* Fix for PR18921, "vmov" part.Stepan Dyatkovskiy2014-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | Added support for bytes replication feature, so it could be GAS compatible. E.g. instructions below: "vmov.i32 d0, 0xffffffff" "vmvn.i32 d0, 0xabababab" "vmov.i32 d0, 0xabababab" "vmov.i16 d0, 0xabab" are incorrect, but we could deal with such cases. For first one we should emit: "vmov.i8 d0, 0xff" For second one ("vmvn"): "vmov.i8 d0, 0x54" For last two instructions it should emit: "vmov.i8 d0, 0xab" P.S.: In ARMAsmParser.cpp I have also fixed few nearby style issues in old code. Just for keeping method bodies in harmony with themselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207080 91177308-0d34-0410-b5e6-96231b3b80d8

Hopefully this will help us write increasingly full featured iterators.

* [ADT] Add a generic iterator utility for adapting iterators much likeChandler Carruth2014-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | Boost's iterator_adaptor, and a specific adaptor which iterates over pointees when wrapped around an iterator over pointers. This is the result of a long discussion on IRC with Duncan Smith, Dave Blaikie, Richard Smith, and myself. Essentially, I could use some subset of the iterator facade facilities often used from Boost, and everyone seemed interested in having the functionality in a reasonably generic form. I've tried to strike a balance between the pragmatism and the established Boost design. The primary differences are: 1) Delegating to the standard iterator interface names rather than special names that then make up a second iterator-like API. 2) Using the name 'pointee_iterator' which seems more clear than 'indirect_iterator'. The whole business of calling the '*p' operation 'pointer indirection' in the standard is ... quite confusing. And 'dereference' is no better of a term for moving from a pointer to a reference. Hoping Duncan, and others continue to provide comments on this until we've got a nice, minimal abstraction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207069 91177308-0d34-0410-b5e6-96231b3b80d8

* [InstCombine][x86] Constant fold psll intrinsics.Michael J. Spencer2014-04-24
| | | | | | | | | | | | This excludes avx512 as I don't have hardware to verify. It excludes _dq variants because they are represented in the IR as <{2,4} x i64> when it's actually a byte shift of the entire i{128,265}. This also excludes _dq_bs as they aren't at all supported by the backend. There are also no corresponding instructions in the ISA. I have no idea why they exist... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207058 91177308-0d34-0410-b5e6-96231b3b80d8

* Optimize some special cases for SSE4a insertqiFilipe Cabecinhas2014-04-24
| | | | | | | | | | | | | | | | | | | | Summary: Since the upper 64 bits of the destination register are undefined when performing this operation, we can substitute it and let the optimizer figure out that only a copy is needed. Also added range merging, if an instruction copies a range that can be merged with a previous copied range. Added test cases for both optimizations.
