of a computation either if that part didn't change but later bits did. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157518 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-25The llvm_gcda_increment_indirect_counter function writes to the arguments thatBill Wendling
are passed in. However, those arguments may be in a write-protected area, as far as the runtime library is concerned. For instance, the data could be placed into a 'linkedit' section, which isn't writable. Emit the code from llvm_gcda_increment_indirect_counter directly into the function instead. Note: The code for this is ugly, and can lead to bloat. We should look into simplifying this code instead of having all of these branches. <rdar://problem/11181370> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157505 91177308-0d34-0410-b5e6-96231b3b80d8
