2013-01-21Remove the comma from the last enumerator to fix -pedantic warnings.Chandler Carruth

2013-01-21Introduce a generic interface for querying an operation's expectedChandler Carruth
lowered cost. Currently, this is a direct port of the logic implementing isInstructionFree in CodeMetrics. The hope is that the interface can be improved (f.ex. supporting un-formed instruction queries) and the implementation abstracted so that as we have test cases and target knowledge we can expose increasingly accurate heuristics to clients. I'll start switching existing consumers over and kill off the routine in CodeMetrics in subsequent commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172998 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-20Add instruction encodings / disassembly support 3r instructions.Richard Osborne
It is not possible to distinguish 3r instructions from 2r / rus instructions using only the fixed bits. Therefore if an instruction doesn't match the 2r / rus format try to decode it as a 3r instruction before returning Fail. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172984 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-20Revert 172708.Nadav Rotem
The optimization handles esoteric cases but adds a lot of complexity both to the X86 backend and to other backends. This optimization disables an important canonicalization of chains of SEXT nodes and makes SEXT and ZEXT asymmetrical. Disabling the canonicalization of consecutive SEXT nodes into a single node disables other DAG optimizations that assume that there is only one SEXT node. The AVX mask optimizations is one example. Additionally this optimization does not update the cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172968 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-20Added IRBuilder::CreateFPExtOrFPTrunc.Michael Gottesman
This method serves an analogous purpose to CreateZExtOrTrunc/CreateSExtOrTrunc but for floating point types. In detail, it provides a manner when one is handling conversions of floating point types of automatically selecting fpext, fptrunc, or identity depending on the relative bitsize of the source and destination types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172957 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-20docs: Nuke the old release notes.Sean Silva
This change also removes a bunch of boilerplate and stuffing which made it unnecessarily hard to navigate and see the comparatively miniscule actual content that was added to this document during the 3.2 development period (or maybe even sticking around from earlier releases...). The new organization (a flat list) optimizes for making it easy for people who know about changes to add them to the document. It's completely trivial for anyone with basic knowledge of LLVM to come in later (such as when preparing for the actual release) and cluster any changes into logical groups. However, I have left some comments indicating how to add larger descriptions, if someone is feeling adventurous ;) Hopefully this organization will highlight how little effort is being put into producing accurate, high-quality release notes, prompting a corresponding improvement for the 3.3 release. I have preserved the changes to this document that are not present in the 3.2 release notes. There were only two... I'm pretty sure we've been busier than that... (version control shows +213347/-173656 raw lines just in the LLVM repo since the 3.2 release). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172954 91177308-0d34-0410-b5e6-96231b3b80d8
